Usually goes from the negative post to the engine block. Another one goes from the engine block to the car frame or body. Real easy to find, just trace from negative post of the battery.
I NEED TO KNOW THE GROUND WIRE IS IN THE WIRING HARNESS UNDER DASH.
OR DO YOU KNOW WHAT WOULD MAKE MY SPEEDOMETER, TACH AND TEMP GAUGE NOT WORK ON A 1988 T-BIRD COUPE?
The constant power wire for the radio in a 1990 Ford Thunderbird should be green/yellow. The ground wire for this vehicle's stereo system should be black/light green.

Usually on the Negative terminal of the battery.

Jumper wire from Battery + to Coil+Jump starter solenoid from smaller trigger terminal to starter side
Just ground the wire with a screw straight on to the frame!
Somebody please answer this i am also having a problem. if i wire the aftermarket radio it does not even power on. but if i put the stock radio back in it works. could this be a problem with the ground? Help!
the bronco needs to have the ground wire connected from the battery to the body. if you replaced the battery and disconnected that ground it simply won't start.
positive wire is the live wire it goes to the + term ground goes to - term
It is the ground wire for the fuel pump. The Red wire is the power wire for the pump. the dark blue is the signal wire for the gauge and the black is the ground for the gauge.
its bolted to the block.. just follow the cord its not hard...
This could because by a bad ground wire. Check the ground wire to make sure it is connected properly and not corroded.
