The stock V6, GM 3.4L DOHC engine cars came with the computer installed under the front hood.
Also the 3.4L DOHC hood fuse panel is under the front hood located in the right side--which most of the time is removed. We utilize the stock Fiero A/C and Fuel Pump relays.
Fieros with the 3400 Twin Cam engine installed have full instrumentation utilizing all stock Fiero gages and Main Fuse panel. By integrating the Fiero Main harness and donor 3.4L DOHC harness through our computerized automotive database, we generate CAD schematics specialized for each customer specifications.
