Hi everyone, I have an '84 GMC 6.2l diesel that is a really great/tough truck.... but... the high idle wires are disconnected from the switch (just a toggle switch in the lower dash) I can trace the wire from the solenoid through the firewall to the switch, but no idea what the other terminal on the switch should go to... a power source? I am scared to go ahead with trial and error as I don't know what the consequences could be. Anyone know how to wire this back up as it is getting a mighty cold up here in Alberta, Canada. brrrrrr!
Thanks
Thanks
