I recently installed a new light circuit harness under the hood on my 79 C10 Custom Deluxe and it has connections for two horns. However, I have only one horn. Can anyone tell me if two horns were standard on all 79's or did some have only one horn? thanks Curtis Wells
Did it solve you gauge problem. I have the same issue right now with my 79 c10, 250 6 cylinder. New gauge and large sensor, but gauge barely gets past C. I have not changed the TS 135
Can I use a modern auto relay-30 amp, 5 pin- in place of the original GM relay on my 79 C-10 for the blower motor circuit? Way, way cheaper than an original replacement style.
