Hi there everyone I just bought an 87 350 tpi and after 13 years of sitting I managed to get it turned over. However I'm running into an issue with the fuel pump not coming on. I've traced multiple broken and mouse chewed wires and am pretty confident I got all but three wired up right. These three come out of the circular grommet on the passenger side just above the main harness. One is green. One white and the other is black. Does anyone know what these wires belong too?

 

Those belong to your power antenna , and won't help you with your fuel pump issue ...

 

Does your SES light in the dash come on? If not, then check the fuses on the passenger's side frame rail... If the fuses are good then there is a chance the splice in the wire near the blower case has come apart...

 

The dash is out of an 84. Not sure why it didn't have the original but would that light still come on with a different dash?
