I was wondering if anyone is good on the tis Toyota site. Aka Techinfo.toyota. Anyway I can't seem to find the pinouts on the tis website for the body pluGS. I have a 1995 3.0 that I swapped a 1996 3.4 into there both 4runners and I can't seem to find anywhere the wire functions of the plugs that I need to make the swap work. I think the plugs are called ii1and ii3 on the 3.4. And ih1 and ih2 on the 3.0. Anyways any help would be greatly appreciated. I have been reading this form for about 2 months now and still can't seem to find exactly what I need.

I am just starting my 3.0 to 3.4 swap out of a 99 4-runner to 88 4-runner. I have donor vehicle and wiring harness so wiring shouldn't be too bad. I am also swapping out the left hand front Diff to the 88. Got that done last night and now some gas line work. I am using engine, tranny, transfer case, rear diff and front diff out of 99. I am leaving my exhaust on the right side. The 99 only had 30,000 miles on it. I am looking forward to getting some advice from this forum on some small problems I may have. One problem I have is fuel pump. I hear that the 3.0 pump will work and others say it wont work. Anyone know the real story on this. Oh, in order to get the front CV shafts to work I had to swap ends on CV shaft from 88 to 99 on diff side. It worked perfect and the shafts look and line up correctly. Have a good one!!!!
