Yotatech you're my last hope! Does any one on here experience swapping from a 3.0 to the 3.4 (WIRING)... Im down to 2 plugs, IH2 and IH1 off the 3.0 harness and II1 and II3 from the 96 harness. The II1 and II3 wires need to be spliced to those on the IH1 and IH2 to be finished. Cannot not figure this out at all have looked over countless wiring diagrams, posts online can't seem to find an answer...

For reference my truck is an 89 Toyota 4runner 3.0 manual trans and the donor truck was a 96 Toyota 4runner 3.4 automatic transmission.

Help!!!

P.S. I have the wiring diagram from techinfo Toyota for both trucks can't seem to figure it out

 

PM me your diagrams from tech info and I'll try help you out as much as possible. I hope you download all of them.

 

you must be reading into it too much. de-pin both the IH and II plugs. then use the plugs that match your truck dash harness. use the drawings to match the signals needed.
