There shouldn't be fuses on the ignition. Saving your wiring is a poor consolation if you conk out in the middle lane of the M6.
If it's original & you have a pre-engaged starter, the ballast ignition bypass is a good shout. Even if it wasn't used it was likely to be in the loom from the 80's on.
If it's added it could just've been taken as a handy spot to pick up an ignition fed live, possibly for a relay ( spot lights, air horn...)
So it seems I am missing the white pink ballast resistor cable from ignition switch to ignition coils, that is a direct wire instead. Also the white yellow from the ignition coil to starter solenoid is missing from my set up, however everything works so I'm not sure if I should just leave it as is...?
The cable with no connection at the end... Looking at the wiring diagram it seems where the white ignition cable is connected would have had a fuse leading to a bunch of green cables Originally I think this would of been Fuse 1-2 as per https://www.theminif...s-covered-data/. I think the 6 fuse set up fitted is just badly routed leading to more confusion but agree it could have been used to as a convenient power source for ancillaries not sold with the car.
Seems enough info points to a test fit with it directly connected without having any fuse connection between and then removing the rogue wire
