Trying to add some courtesy lights to my 2004 and found this:



<TABLE style="WIDTH: 349pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=466 border=0 x:str>
<COLGROUP>
<COL style="WIDTH: 87pt; mso-width-source: userset; mso-width-alt: 4242" width=116>

<COL style="WIDTH: 62pt; mso-width-source: userset; mso-width-alt: 3035" width=83>

<TR style="HEIGHT: 12.75pt" height=17>

Looks like it'll work but I hate to add door pin switches when I know there must be some in place already, and it looks clean.


Does anyone have any experience with, or details on how to tap into the 2004 D/A door switches? I cannot find them anywhere in the door jambs, but I know they must exist since the lights come on when I open the doors.


Or is this like the magic refrigerator monkey, that turns the light on and off just when you open/close the fridge door? If it is, where IS the monkey located in the 2004 GM? http://www.dieselplace.com/forum/smileys/Confused.gif

The door switches are integrated into the door latches. You came tap into the courtesy light supply voltage at the BCM, it's a gray/black wire on connection c5.


Hope this saves you some time...

Thank you BlueOx03. I hate to ask, but what *is* a BCM and where is it located on the trucks? I've heard the term before but I've not yet taken the time to figure out what it means.

The BCM is the Body Control Module it controls all the lights and stuff. Look under the dash, straight under the steering column. There's a box with 5 plugs in it facing you. The wire you're looking for is in the plug all the way to the right.
