Hi,

 

 I have been trying my best to strip the wiring harness
down. This is what I've done so far: I went through a Legacy ECU pinout,
and labeled/sepparated every wire that pertained to the ECU. Was this
the correct way to go about it? Now I have a large pile of wires that
didn't directly go to the ECU, and then the four plugs and their
corresponding wires that connect to the ECU. Are these all I will need?
Or did I just make myself a mess...? Also, what is the "Select Monitor Signal"? Necessary?

 

Thanks,

keep everything that hooks to  the engine and ecu , also keep the fuel pump curcuit , and the maim reley, there will be pinouts

from the ecu you wont end up using,

Here is a quick visual of what I have so far.

 

 

 

 

Make sure you don't cut out the yellow wire that feeds to the ignition module and coil, and other 12 v pos. items

Hey dude, look me up and my threads I've done on harnesses. I've prolly asked every question there is about them. Haha. Once you get your head around it, it'll go fast and easy!
