I have dozens of wiring schematics and connector pinouts I made which I'll post up once this thing is running and I verify everything is working.

Here's the progress so far. Made my integration harness which plugs into the LS wiring on one end, and connects to the FJ at the other end on IH1 and IH2.

Next I need to mock it up, do some finishing taping, and loom it.

Nice work, looks really clean !

After quintuple checking all my diagrams, I finished up the last harness for the swap:

Just kidding.

This harness runs from the last one, through the dash, and over to the integration module and DLC connector. Plus a few other doo dads I added.

Finally the wiring is done!

Pro tip - Don't take a multi month long hiatus in the middle of doing wiring. I think I doubled my grey hairs.

Time to move on to fuel.

One of my favorite LS swap builds I've read on any forum. I've LS swapped a few BMW's so I understand the pains of doing the swap, always worth it tho!

Next was installing the second marks4wd adapter plate:

Followed by the output shaft extension:

Next I needed to prepare the 3rd and final adapter. I had to install the dowels into the adapter. I heated the dowel holes to about 400 degrees to make it easier to get the dowels in. I also installed the oil seal into the adapter:

I then drove the brass plug into the hole for the speed sensor. You don't need to use this hole, as the reluctor wheel on the 4l60 is further forward, and you use the speed sensor hole on the 2nd adapter instead:

I then installed the final adapter to the transmission:

What was the cut length after the first Marks adaptor piece was bolted on? I will be getting to this next. Excellent work Sir!

I don't remember what it was, but I believe it's in the instructions from Marks. But that pic shows 132.63mm on my caliper, and I just went and measured that straight edge and it's 37.37mm wide, so 132.63 + 37.37 = 170mm. Math to the rescue!

I am guessing this is running and driving now? Thank you for this thread!

I had thought my journey with my 80 was over but when I told my friend I was selling it I never felt like a bigger POS. This thread has been a beacon of hope.

My drivetrain is now out and sitting in the driveway...
