Default wiring harness question

Is the engine harness on my 84 corvette separate from the chassis harness. I am trying to strip out the engine harness because i dont need it anymore car is converted to carb and running a fuel cell with its own wiring and i bought all autometer gauges. All i need the car to do is have tail lights, turn signals, head lights and turn signals nothing else.

Yes - the forward lamp harness is 1/2 of the C100 connector under the hood on the firewall under and just left of booster. I don't recall if the forward lamp acts as the retainer or if the engine harness acts as the retainer but once you remove the gunk and the through bolt it's simply an unplug. If you needed the connector aspect of it to act as the retainer then you could just unpin the engine wiring half and use it with the through bolt to hold the C100 body and the forward lamp harness together. I do believe you'll need both halves and the through bolt to keep it together. You could repin the C100 inside the car and the engine harness under the hood to clean up your wiring install but it might be considered an 'effort'.

The ECM pass-through on an '84 I thought was pretty straight forward for removal. Maybe 4 connectors to unplug in the car and done.

This is I believe a typical forward lamp harness connector to the C100. The missing section is the engine harness. If the '84 is like this you could just dispose of the entire engine harness section.
