Found a black and white cable coming from the front driver side brake caliper, does anyone know what it goes to?

 

It is probably the wire to a wheel speed sensor - used by the ABS (Antilock braking system). I would trace the wires from the ABS module and see if you can find where there is a break in the wire going down to that wheel.

 

it’s me account password won’t reset, I was hoping it had something to do with it not wanting to start in park sometimes. Or would that be a neutral safety switch

 

I've had a few times my 1996 C1500 didn't want to start in park, and I had to move the shift lever to drive and back to park, in order to get some type of switch in the shift mechanism on the column to close and let me turn the key.
