bought a 94 3.0 2wd auto 4runner back in July ran it a couple months then blew up the motor. When I pulled the motor I decided to make it a 4wd 5 speed using my old 93 pickup for parts along with the 3.0 in the truck . I welded in the 4wd drive mounts put the motor and tranny in then I stopped working on it. I bought 2 98 4runner's and used some body parts off one to fix the other. I still have the complete motor and wiring harness and was thinking about pulling the 3.0 out of my 94 and dropping the 3.4 in. I want to do all the wiring myself and can't find diagrams could someone help me with wiring? Also have a stupid question about the exhaust. Could I use the driver side manifold off the 3.0 on the 3.4 and eliminate the crossover and run the headers down to a y pipe. Any help on this swap would be appreciated. Could use all the help I can get.

Read the stickies before you go any further and no you can't use 3.0 manifold on 3.4 they are different heads.

 

EWDs can be found here (pay the $15 for 48 hour access, pricing could have changed in the last few years):

If you're not going to spend the time reading through other swaps and the dozens of threads dealing with the wiring, just go buy a harness

No.

Read the stickies (the threads "stuck" at the top of this section https://www.yotatech.com/f160 ), read through various other, older swap threads, unfortunately a lot of the really good ones have lost their pictures but the text information is still there. Of particular note, read Elvota's swap thread (it's a sticky).
