My underdash wiring is a bit of a mess. There are a couple that i am unsure of. The first is a fried Black/Purple stripe that attaches to a single female terminal with a brown attached. The second is a yellow/grey/black with a black plug. The yellow is spliced into a light blue wire with a white bulb socket and the grey and black are cut and taped.
Any help is appreciated,thanks

what year? guages?

The more info you give when asking a question like this the better other will be able to assist you.

OOps ..first post
Its a 1970 SS auto, No AC and with factory gauges. Doing a search here i have figured out the brown and black/purple (AC,TCS) I still havnt found anything on the 3 wire plug though
Thanks

Yellow/black/grey is the radio plug - yellow is power from the radio fuse, black is ground and grey is for dash lights.

The burned, black/pink (may look purple but it's pink) wire is the TCS power feed. On 70 TCS gets power through the 25 A A/C fuse, when the underhood wire becomes grounded/shorted the insulation melts before the fuse blows. The brown wire is the A/C power feed, not used on non A/C cars.
