Question regarding brake lights
I am about finished with my conversion project( Taking a '99 FRC and doing a complete Z06 conversion) and now I can't get the four brake lights to work. The third brake light lights up fine. I have turn signals and hazards. The bulbs are good and I have checked fuse 8 and 15 in the footwell and they are fine. Any other ideas?

With the brake pedal depressed: 12 volts at pin A(dark green wire), and check resistance to ground on pin G (black wire).

Look under at the brake pedal area and see if the white wire is cut. I can't remember if that car came with the euro lights.

That method may give you a false result if you have a bad ground. So what's best, is to make sure the black wire is a good ground, with reference to the chassis...should be 0(or very low) ohms. If you have a good ground at the connector, then you can test for 12 volts like you described with confidence.
Red lead - dark green wire- pin A
Black lead - black wire - Pin G

Hey Tony, turns out the wire was cut so thank goodness for an easy fix. Thanks for the help guys! Everything works as it should now. I just need to figure out why I don't have low beams on my Depos that has HIDS? Any ideas? Could be the bulbs, but both being burned out at the same time make me question that.

I bet the ballast wires are backwards. A lot of the china stuff have the positive and negative wires backwards. Flip the connector around and see if that works.
Glad I saw your post about the brake lights. Could not remember for sure if that one had the euro lights or not since there have 6 vettes that have passed through here over the last few years.
