why didnt you just ask me???? and what happened to the diagram i sent you? OK the head lights and the parking lights AT the switch are both on the same wire [white with a brown stripe] and it is looking for a ground-BUT here is were it get's stupid. if you ground the wire it wont do any thing-BUT IF YOU GROUND IT WITH A 1670k RESISTOR IN LINE it will trigger the headlights and using a 1200k will trigger the parking lights. whats the plans NOW???? make sure that what ever your up to you must use a relay to trigger that wire or it can feed back to it's source and make the head lights and park light stay on all the time -the length of the wire it self can become a resistor it and keep the lights on-SO what you do is use a 30 amp relay and ground pin 87 then pin 86 goes to power then pin 85 is use as a ground trigger to work the relay threw a switch are what ever you have up your sleave-and then pin 30 goes out to the light wire with the resistor no more then a couple of inches from the switch. and try not to blow up the neighbor hood
First check the nova website to see if its compatible with your car. Sometimes there is a function of the computer that monitors the headlights and if it sees power (or ground) pulsing on the line the computer thinks that there is a problem with the bulb and cuts off power to that light. I had all sorts of problems getting a generic flasher to work on a dodge P/U, and i ended up having to get a specially deigned flasher.
Personally i have never tried it on a charger because I'm too chicken to go cutting stuff.
