Title: Pink resistor wire
Post by: 69 GT350 Vert on August 02, 2019, 04:31:29 PM
I've confirmed my resistor wire is functioning and my pertronix coil is only getting 5.6 volts.  Does anyone know if the pink resistor wire under the dash on a 69 shelby has a removable bullet connector?  I want to bypass resistor and get 12 volts to coil without splicing into OEM wires.   Any ideas? Thanks

I bypassed my Shelby and XR7.  The Pink wire is fed from the tach plug.  It is a two way plug.. one male.. one female.  Just unplug that connector, rotate the plug 180' so the pink feed wire is exposed.  Then run a wire from that connector right out to the coil.  Use a larger gauge wire to handle the load. Tape up the connection so that plug you rotated stays in place.   No cutting required.  I might have pics somewhere.. it is easy.. except removing the dash to get to the wiring.  Mark

Thanks! That sounds like an excellent idea.   Will try it.

It worked!  Full 12 volts to coil and pertronix.  Brilliant idea.  Not the way I wanted to spend 4 hours today, but it is done and fixed.  Thanks.
