Where does the tach wire come through the firewall i can't locate mine. A picture would be great. That wire should go to the negative side of the coil right ?? I may need a new harness

Lower wire on the male spade is gray with a pink tracer.

Nora can you tell me which side in the rear of the the fuel gauge would i put power to to test the garage? If I'm sitting in the car looking at the gauge would it be the drivers side or passenger side post in the rear. THANKS

Whoa. DO NOT PUT POWER. If you want to see if the gauge moves you need to ground the terminal i circled. You had better be careful as I see a smoke filled car in your future.
 
I was gonna test it on a bench out of the car i put a new sending unit in and the gauge is only moving little bit i have at least half a tank. Have a New sender and I'm getting a pulsing power to the sender terminal wire. I also grounded the sending unit at the sender plug and gauge didn't move which i thought meant the gauge is the problem ?/
