Toyota wiring manual
I just finished putting a Calif. emmissions eng. 7A-FE that had an A/T on it, into a FED-Canada car having a 7A-FE and M/T in it. Both cars are '93 DX models.
The Calif. eng has EGR valve and the Fed-Canada did not. I initally left existing computer, and exhaust system in the good car and it ran OK, but thought it would not pass smog test so replaced computer, exhaust system and wiring harness with the parts that came with that good engine I installed.
The dashboard plug that goes into the computer had a 12 pin plug and the puter has a 22 pin socket.
I asked an auto electrical shop to make me a wiring diagram to make the different wiring work. He had to buy a wiring book from Toyota. But after studying the Haynes and Chilton wiring diagrams, I figured that matching the wire color codes for the two plugs would do the trick and it did. There are now 4 extra wires not connected but they were for the A/T I think.
Will ask shop to check my modification to be sure I don't ruin my puter.
If you still need wiring info I can give you the electrical mechanic's address and maybe he can make up a diagram for your particular situation.
