Installing a 98 Trans Am LS1 into my camino. Looking for help on wiring. Have the trans am harness complete. Thought about buying a new harness from Street Performance but $800 has me reconsidering modifying harness. My way of thinking should only have to modify connections to go to interior of car. Looking for info on headers. Since I live in Cal has to have carb number on them (emission legal shorties) anyone tried to put f body headers into a g body?
