Ok just want to start by saying electrical is not my strong point!! I tried to be smart but failed miserably!!

So installed & wired up EGT & Boost gauges to dimmer switch directly (1st fail!!) Gauges light up but don't dim or measure anything when the dimmer is rotated the needles spin back & forth before stopping where ever!!

So I wired red to pink
black to black
yellow to blue

I am guessing yellow to blue maybe correct (for the dimming?) but from the other posts I have read wire the + to something else like cig & wire the black direct to battery?

Any help greatly appreciated!! Spent 3 days doing everything & very over it now!!

It all started with the crappy fit pillar mount! But soo close & yet so far!!
