Re: 68 C10 Yellow wire from firewall to starter/coil.
12 volt with key on:
Easiest: replace the points distributor coil resistor wire at the firewall connector. That wire will then have 12V. http://67-72chevytrucks.com/vboard/s...d.php?t=708975
Easy: connect to one of the IGN UNFUSED terminals on the fuse block. If you need that 12V with key on in the engine compartment, you should run the wire through a hole in the firewall with a grommet. Info on fuse block: http://67-72chevytrucks.com/vboard/s...d.php?t=741245
