Bubba yellow wire to starter
I have a yellow and purple wire taped together and ran from the fuse box to my starter. The yellow wire is fused and hooked up but the purple is just there. I assume it has something to do with the factory alarm being bypassed but was hoping someone else may know what has been done and how to make it not so ghetto!

On my '71, the yellow wire runs up to the positive side of the coil. The purple wire runs to the interior of the car where it gets it's power from the ignition switch. That purple wire also passes through the clutch safety switch (or neutral safety switch on autos).

I believe this is how the wires are from the fac..the reason is to delever 12v to the coil only when you turn the key and power goes down to the starter and back up to the coil,once running,the fused wire(the other wire that is hooked to the pos side of the coil) reduces the voltage so you dont burn up the points,this gives more spark to the motor right at first to help start the motor

Power runs from starter to ignition switch and other uses. Battery hook up point on the starter is a buss to supply the rest of the car.
One of these comes from the ignition back to the starter for cranking it. If this wire rots it burns up and needs to be replaced, possibly your fix. The fusable link doesn't always burn up since 20+ years corrodes the innards of the wire. Brownish or greenish looking wires.
Another supplies power to the coil from the iggy switch and is 'run'
The wire mentioned, resistance, is for the coil I believe to develop a voltage across it. The starter is a resistance on crank and on run there is an internal to the coil, I'm guessing, or external resistance- a resistor or resistance wire.
I read jac1502s post as only the yellow wire is being used, the purple was run for some unknown reason and isn't being used?
If the yellow &/or purple run from the main battery buss on the starter its only feeding power.
If on one of the little ones the yellow is probably to crank the engine.
Coil/run wires are small gauge and starter crank and cockpit supply are large wires.

The Purple wire should be the only wire that should be attached to the starter solenoid at the S terminal. It comes from the "Theft Deterrent Starter Interupt Relay".
The Red wires go to the ignition switch, the light switch, and the alternator output.
There should be NO yellow wire.
You need a wiring diagram, even if you don't get one from me, get one. It will make things alot easier.

It appears that the ywllow wire may have gone through the harness by the A/C box at one time and got burnt so bubba just by passed the harness and ran the wire right to the starter. not sure the original color yet i have to pull tape off

On my 75 that purple wire was/is for the "Clutch Start Switch" another regulated so-called safety feature that would prevent starting the car unless the clutch (manual tranny of course) is depressed in case the ninneys would try to start the car in gear and lurch down the driveway and run over the kids.....
