Anybody know which wire that plugs into the back of the cluster is the signal wire for the temp gauge? I just bought a digital temp gauge iwant ot try out and all it needs is a +12v a ground and a signal wire. I hoping to use the stock sender just need to know which wire is the signal wire.

Thanks

Also need to make sure you new gauge is in the same spec as the stock sender
