Welcome to the dark side, it’s much faster

Thanks, haha, definitely excited.

Hell yeah man, you're going to love it with the H55F when you're done!

Thanks, yea I am excited, I deffinitely love that it has the H55F and twin stick kit. Other than all of the ARB bolt-ons(bumper, roof rack, OME lift), the H55 was the big reason I bought it! I have the NV4500 in my FJ40 and do like that it has a bigger overdrive, but now that I have gotten used to driving behind the H55 I really like it. Now to just give it a little more power!

So I’ve been combing over the forums since the fall to gather info. I’m seeing plenty of good swap suggestions and info.

This thread is particularly helpful:

how-to-ls-swap-a-fj60-or-fj62-quick-and-dirty-guide-for-regular-folks-wanting-to-do-an-engine-swap-in-their-driveway

But I haven’t really found a good description of how much wiring I can remove. I’m trying to save everything and not cut anything. I have the FSM so I’ll dive in tonight, but so far on the main engine harness, the only thing I can see that I need to save is the Temp sender wire for the cluster, so I removed it in one piece by disconnecting everything. Hoping to help out another Mud member in need of parts as u go…

Plenty more to clean up and figure out, going to look at the FSM diagrams for what’s left & what I need to merge with the LS harness. More to come

As you saw you don't need anything from the 3FE engine harness besides the cluster wire which runs through the ECM. I like to De-pin that wire right from the plug on the cluster and leave the engine harness intact. Especielly since you need to run tach, CEL and DBW wires up to that area though the driver's side firewall anyways.

Here to help with all the parts you'll need for the swap

Feels great to get all that wiring out. When I did my swap I ended up pulling my dash to get it all out without cutting. Definitely added a lot of time, but I’m glad I did it.

 

[BurntToast]

Agreed, I also pulled the dash. Much cleaner that way.

Nice, that sounds a lot better than trying to cut into everything and merge the two.... Thanks for all the info, I will definitely be calling and placing an order!

Thanks! Sounds like the way to go! Mine is cracked and I saw a decent used one, maybe I should see if it’s still available. Yea, I’m hoping to just disconnect and remove wiring, I want everything to look clean & not be a rats nest, I hate hacked off wires going to nowhere….

What harness are you going with?

 

[huminajumina]

What harness are you going with?

I’ve got a factory harness & ECM that came with the motor, it’s clean and in good condition. Going to go through it on the workbench and remove all the 4L60 part of the harness and clean it up to get it ready for install. I bought a PSI ECM for another project years ago, I have considered buying a harness if I get lazy or sending it out to one of the other vendors, but we’ll see.

Nice. Solid plan. And the bonus is that you'll talk yourself into redoing all the foam on your HVAC since that'll be 90% out as well at that point.

 

[huminajumina]

Haha, yea exactly.....already saw a post where someone else was asking about the foam after finding their ECM and wondering what the foam was behind it...... I shoulda stuck with FJ40s the heater box is so simple!


Well after about 45hrs without electricity, my weekend is shot and I am ready for another solid week of work. Luckily we had no damage as a small but intense Thunderstorm ripped through the area Saturday night, 5 power poles were snapped off down the road. Tons of trees blown over just a few miles north. I've been fixing neighbors generators, running extension cords and trying to find a place to take a shower for the past 2 days.


Heres some of the poles down right around the corner from my house.

Trees down everywhere

Easter Sunday I went to 3 stores, one closed with no power, one sold out, and the third said this was 1 of 4 remaining generators left on the shelf...I didn't get to look at any info, just grabbed it, thanked them for working on Easter, paid and left!!! The wife was happy, the food in the freezer and fridge was saved.

But, before the storm, I was able to get a few things done before the wife wanted to go hike!

Dubs2017 Heres some of that foam you were talking about

Removed the bellhousing, flywheel, clutch, pressure plate and built a little engine crate, I removed the oil pump and made 2x6's work, after seeing the stickers on the oil pan, I knew i didn't wanna ruin it with the weight of a 3F.

 

[huminajumina]

Last bit of effort before hiking, I removed the exhaust, I was able to remove the down pipes without cutting, but the muffler was an aftermarket muffler shop weld in, so I just cut it to get that and the tailpipe out.

Then we went hiking....

More work to come, plenty left, thats for sure! I did a little research over the weekend, but I was limited to cell service and limited time.

 

[huminajumina]

@Dubs2017 @BurntToast @cruisermatt After your guys pulled the dash, did you just separate the harness all the way across from the passenger side firewall to the driver side & remove what you didn’t need? I’ve got everything fished through the firewall but haven’t started up and over yet.

The PO had the H55F swapped in prior to me owning it, so there were a few things hacked from the auto to manual swap. Also the thick white wires I’m assuming are the batter feed wires for sone of the body electronics (similar to the ones off the alternator). Looks like the PO disconnected them most likely from fusible link problems.

Debating if I should figure out how I’ll connect the Alternator & battery feeds prior to pulling them all out.

Any help would be appreciated.

 

[cruisermatt]

we don't do that on our swaps we do here, I don't see a reason to personally. I like the stock schematic to still be relevant
Now repairing hacks and damage back to stock is another story.

 

[BurntToast]

I pulled every engine wire that went to the old ECU that wasn’t reused, but left everything else

That makes a lot of sense, that way it’s not a guessing game later.

Yea that makes sense & just gotta grab the manual & multi meter & filter through what has been modded from the PO.

Thanks a bunch both if ya!!!

Truly it’s all up to your comfort level. I just didn’t like useless wires in the loom.
