Recently picked up an Elite 2500 and an Elite 2500 Universal harness and I'm trying to find a wiring diagram for the FD as a jumping off point. There's obviously more wires than I need, but I'd like to see someone else's pin out to get a general idea of where to start.

Really looking forward to this upgrade from my PowerFC and I think a weekend or two of building a new harness will definitely be worth it.

 

if i were you, i'd start with the wiring guide for the Elite FD Plug & Play adapter to get an idea of what wires go to what. keeping in mind that adapter is wired for stock ignition so if you are using IGN1-A coils or similar you'll need different coil wiring.

the yellow chassis plug near the factory ECU/kick panel is where you'll find your connections like speedo input, clutch switch, etc. those are listed on this diagram with pin #'s and also in the image below with wire colors (connector #1)

Thanks! I'll definitely start by comparing the off-the-shelf adapter with what I want to have in the car. My biggest concern is removing wires that I might need down the road.

 

There is this gem too.
