So I recently done away with the DRL's on my truck as some know. I'm looking to put some light bars on that circuit to replace the loss of DRL's, so, two small LED bars as DRL's mounted in the bumper.
My concern isn't the current capability of the circuit necessarily.
My concern/question is... Could I tap in to the DRL trigger coming out of the BCM that heads to the relay to trigger that circut with +12v or ground (whatever it needs) for night use of the bars? The concern is that applying power or ground to a control of the BCM without it saying so or knowing will damage the board. In my mind it should do nothing, the circuit is off and only runs the DRL's as far as I know. I just don't wanna fry my BCM
Basically I want to run a switch to said control wire. Switch off = normal DRL-like function. Switch on = DRL control override ; always on.
