Started out as a good toy but after a few months of driving it the 3.0 went kaput. So it has been on the back burner for about a year or so and I found a low mile 97 t100 and decided to bring the runner back to life. I am doing the 3.4 swap on my 88 manual 3.0 4runner, I bought 97 2wd t100 with auto and then I found a 97 t100 4x4 manual ecu. My problem is finding all the ends for the ecu so I can repin the auto harness for manual ecu. Does any one have suggestions on plug ends? I found the 22 pin at toyota but I still need the 26 pin, 16 pin, 12 pin. Any help would be appreciated!

Thanks, I have gotten lost trying to read what I think will help and this gives me a go back to point. After I read so much I get CRS

Thats good information! I didn't have the 88 diagrams yet, Thanks

 

I got the harness ends from the stealership, they charged me ten bucks a piece for them after they quoted me 7. Guess I will be looking for another source for OEM parts!
