I did the upfitter switch and harness install, and hooked up the BCP mod for the fast idle. My question is what are all those other wires for that are bundled up with the one (purple with light blue stripe) that I used?

I know that there are four pass through wires for my (customer) benefit or use (black, red, white and dark blue), there is the one I used for the BCP mod, and the solid orange one is for the SEIC mod. I also believe that there is one there for the SEIC indicator light, should one choose to use that. That still leaves four or five other wires.

Can anyone tell me what they are for?

Thanks.
