I am running an alpine radio that has a dimmer function wire. It hooks somewhere, I assume, into the headlight switch. This should allow the radio illumination to match the dash light illumination when the headlight switch is pulled on. I know the headlight switch has a rheostat that controls the light output for the dash but the switch itself has multiple poles off of it and i have no idea if one of them is responsible for what im looking for.
Anyone have any ideas? the wire diagrams i have in the hayes manual are very small and don't really help please and thank you |

Grab your DVM and ground the negative test lead, then put the positive lead on each of the power out leads of the switch. (not the bigger power lead into the switch) See which output lead varies voltage when using the dimming function of the switch. That's likely the lead you want to tap into. Slide the radio lead into the connector and double check radio illumination function.
