I have an oil temp gauge in my center console. It appears the PO unwired the temp gauge above the fuel gauge and wired the send to the one in the center console. Can I run the two gauges simultaneously? It's not mandatory it's just I don't like having a gauge not working. If I can how should it be wired?

Gauges work by measuring the resistance to ground through the sender. If you hook two gauges to the same sender each gauge will see a ground path through the sender and the other gauge causing incorrect readings. Using a couple of diodes between the gauge and where the sender wire splits should allow both gauges to read correctly. In theory anyway (IMG:style_emoticons/default/smile.gif) Diodes allow current flow in one direction only and would block each gauge from seeing two ground paths. Radio Shack has packages of diodes for a buck or two if someone whats to try it out.
