I have 2004 full size GMC van. I need to find the parking light circuit for light flash output. someone told me it was a brown wire at fuse box under the seat. but there are several small brown wires. And the light switch has 2 BROWN / white wiree, one of which shows +12v when the switch is off and 0v when it is on. Does anyone have any ideas or can you tell me where I could get a schematic?

One of the wires at the switch is it. you need to convert your + output for your rem start to a ground output (either by programing or use a relay) that should work.

Thank you so much. I suspected that it was neg. switching instead of positive . I just wanted to be sure. That's what this site is all about....helping out your fellow man.

Thanks again for responding;

Just use the (-) parking light wire instead at the BCM ( BROWN / WHITE )
