Anyone knows where i can find a wiring diagram for the wires that goes to the fusebox, the big one to the right is from the 1J harness and the 4 connectors the the left are from the 7M. 7M has 16 wires but the 1J only has 12..

This purple wire from the 7M harness cant find a home on the 1J harness

Here are some wires left over, is it just to cut them since they are for cat temp sensor, egt temp sensor and for the digital dash that is on some JZA70.

Those first two big wires connect from the alternator to the black wires in the fusebox area which used to go to the ring terminal on the 7m alternator.

The colors for those power steering wires look right. Dunno about the ABS.

That big connector on the 1jz harness is EA2, there are wiring diagrams for that available, I'm at work at the moment and can't get a link for you, but i'll put it up if someone else hasn't when I get home.

Yes. They need to make their way over to the driver side of the engine bay. You will find the two black grounds coming out near the fuse box. These went to the original 7M alternator.

These red/yellow wires goes to the gearbox?

Yes, they are for the reverse switch.

I don't know what that wire is for either. I left it disconnected.

Yes, cut them/leave them disconnected.

Just want to clarify something, those thick black wires near the fusebox are not grounds.
