I hope some people can make some use of the diagrams I have been collecting. I am not sure why these are not easier to find or in one place, so maybe this will help.

I got a message from my mechanic where my car is while the swap is being done. He is having trouble with the wiring. I need wiring diagrams from the 1jzgte to a 1uzfe fuse box. I offered to purchase a 1jz box or a 2jzge box. I want to make this easy for him as I understand how frustrating the wiring can be. If anyone has a wiring diagram of the 1uzfe, I would appreciate it. I may already have it, I just need to weed through all the diagrams I have been collecting from various sources and speak to him to see what he needs exactly.

I will archive these, so if anything happens to this thread, PM me and I will get you what I've got.

Enjoy!

I Love You Man, THIS HAVE TO BE STICKY

I'm confused why do you need to change out your fusebox? is your car a sc4?

i have an extra one, it came with my 1jz swap. let me know if you still need it. all fuses are there and the cover is there too.

sorry, just looked at the fuse box picture of the 1u, and it looks the same as the sc300. Are the plugs not matching?

I am not sure if we need to yet, but if it would make it easier, I would do it. I have not gotten a chance to see the problem yet. My car is at my mechanics shop and I am only going by a few short messages he left for me.

"I'm having problems with wiring. We need a good wire diagram to the fuse block under hood. motor wont hook up to it and it did not have a plug its cut wires." - That was the first message I got from him indicating he was having a problem with the wiring.

That's a hard question to answer actually I did the vehicle history report on the car and it was listed as an SC300, but the guy I bought it from attempted (I don't know why) to swap a 1uzfe v8 into the 300. He has major problems doing it and sold me the car for CHEAP. I didn't really care since I wanted the 1jzgte right away anyway.

In the message he left, he said the plugs were cut, so I guess (since the fuse box pics are identical) that must be the problem.

I'll update when I actually talk to him about it. If anyone has some (constructive) comments, I am all ears/eyes.

And thank you ^^^^^ for taking the time to respond. I hope the diagrams help someone going through a similar problem.

You dont have to touch the fusebox for the swap all the wires are on the passanger side kick panel
