Need help finding new temperature gauge

You CAN use a test lamp, you just need a battery. I quite often "jerry rig" stuff.

You have some RadShack clip leads? Just take a length of wire long enough to reach the sender, Hook one end of your light to that wire, then hook the other end of the light, and a probe going to the kick panel connector to a battery.

Just use your head..........."How can I hook this up?"
