Red face Courtesy light switch

Does anyone know which wires to put a momentary switch in to make the parking lights flash off (courtesy flash) like the big rigs? I want the parking/marker lights to go off when I push the switch and come back on when I let off the switch, all without disturbing the headlights/fog lights. BTW I have an 04 F-350.
Thanks.

look at the back of the headlight where the wires go in for the parking/turn signal

I'm looking at an '05 schematic, but I think it will be the same on an '04. Not positive.

The wire color is brown, and it goes to tail markers, overhead clearance lights, mirror markers, everything. You will have to find the segment you want to interrupt. If you want to interrupt all of them, then the brown wire originates from the VSM on under the left side of the dash.

Question

Would the color of the wire and location be the same for a 2003? I am thinking of doing the same to my truck. also I have to ask what does "VSM" stand for??

VSM = Vehicle Security Module, I had to look it up too.

Here is a schematic page for the lamps circuit:
http://www.billpounds.com/truck/Exte...psCircuit1.pdf

I have no idea if this will be correct for an '03 - '04. I'm reasonably sure the wire color will be brown on all of them back to at least '99. But the way the VSM is wired in, and particulalry the VSM location, may well be different.

Anyway, I hope this helps.
