i was wondering how much i could get for a full engine body harness? The big one where, Part of it extends into the firewall to reach the headlight and signal lights etc. Some of it goes into the trunk to control the brake lights, reverse lights, antenna, TEMS computer, trunk light etc. and some of it is in the cabin, controls the climate controls, door lights, gauge lights etc. Just wondering if someone could give me a ruff guestement on this please
