I am going to be installing a light control head that can be dimmed via the trucks interior light dimmer swtich. Does anyone know which line I should be tapping into and the best access point? I will be using a Whelen MPC01 controller if that helps.
Thanks.

Most GMs have a 5A fuse in the interior fuse panel that is dedicated to the dimmer circuit- and yes, the fuse is on the variable voltage line. There are also many GMs with a tap in the fuse box marked "int" or "inst" that is where you need to go. If all else fails, pull the 0-12V from the lamp in the ashtray.

Most vehicles have a panel light for the ashtray. The ashtray is already fused and located in the center of the vehicle. T-tap off the panel light hot, usually orange or yellow. The other wire going to the light is usually black (ground).
