This must be a beat to death question but here goes.
On a 68 CS it has original wiring, what I need to know
is where this resistor is located or is it a special wire with
resistance thru its whole length?
For now I would like to shunt it vs pulling in a new wire
do to winter weather conditions at this time.

It's a special resistance wire with resistance it's whole length.

 

Thanks Franklin and Numbers.
I switched over from a Allison to Crane XR 3000 I ran a 12 valt hot switched under the dash, now I want to clean things up and run thru the ignition switch. A short three year test going on here.

 

I was right behind you when you first posed the question, but the site went down, so that's why I was late with the info.
