The thing is ,if its not getting a good ground ,most likely your lights will not be working, I wouldn't think . You did say all the lights are working ?? When the brakes are pressed are you getting the 12 volts or whatever to the plug on your truck, you may have mentioned you checked that ,and I missed it .
Correct. All lights work - have checked everything. When brakes are pressed, I'm not getting 12V to those two pins, but as it was mentioned above, unless there's a load detected, truck may not be sending full voltage anyway so that may be a bad way to check.
