I have three problems after my pioneer install.
1) my fog light/trunk switch module doesn't work. No current is present from the wires.
2) gas cap lid switch doesn't work. no current from the wires on the switch end.
Some questions, if the relays for the respective switches from 1 and 2 above are "bad" will that cause them not to work. How does a relay go bad and how do I check them?
