Resistor wire to coil

Hi, I'm tracing wires to the coil on my 1974 3500 Auto before I fit electronic ignition.
I have the two white/black wires to the distributor and tach on one side of the coil and two white/yellow wires (one thicker than the other) on the other side which I assume are the feed from the starter solenoid and the resistor wire.
6" from the coil, the thinner wire is connected to a pink/white wire which I am assuming is the resistor wire. Before I start unravelling the loom and cutting wires to replace the resistor wire with a new length of standard wire, is my assumption correct?
The workshop manual wiring diagram (ref 2RA309A on bottom left of the diagram) shows a resistor with a white wire in from fuse position 19 and a white/yellow wire to the coil.

Why would you cut anything and not just run another wire? Best use heatshrink on the end to isolate and leave be so in principle it can be reversed.

Dont assume anything! Check voltage at the coil input (with ign on of course). Mine is also a 74, and I have 12v at the coil, and have the correct coil for 12V input, IIRC a Lucas DLB101, 3 ohm.
