***Sorry this was installed on an 80 but I will be doing the same on my 60***

Hi there folks. Its time for another totally useless, but I thought it was cool, HOW TO that will never find its way into the FAQs :flipoff2:

The idea started actually last year while in Mammoth during a blizzard. On the way out of the town, while trying to get to the 395, the road had been closed by the CHP. Well not closed so much as you had to have a CHP escort. We wound up waiting our turn for close to 2 hours. During this time we, just like everyone else, would turn off the truck until it was time to move. During this time we happened upon a family that was in a 100 series. It seems their dual TVs and dual DVD players and the 0º weather took its toll on the batteries because they were stuck. We saw the hood up and car after car would just drive right on past. Finally we had driven up to them to see how we could help. Jumper cables to the rescue.

Wooops!

No jumper cables. Turns out the last person we helped...helped themselves to the cables and we didn't notice. Luckily ANOTHER FJ80 came by with cables and we got the 100 started. Although it was pure comedy watching these guys try to decide where to ground and which cable goes where. All ended well. This got us thinking. Why not have battery cables that would only work for our truck, would be easily accessible, would be more foolproof to hook up AND that we could turn on and use without even opening up the hood.

Hence.........


"THE WORLD'S MOST EXPENSIVE BATTERY CABLES"
(or, "Joey has too much time on his hands" OR
"another 80 owner with more money than brains")


When I started this I had decided that I wanted to use cable quick disconnects. The same type used for powering up winches. I wanted them hooked up to the auxiliary battery because if I am going to fry a battery, I'd rather it be that one. I also wanted the ability to turn it on via a solenoid and use a dash mounted switch. All without lifting the hood. :D :princess:

I contacted Wrangler Power Products and was working directly with Stan Hackathorn. I would be sourcing almost all of the necessary products from him/them for this project. No affiliation although if you are reading this Stan...freebies are always welcome. :D

Items needed:
• Aux. battery. of course you can use the main but I've seen stupid things cause batteries to go boom.
Wrangler's 200Amp solenoid 29-983 ($72.00)
• A few feet both both red and black battery cable. I used 1/0 but you can use 4 AWG just fine. 010-000013 ($4.37 ft. for black), 010-000014 ($4.45 ft. for red)
• (2) 1/0 Pos. lugs 014-000032 ($3.92 or $1.96 ea.)
• (2) 1/0 Neg. lugs 014-000031 ($2.86 or $1.43 ea.)
• (4) quick disconnect pins 014-009042 ($13.96 or $3.49 ea.)
• (2) quick disconnect Lexan 903 housings 012-009032 ($3.91 ea.)
• (1) quick disconnect dust cover 372-000905 ($4.60 ea.)
• (1) mechanical lock for 903 housings (optional)
• (2) neg terminal boots 372-003070 ($2.54 or $1.27 ea.)
• 16ft (or more if required) of 2AWG TANDEM cable 010-202020 ($86.24 or $5.39 ft.)
• (2) battery hand clamps 372-015400 ($8.99 red), 372-015401 ($8.99 black)
• 20 ft of black fish net stocking sheathing 015-000294 ($17.60)
• several adhesive shrink tubes 015-001751 ($2.65 ft)
• Hammer indent punch ($15.00)
• 15 ft of 14AWG wire
• wire connectors
• .25" split loom
• room for another fuse

The first step is deciding where to put the solenoid. I went with Wrangler's 200Amp continuous duty solenoid but its mounting orientation, I thought, was kinda limiting. I decided that the best place to affix this would be between the two horns on that metal bracket that they are connected to. Now the spacing between the solenoid is just slightly too narrow so you will have to widen it slightly. Again, this is only if you are mounting it here. I wanted it out of the way and more or less hidden so this made sense for me.

Once there you have a small power post and a small ground post. It doesn't matter which you use as ground and which you use as power. I used the mounting bracket as the ground. Just a small piece of wire with an eyelet connector and shrink tubing on both ends.

The power wire will need to be longer. You COULD mount the switch near the quick disconnect or even in the engine bay but this didn't make sense to me because I wanted to use the cables without having to lift the hood. So for me that meant bringing it into the cab.

I had already bought an extra hazard witch and had figured out how to relabel a switch

From there I just made a new label and installed the switch. I was able to figure out which wires I needed to connect in order to complete the circuit so I brought the wire from the solenoid and connected it to the switch. From the switch I connected it to my new aux. fuse panel with a 5A fuse.

The switch in the dash now turns the solenoid off/on to allow or not allow current through.

I now used the crimper I got from AirGas for $15 and started making cables. The 1/0 cables I got from Wrangler was actually really easy to work worth. I was dreading trying to manipulate the cable but the casing was soft and it uses 100s of copper wires so it was easy to work with.

I had already purchased my Odyssey battery, ala Sears, for my dual battery set up. I went with the M series just so that I would get the dual attachment points on the battery. The threaded posts is what I used as the anchor points for the cables that are going to be used for the quick disconnect.

After mounting the solenoid, adding the battery, I then needed a place to put the actually receiving end of the quick disconnect. Now this can be anyway accessible. I chose the cross member of my damage multiplier. Yeah yeah, it will be replaced soon enough. So two small holes drilled and now that piece is attached.

Now its time to measure the run for the cables. I decided to run the thick cables behind the headlights and then into the space behind the grill. this mean just remove the overflow tank and moving it aside. Now take any random wire you have around and run the wire from the positive side of the battery, through the headlight opening, behind the grill, to the back end of the disconnect. That is your positive run. I think mine measured 28". Now cut 28" from your 1/0 cables, strip the ends, select a quick disconnect pin and battery lug. Using a crimper, crimp the lugs to the cable. For me it meant smashing the hell out of the indent crimper. :D

Now because the cable was running in between sheet metal, I thought it would be a good idea to run sheathing with the cable. So I ran some of that cool black fish net stocking kinda stuff over the cable and pulled taught. Then I used an adhesive type shrink tube to adhere the sheath, cable and lug together. Then did the same to the other side. Now I attached the pin into the quick disconnect by pushing the pin into the socket. You will here a loud CLICK. Now for routing I routed the cables in the grill but obviously you don't have to. But for me I could now route the cable from the disconnect, through the grill, into the space behind the headlight and alongside the battery and up and connecting to the top of the battery. Perfect fit.

For the negative, you would need to run from the ground of the battery, to the solenoid. Then from the other post of the solenoid to the quick disconnect. There is limited room to attach to the solenoid but it wasn't impossible. BTW, if you are going to add terminal covers, PLEASE add them before crimping your lugs. GRRRR!

So that is it for the vehicle part.

Now Wrangler sells the actual battery cables as a kit, I didn't just want those. I wanted the cool mechanical latch and I wanted to add the sheathing so I purchased 16 ft. of 4AWG and the clamps to assemble my own jumper cables.

When making your own jumper cables, its important to run the cable through the hand clamps BEFORE you crimp the lug that attaches to the clamp. Man I'm dumb. From there I ran a shrink tune then the sheathing. This just goes on like a really long condom. Its all to familiar, I'm sure you all know what I am talking about :fipoff2:

Even though the 4AWG cable I got WAS tandem, I decided I wanted the cool sheathing anyway. So I ran it through and attached at one end, leaving about 3 ft of naked cable, then attached using the shrink tubing.

I then pulled the sheathing taught all the way to the other end of the 16 ft. cable and taped it in place. I added the quick disconnect pin lugs and then individually added the shrink tubing. Make sure you have another shrink tube over the cable. This is where you pull the sheathing taught and then heat up the shrink tube to hold it in place about 6 inches from the tip of the connectors. At this point you can insert the pins into the quick disconnect. There is a bolt, nut and retainer clip that attaches to the disconnect housing to keep the cables in place.

NOW........

When someone needs a jump, THEY lift their hood. You bring out your shiny new cables. Attach them to the quick disconnect on your bumper and lock into place. Attack the clamps to the other vehicle. And press the switch! BAM! You have a started car. Turn off the switch and you now have harmless jumper cables.

The only thing I will be adding now is a large LED light near the disconnect to let me know that the jumper cables are active.
 
that really is pretty cool.

so how much did it cost you? im atracted to fancy sometimes over thought out items.
 
That's damn bitchin' ...

I think I'll do that to mine... Someday. :rolleyes:

Oh trust me, its well thought out. Its also pretty darn blingy. I won't go quite so excessive on the 60. The 80 is my pink panty mobile so it needs to be more :princess:
 
Sweet!!! but I'll stick to opening my hood so they can see my V8 :D :D :D

See if I was rocking the V8 then I would rig it up so that every time the hood opens, a "god ray" would shine down on it and then a recording of harps with a chorus of angels would play from the speakers. :flipoff2:
 
600 bones?!
what the hell cost so much?
 
oh and how does it work if you need to be jumped? old school way or will your fancy thing work?

Me figuring out what the hell I am doing and what I wanted. Most of that money went into just having the part to look at. If you look at the updated parts list (with part# and price) you will see that its probably around half that.

The cable and solenoid are the big ticket items coming in at around $200. So between all of the other odds and ends it could be around $300ish.

But like I wrote, you can easily do it cheaper if you want. I like overkill :D
 
What I love, though, is my wife being able to help someone else out with confidence. I am also considering some type of polarity LED as well. I'm working on it.

This is a very good question...

ASSUMING you don't have dual batteries...

OR you do and you still managed to kill both :hillbilly: ...

Then this will NOT work for you. The reason is the starting vehicle needs to have the negative terminal connected and the dead vehicle needs to have the negative terminal grounded somewhere OTHER than the negative terminal. So wont work.

Already thinking of a solution.....
