Wiring Question...

[05_PwrStk_Noob]

Does anyone know if there's a list somewhere where you can find out what all the SEIC/CASC wires(about 12 wires with black ends) that come through the firewall behind the in-cab fuse panel are for....there's a white "tape" tag that looks like it MAY have had something printed on it at one time....i used one of these wires(following online instructions!) for my "high idle mod" going to upfitter switch #3, but i was just curious what all the OTHER wires are for...useable or not...
I imagine they're all to do with pto use(?), which i don't have anyway. I just can't find anything that tells you what the wires ARE.
Thanks for the help!

There is a section called "Tech Files" that has all kinds of info about your truck.

Here is the Tech File for hooking up the High Idle Mod: Engine Idle Mod (How To With Pics)
