Up to me ears in rewiring my '77 to an '80's ignition....trying to wed the different harnesses.....studying charts till I'm crosseyed and brain weary on the terminology of the different parts.
The smaller the number the larger the wire.
OK, heavy short wire from the battery to the solenoid, 8 gauge?
The wire running from the battery/solenoid to the key switch appears to be 16-14 gauge?, a bit bigger in diameter than all the others.
Tomorrow I get this right or strip it down and start from scratch.....nah, too much time invested. Bugger!
