Project 1LO MZDA wiring question

So I was removing the ECM wiring harness. I know that the wiper motor wires have to stay but what are the other wires in the harness that go through the firewall? Also, how many of the sensor wires that are in with the headlight bundle have to stay? What about the fuse block? Is all I need the main 80A fuse or do I need the two 30A fuses also? I have a weber on it now. Thanks in advance.

are you removing emissions stuff if so everything except the wiper stuff can safely go...

Fuse block has to stay. You have 2 harnesses coming out of the cab. The one on the left is the ecu and emissions. That one can go. Except the wires to the blower motor. The other harness on the right you need to keep. Thats where your block is tied into. It wraps around the radiator support to the left side.

Yes, all the emissions stuff is gone. I'm keeping the canister but that should not affect wiring.
So there are the wiper motor wires AND blower motor wires in the same bundle on the passenger side, correct? The 2nd bundle of wires going through that hole appear to go towards the center of the dash. Are the blower motor wires in there?
I know the drivers side bundle has to stay but there are a bunch of sensor thingys at the end of the run after the headlights, turn signals, and markers. Can I just clip those or what? I still am unsure about the fuse block. Thanks for the help so far.

Oh, and hunterw, your truck in the pic is BAD ASS!!

I also wonder this^ I'm in the process of getting rid of my excess wiring

I also noticed that there is a wire coming from the trans. What is that and do I need it? It's a 5 speed.

Anyone have any ideas?

You might want to keep that one if you want lights when you're in reverse!

Ah!! Yes I would! Thank you very much.
