My car is a 1991 Firebird originally a 305 TBI car. A good number of years ago I swapped in a 350 TPI and engine harness from a 1989 GTA. I sent the engine harness out to a company to convert the GTA harness to a speed density system. They did what I needed them to do and I've had no major issues. They kept the 89 fuel pump relay pack con connector and I am upgrading to Delphi style. On the pack con the terminals are labeled ABCDE and on the Delphi their labeled ACDEF. Do you know if A on the pack con is A on the Delhi? C is C? D is ? E is E? Does that make B is F? Another thing that is tripping me up is the a color change on one wire on the drawing for the 89 and on the 91 drawing. The one wire that is different is on the 89 drawing a tan w/white stripe is a grey wire on the 91 drawing.
Any insight would be helpful.
