The white and yellow comes from the live to the coil, and then there is only one wire, it runs from the other side of the coil to the dizzy (and inside the dizzy to the contact breaker).
Doesn't matter what colour it is!
On mine it is brown, too, but after 50-odd years I expect it has been replaced a few times.
Good luck, hope it works.

Yea mines not quite 50 years yet 38 so close enough,.. Brown was from lumenition to ignition join which then went white n black to pos on coil but also has piggyback to cockpit ignition
No, that would be the positive feed to the lumenition. If it’s only 38, it’s presumably a 6a? In which case, have you got a ballast resistor on the wing by the wiper motor? You need an ignition fed supply (from the ignition switch, originally white) to the ballast resistor, then from the other end of the ballast resistor to the coil +
There should also be a wire going from the starter solenoid to the coil + (this bypasses the ballast resistor when cranking).
Yea it's an80 gte so last response makes sense, and yea got new ballast resistor at same time incase was fried..., right il give that a bash tomorrow, thanks so much
So after auto sparky here, put in new lumenition wired as he thought ect, tried Cranking her over after few tries at starting the ballast resistor and it's metal holder were stinking hot, why? And does this mean he's made an arse of it?.
