My harness grounded out the hot gen wire to a body clip, burned it. I am replacing with the correct factory harness. Finding a couple items not right from the past. The 2 wires (orange/white) pictured where hanging out down by the master cylinder. I ohm'd them out, the are going to the brake switch. I must be going mad, thanks for any help.

Did it originally have manual brakes? The brake light switch for manual brake cars was under the removeable floor board. Maybe its been upgraded to power brakes?

Wouldn't the wiring harness NOT have the gear selection plug in the harness tho? When I went to go buy the new harness, it specifies auto or manual. Yeah, no idea if it was upgraded. I doubt it as it was already a highly optioned car.
The question would be if either manual or auto trans both have the provision for either brake options. That would seem more likely....making more sense now if I can confirm this.

Manual brakes, non vacuum assisted, not manual vs automatic transmission. My parts 88 has manual brakes, are they barrel connectors? The brake switch is screwed directly to the underside of the removeable floor, on power brake cars its inside the car at the top of the brake pedal hinge area, i guess its possible that both styles exist on the same harness?

Yep, just confirmed this with Fusick. The only 2 harness are A/C and non-A/C cars, so yes the factory harnesses had provisions for both, that explains it now. Yes they are barrel connectors. So your manual brake 88 has a spare set of orange/white barrel connectors for the power brake sitting unused up under the dash them.
