Cut wires

[sparky69]

Does anybody know where these wires go? Its red, blue, black, and a splice off the brown and white.
They go to some relay inside the cab. Here is some pics to clarify.

Ooops I seem to can't put any pics in here. Anyway I can e-mail someone pics if they need it.

These wires goes through the firewall separete from thr regular harness. Its a 72 c10.

Any help would be apriciated.

Thanks, Adrian

I'm gonna watch a movie, be back in a little while
