I am re assembling my wifes 2003 Blazer S10 after replacing the heater core. The tach and fuel gauges are not working. I have 1 plug that I cannot find a place to connect. It is a 6 pin connector with 3 wires going to it and it is taped to the headlight switch plug harness. The wires are black/white stripe- orange and tan or white. Can anyone give me some advice? Thanks.

 

That is for the fog lights. If you do not have fog lights it gets plugged into the little holder under the headlight switch. Try rechecking the connection on the large plug on top of the instrument cluster. Also double check all the fuses.

 

Thanks Brother, that is what I have done already. Automotive wiring is not my strong suit.
