3VZE to 3.4 swap wiring problems
 

I am having some problems splicing in the wires from a 3.4 swap, some guy started this swap and did most of it but stopped after he got paid, so now it was brought to the shop i work at and the speedo, tach, oil pressure, and temp gauages all don't work and i have the wiring diagrams but it is taking forever. Does anyone know of a chart someone have made that simply shows what wire colors form each side line up? It is a 1994 4runner, a 96 tacoma engine and it also has a 1999 tacoma rear axle. The back up lights don't work either but it is missing a connector, and the temp censor connector was just hanging there with no where to plug it into. Help please if at all possible i dont want to have to charge the customer hours of labor if i don't have to thanks

Plenty of info in the 3.4 swap forum
 

You will need the EWD's for both the donor and the receipient. You can get a them here at the TIS site. It's like 10-15 bucks if I remember (well worth it). Every swap is different so you are going to have to do the homework.

I have done a wiring theory thread with some docs that will help you out tremendously.
