I have 89 Trans AM 305 with auto trans. It is in the process of being rebuilt and has been through couple of shops. The wiring has been cut in many places during the build and is old and frail. I was looking to look at options to either completely replace it with a new reproduction set (not sure if it is available?) or a universal Kit. Is there complete wiring diagram available for this model that could be used as a reference? The engine has been replaced with 383 stroker with carb intake and 5 speed trans.
I would appreciate all the feedbacks.

 

Fsm or Austin thirdgen has the schematics. Doesn’t really matter if you’re ripping out the tpi harness.

 

Listen to Tuned Performance, Factory Service manual is suggested first for a reason, online schematics are great but having a large print out in your face with the various connectors will let you catch issues. You also get the factory diagnostic trees for electrical which is an absolutely incredibly resource.
