Today I went through the wiring diagrams in the manual that the ex-ford dealer is letting me barrow. it turns out that pretty much everything on this particular harness is needed accept for a couple minor plugs that I can hide. So I am not going to hack it up.
This is the harness that connects the engine harness to the ECU. It has 3 plugs that are under the dash where the computer is. 2 are for the dash harnesses and 1 goes to the rear of the car for the fuel pump. I will use the fuel pump harness and just modify it at the pump end instead of rigging something up to work. Because the dash harness plugs are hidden under the dash board there is no need to cut them out.
The modual in the pic is the CCRM and is needed for the fuel pump and fan and some other items that are needed.
The plug connecter with the bracket and the smaller one next to it are for the engine harness. There is also another engine harness plug on there that is a bit smaller.
Then it has the plugs that connect to to the 2 fuse boxes, a ground plug, a plug for the cooling fan, those are all needed.
The ones I don't need are for the A/C and the headlights/fog lights. We decided not removing the A/C plugs just in case we wanted later on to add the A/C. The headlight/fog light wiring I can just cat back. So this harness will stay pretty much intact.
