I want to add a tach dash to my truck that came with a non gauge dash. Can i do this without adding a new wiring harness?

thanks
David

Yes, the wire harness for the tach is a seprate piece.

David stop! The above is correct if adding the tach only. What I read was you were substituing gauges in place of the idiot lights too. If that is the case, go to GMCPauls web site. He has an tech tip on rewiring your idiot light harness. If you don't rewire or replace, you'll fried that cluster.

Thanks Jeff, that is just what i needed, i know how to hook up the tach, but needed to know how to swap over to a gauge dash.

Thanks

I just did a search to find out a little info on this topic and ran across this one. I've got a guage dash with no tach in my '72. If I'm wanting to add just a factory-style tach, could I get away with just adding the tach itself and the wiring harness for the tach? Would I need to change out the circuit board or anything else? Thank you.

You'll need a dfferent circuit board that will fit over the tach housing
