Hello all! Just joined the forum as I am acquiring a 91 firebird formula. It has been sitting in a yard for about 20 years. Main reason I am interested in getting this car is because there is documentation on this car saying it is 1 of about 100. I think one of the main problems I am going to have is finding an engine harness for the 350 TPI. Everything to the car is there but the wires have been chewed on from mice sitting outside so long. I am wondering if the harness is the same as one out of an 87 TA 350 TPI or vette of same generation with with same motor. Any help is appreciated. Thanks

 

You will need a harness from a 90-92 bird, might want to post in the classifieds wanted section.
305 automatic is the same harness.

 

Awesome! Thank you. These things are hard to find now days.

 

Is the Camaro harness the same?

 

The camaro harness will work but you have to lengthen a few wires since the battery is on the opposite side of the car. Ccp, fan and ecm/fuel pump power iirc.
