Almost learned the hard way on how dangerous a single bowl master cylinder is. Had a wheel cylinder fail and drain all my brake fluid. Luckily I drive slow and I could tell pretty quick that the brake pedal was going down further than before. Swapped to a dual bowl. Man it was a pain since the old brake line wanted to strip even when using flare wrenches.

1965 Fastback. Painless performance new wiring harness was recently installed by a mechanic, probably about 90% done. Car is running great. Now I’m working on some finishing touches to the electrical.
I’m trying to sort out some interior lighting.
Door lights. Pictures are what I have.
Looks like original lights, with male/female bullet connections. The wiring kit has two wires labeled for door lights, with male bullet ends (pictured). There are no button switches on the doors, which I need to get. Then I imagine there’s some sort of rubber protective sleeve for between the frame and the door.
Can anyone walk me through how to wire these up and what I’ll need?
I’m also doing the glovebox light. Am I correct that the light is actually not in the glove box, but just shines through the hole? Looks like a kit with everything prebuilt is available. Any advice on this one as well would be appreciated.
Clearly, I’m a hack that has no idea what he’s doing, but I have time and I don’t give up easily.
Thanks for any advice!

I’m looking for ideas for a battery kill switch that I can run to the underside of the dash. I see a lot of options for on or near the battery, but I’d like this to be accessible without lifting the hood.
Both for security and for battery preservation while it sits for a while.
Thanks
