DML FAQ : Electronics : How can I have my foglights on with my high beams?
There are 2 connectors. A 2-wire connector and a multi-wire connector. The 2 wire connector has a BLACK and a BLACK with GREEN STRIPE wire. Run a jumper from the BLACK with GREEN STRIPE wire in the 2 wire connector to the LIGHT BLUE with BLACK stripe wire on the multi-wire connector. That's it! Your fog lights will come on when you turn them on (parking lamps must be on, at least) and will stay on with low or high beams.
