Year One Engine forward Harness

i would go with an evans kit. probably where year one gets it anyway. http://evanswiring.tripod.com/ if your buying a new engin harness anyway i would get the one set up for the dual fld alt and if its the electronic ign then so be it.. your gonna have to tap into ithe new harness for MSD with either anyway so get the one that has the dual fld alt wiring already in it...

actually, m&h electrical fabricators make the ones for year one.

since all you need is that blue wire, i would open it up, add the blue wire where applicable, and rewrapping it with the non adhesive wrap. i am running the msd trio and cut out the ballast resistor wires, used just the brown/dark blue white stripe for the start/run to go to the red trigger wire on the box.
