I have an 87 firebird formula 350. I decided to replace the tpi with a carburetor..everything worked out great now i have this massive ball of fuel injection wires and i want to simplify my harness. I have the wiring diagram for the tpi in my HANES manual but i need one for a carberated firebird, i dont know what wires i need and the ones i dont need. If anyone can help me out with a diagram or advice I would be so greatful. P.S I dont have the money to buy a painless harness so thats not a option EMAIL: my_lil_fire@rocketmail.com

Hello and welcome aboard.

You should be able to remove the entire passenger side harness, as its only for the fuel injection setup and related sensors. Everything else that needs to be kept should be on the driver side harness. There are definitely pinouts located around the forum here if you do some digging, shouldn't be too hard to find (searching for "bulkhead" should get you in the right direction)
