Trans Temp Gauge Install
I'm wiring up a trans temp gauge with a light, all the instructions are very clear but my only question is:
Is a good 12v switched hot the wire from the TCS switch in the center console? If not, where is the best one?
Should I wire the backlight of the gauge to a 12v that only comes on when the headlights are on? If so, where do I find a wire that's only on when the headlights are on? I'm thinking one behind the HVAC controls? Any ideas?
Thanks in advance.
Should I somehow coat the wire or insulate it so that the air doesn't reach it? Or does it not matter?
