I have a flash2pass garage door opener that I would like to install on my 2017 Volt.
Super simple - just tap into a ground wire and the high beam wire.
Momentary double flashing of the brights triggers the door opener.

Problem - Unlike the car I traded in on my Volt, the Volt has one multi-wire harness for all of the bulbs in the left and right assemblies. (at least I've only found one harness)
I'd prefer not having to jab each wire with a needle while someone toggles the high beams on and off if possible - so if anyone already knows the wire color - I'd appreciate it.

On gen 1 Volts it's white. Best guess is it's the same for gen 2.

Finally got around to installing it this afternoon - hooked it to the solid white wire and one of the black wires - and it worked perfect!
Thanks for saving me from having to poke a bunch of wires to find it.

Glad it helped.
