wiring problems

[Keith Bradley]

I have a 1985 chevy c10,305 with a th350c with a lockup touque converter and it has a/c. There are 7 wires that come through the firewall from behind the heater box. They all had been previously cut off by the former owner in the engine compartment. Can anyone tell me were these wires go and were they come from. Can not find them in a wire diagram. Colors are brown, green, blue, light brown or salmon, black, and 2 yellow

The wires are for the blower and the ac.

Found out the wires were for. Electronic spark control distributor. Former owner must have changed distributor and cut the wires off.
