New edge 6.0 wiring Ok just wanna get an idea of what I can and can't get rid of for wiring..i plan on using the ms3 gold plug and play harness and computer to run the engine..and I still want to use factory gauges so I'm gonna keep the factory computer..i will have the fans on a switch and fuel pump on a switch..so can I get rid of the ccrm? And is there anything else I can get rid of in the factory harness to clean it up and anything that I for sure need to keep?

MS3 Gold has trigger wires too, so you don't need to put a switch for fans and fuel pump. CCRM controls fans and fuel pump, so yes eliminate that. When you unwire the fuel pump in the power distribution box, remember ford PCM supplies ground to trigger and you will be supplying voltage. IIRC ford vss signal is different than GM, So speedometer may be an issue. It really depends on how far you go with the Megasquirt(controlling engine only to running trans and other things).

In the factory Ls harness it's the big purple wire that goes to the solenoid. Since you are not controlling the trans, have you looked at Microsquirt V3 if you just want engine control? I know its batch fire, wasted spark and comes in plug n play too. It's a lot cheaper, but doesn't have IAC control. You can tune for that though.
Starter relay and EEC relay is located in the power distribution box under the hood. Since your Mustang should have PATS you will need to keep the PCM or rewire the ignition if eliminating it.

Yes it does IIRC. Denmah(Matt) ran one on his turbo Fairmont. He would be the one to ask. He even messed with the MS3 gold.
