have a 94 lt1 camaro automatic
whats the bare minimum on the body/dash harness I can shave off? deleted my ac box, while im waiting for the plate to ship how much of all the crap on the dash can I delete? theres a lot of relays throughout I haven't gotten to find out what they control, the silver box next to the steering wheel can I remove? seems to be apart of the air bag system which I also deleted
also what can I do with the under hood relay box? I want to relocate the two injector fuses
just plan on having the cluster work, emissions deleted, ac/heat deleted, making my own lights and fans harness, stock computer, and bolt ons
