Well I decided I wanted to put the Holley ecu inside the car to make room for a battery in the engine bay. Really don't want to deal with all the NHRA rules for having a battery in the trunk. Plus the ecu isn't rated to get wet. Ended up having to drill a new hole in the firewall for all the harnesses to run through. I decided to mount the ecu in the glove box and have the main relay and fuses mounted behind the glove box.
Still cleaning up the wiring so forgive my mess.
Also I still need to mock up a new intercooler pipe to clear the battery. Going to be a tight fit! I probably have to notch the core support for the extra clearance I need.
