Electrical , where does these wires go

[twoskies]

Good Afternoon and Happy Holidays to all

ive got a small bundle of wires coming out of firewall right to upper right of factory square plug, i got in a hurry taking doghouse off and did not label, these dont show on the wiring schematic unless im looking at it wrong
i have looked through forum and might be TCS wiring, again dont know

red wire(looks pink)
,black and white wire, green and black/white wire has a blue wire all together attached to it(looks like an alternator plug)and a brown wire that loops up to the tray and goes into a rectangular clip
its hooked up
other wires are not
if it is TCS, do i need to hookup or just tie together and leave alone



Any help appreciated
Thank You

Look above the fuse block on the inside of the firewall. The big red wire probably goes to a relay that looks like the horn relay. If that's the case, it's the TCS relay and you really don't need to do anything with it.

3rd pic down is for the brake. Use the schematics in the electrical section. Some of that looks not stock to our trucks.

Thank You for your responses, the 3rd picture does show a connector that looks like the brake connector but its not, its coming off the engine wiring block harness and hooked up

Thanks

Thank You Truckster

it is hooked up to a small box that looks like a horn relay, it was already disconnected from power, i coiled up the wires and wire tied them up
kind of odd i would have the tcs system on my truck, its a factory 4 speed, i thought the tcs was only for automatics

Thanks
