chevy cruze parking lights

Quick question. Testing the negative parking light trigger on a 2012 Chevy Cruze. It appears to rest at about 10-12v and go to ground when the lights are activated. Is this the correct wire to trigger with the negative RS output. It's the GREEN/ grey wire, pin 22 of the white BCM connector. FWIW, I'm installing a CM7200s with a Blade-AL. Thanks!

sounds like you're on the right wire, when you say goes to ground, you mean meter reads 0.00 volts correct? you could also put your positive meter lead to one of the RED / striped wires at the bcm and your negative lead to suspect wire then voltage should read opposite, zero parking lights off and 12volts lights onAdvanced

Correct. Positive lead off my DMM is connected to power and the negative lead is connected to the suspect wire. At rest it's testing 10-12v(parking lights off) and with the parking light on it shows 0 voltage. Thanks for the reply!
