I got mine yesterday and had fun seeing what all showed up on my 4 Toyota’s

Not sure if you saw my other post, the way the OEM harness works is not a traditional power and ground. Both wires have positive DC power with the lights off. I just measured mine for you Battery voltage at center pin and 9.5VDC at the outer pin when lights off. Battery voltage at center pin and 3VDC at outer pin when lights are on, voltage fades up and down and lights turn off and on.I did do some checking and I have a constant 12v on the center pin of the connector when using a known good ground on the chassis. I saw in the manual that the outside mirror lights are tied into that circuit too and those can be enabled by the Toyota. My LC is a 1958 so I am pretty certain that all that is not enabled. The manual says on by default then it has a little note that says if equipped.
What missing on yours? Did you ever get a chance to check the other wire for voltage to ground? The one has constant 12VDC but the other isn't a ground as it has 9-3VDC depending upon lights on or off (approach/door open) for the step lights.After looking through this list some of these setting are not available on all models. I have a 1958 model and some of these exterior light options are not listed when I connect mine up.
Yep mine never reads any voltage on either pin other than the center. I even took one of the connectors and wired up the rock light I was going to use and nothing.What missing on yours?
