Been looking through threads trying to find tips on putting an IR light on my A2 but haven't been very successful. Need recommendations on location, wiring, etc. I was looking at putting is on the bumper between the headlight and turn signal and then using the wiring from the blackout driving light (rerouted). Thought the dual connectors on the back were + and - but cracked it open and discovered that the ground is the post. Any thoughts would be appreciated! THanks in advance!
