Not sure if thats the right name, but the terminals the connect to the batter (from the pos and neg. Mine are looking tired so I want to replace them. What are people swapping them out with? Tried to search, but I don't think I am using the right terms.
 
Mil-Spec terminals. I bought mine from Wrangler Power Products, but you can get them from NAPA now. Very nice.

To slightly hijack this thread, when installing these new terminals, I will need to cut the old fitting off and install a copper fittings around the end of the wire. What is the best way to make sure I have a good connection b/n the fittings and the wire?
 
Yes cut off the old one. Best is to crimp AND solder onto new eyelet. Make sure you have enough room to work with. The driver's side stock cables are already kinda tight.
 
Anyone ever used the high end terminals that most car audio companies market?

They look to be made for this kind of stuff & a little better than ^ since you plug the wires directly in to them.

Thoughts?

I've used them to varying success. Clamping down the wire with an allen plug never worked as well as crimping a lead on for me. I'll second the mil spec terminals. They have worked nicely.

Yeah. Those screw-in allen type never hold the cable well. It will come loose soon enough. Mil-spec terminals are all you want!
 
The factory terminals are actually very good and what I normally recommend *except* for winching.

If you don't have a winch and don't plan on getting one just go to the Toyota dealership and buy some new terminals. They're not cheap but they're very well made and will easily last the life of the vehicle at this point.

If you're winching you should use mil-spec or style terminals with proper crimped eyelets. Your local stereo shop can help you with the crimping and eyelets, as can your local marine shop.
 
Thx

I have a winch & plan on adding a fridge soon as well.
 
Go with the mil spec style. They're less likely to melt with the long and high current draw that a winch can dish out.

The stereo bling stuff is just that, bling. On a boat, I'd consider gold plating but not on a car. And this is coming from a guy that used to do stereo stuff for a living, and had 2kw of amplifier power in the last car that had an aftermarket stereo in it.
 
So, to do things the best (but a little costly) way, I would say get the military style terminals, add on these Jegs quick release ends, and spray with dielectric grease.

I have the military ends on my 80 and they are the kittens mittens, I upgraded the cabling from the batteries to grounds, and oversized the cable to my starter, I have dual batteries, but also the 5.9 cummins and have cold weather starts 1/3 of the year.

The quick disconnects are nice if you have dual batteries and a ready welder as well I suspect.

I'm no expert and I don't see anything wrong with them from a reliability and longevity standpoint but my OEM terminals, the wrap around band style on my 97 LC, has slight gaps around the circumference of the post where it's not perfectly flush. I would guess that about 70-75% of the band is tight against the post. I don't know if other styles are any better, but I'm just putting this out there...

Not sure if it's the post that's out of round or the connector.

I use the copper lugs that you can get at good autoparts stores, then crimp them with a nicopress tool and solder the connection. A good shrinkwrap with dielectric grease at the end of the lug and I'm done.

Sounds like yours have been tweeked from overtightening in the past. If you look under the hood of any of the new cars on the dealers lot, that's what they *should* look like, and will, if you put new ones in.

I install these all the time when some clown puts $0.99 terminals onto a car and complains about electrical issues, starting problems, etc.

Not saying they're the best, but they're what I prefer to install on Toyotas. Light too, if you're driving a sports car.

Again, I use them all the time except for winch equipped trucks.
