My neons are now controlled by the ride control buttons.
I found a 3 button pod in a junkyard yesterday--the fourth junkyard i've searched.
The backlighting in the buttons is controlled by the harness that was hiding in the console, so they dim with the dash. Also, one of the LEDs lights up to tell me when the neons are on. I'm using a 30 amp relay which is overkll by about 29.5 amps, so i'm not worried about burning up anything. After all my research on bistable flipflops, it turns out that the ride control buttons are toggle on/off...
