Classic/Antique Car Repair: ELETRICAL WIRING HARNESS, hemmings motor news, 1969 mach 1

Question
I OWN A 1969 MACH 1, AND SINCE THE CAR IS SO LOD I WAS THINKING ABOUT REWIRING THE WHOLE CAR FROM THE HEADLIGHT TO THE TAILIGHTS. I'VE LOOKED ON E-BAY AND FOUND A COUPLE OF WIRING HARNESS THAT WOULD WORK BUT THEY COME IN DIFFRENT CIRCUITS AS IN 12,18 OR 21 CIRCUIT, WHICH ONE SHOULD I GO FOR OR WHICH ONE DOES MY CAR TAKE?

Answer
Get a copy of Hemmings Motor News the old car hobby bible for classified ads for old car parts. There will be several makers of the correct wiring harnesses for your car, custom fit. The ones on E Bay are universal jobs that have built in headaches.
