getting close to fitting my let engine in the nova, identified most the wires but not sure about the big round plug which links to the dash loom from the calibra I think? Got the black switched live, fuel pump and that. Is the rev counter cable in a different place between the let and xe? On my xe its near the coil but on the let its by the ecu? Is there any wires I can do away with from the engine loom as Ive not had a proper look yet. Anything else I should know let me know.
