No. Hook up the power wire first, then the ground wire. The ground wire is what acutually draws the power to the unit. As you will notice the power wont turn on if just the power wire is plugged in..

1979 ford f100 fuel tank theres a green wire and a black wire where does the black wire go the green wire is hooked up but not the black one?
One wire goes to the sending unit in the tank. It should hook to a terminal beside where the fuel line connects. The other one grounds out the body of the sending unit or the whole plate where the fuel line goes into the tank. 3-4 inch round plate. The ground wire will either go into the wire harness with the sending unit one or ground directly to the frame. The ground wire on all gas tanks very often rusts off.

How do you bypass the parking brake by grounding wires?
on my older jvc its no problem at all just ground the wire that your radio says to hook up to the ebrake. newer ones and like my pioneer need to have the radio turned on first then ground that wire. trick is --- get a standard universal relay--- like from autozone for your aftermarket driving/fog lights. take the 85 terminal of your relay and hook it to your radios power amplifier wire(usually blue with white stripe), take the 86 terminal and hook it to ground. take the 87 terminal and hook to the same ground, and finally take the 30 terminal and hook it to you radios ebrake wire. simple :-)

Where do you hook a ground wire up for a car radio?
There should be a black ground wire in the Chevy Celebrity radio wiring harness. If for whatever reason that is not available then simply hook a wire from the metal shell of the radio to a convenient point on the dashboard near the radio. I would use a convenient bolt or screw if at all possible.

How do you troubleshoot oil sending unit?
Un hook the wire going to it , and ground it with the key on and it should go all the way over to highest point. If it does that means the gauge is good. Replace oil sending unit. You can also screew a gauge in its place and read oil preesure. ( remove oil sending unit)
