CB -
Did you read 2mbb's previous thread linked above? He recounts a conversation with someone at SOR who told him how to wire it. He hard-wired it, which is ok if you don't have the male end on the inclinometer wiring. If you do, the female socket is identical to the cigarette lighter's. Couldn't be too much from a junkyard. I'd guess they're the same on all contemporary Toyotas.
It would appear that the two green wires are from the illumination bulb are for + & - switched with the park/headlights. The positive also goes to the clock to dim the display when the lights are on (presumably dark out). The other leads are constant positive (like to the lighter) & ground.
If your dash is still apart, could you get the other measurements of the mounting tab (band?) - need to know how far up it is from the back, how far up from the bottom, & how far out from the side are the holes?
I need to make my own bracket. Guess I'll just epoxy it on.
