Default Re: wiring question

Yeah sorry I didn't give much info. The new harness has gauge supply (+) and gauge sender wires. When I said old gauges,I took an old set of vdo gauges and temporarily hooked them up accordingly to harness instructions. They worked. When it comes to wiring the exsisting (factory) gauges the wire colors don't jive. After some trail and error I've got the gas gauge working as well as the temp. The factory tach has a green wire and a brown wire. All I have is a purple wire from my hei distributor. The other gauge I'm not sure about is the battery gauge. I've got a red and black wire. When I hook up the red to hot and the black to ground I blow the gauge fuse. When I hook up the vdo volt gauge temporarily it shows 12 volts. I could just use the volt gauge but don't want to. I hope maybe this clears things up.
