maybe its broken, thats why it was so cheap.

 

well my window switch wasn't cheap and it doesn't work either, so i'm bettin the price isn't the problem here

 

try just strippin off the wire and twist the bare wires..those stupid clips dont work all the time..i had my temp gauge peg out once because that stupid fold over clip didnt work and my electric fans didnt come on

 

i actually stuck the bare wire in the pin with the white wire and still no worky...

 

sucks to be you..lol ill look at it when you come down

 

Please help me get my tach working
There are four wires on this...One for the lighting, which is working; a ground, which is grounded; a power wire, which has power; and a tach wire which is demonstrated in the video below. The red light is pulsing like I guess it should be. There is a setting on the back of the tach for how many cylinders from 2-8..I've tried them all and still no worky. Same results as the last tach I tried...Any suggestions?
