Got the dash panel LED upgrade done and, while I was at it, installed the poosh-button lightswitch.
Took a little time to ensure I had as good a ground as I could get using a 1/4-20 bolt through the dash - I'd already installed the Kascar grounding kit, testing my ground out with a test light to the hot side of the battery and then hooked up the switch.
I'd taken the box up to a local hardware store and couldn't for the life of me figure out the threat pitch. Tried all kinds of 10-24, 10-32, M6 and others, even the stock bolts wouldn't fit, so what the heck, I took a 10-24 tap to it and used some black oxide panhead screws to hold it in place. Now I need to replace all the panhead screws on the dash.
It'll take a bit of getting used to but I like it.
I'm young enough I appreciate technology but old enough that I'm getting to resent it.
