Hey guys i have 03 jeep liberty and a avh8400. When i connect the receiver to the trucks original harness the trucks gauges don't work and all the dash lights turn on. When i unplug the harness the gauges and lights go back to normal. Any ideas on how to fix?

Thank you

You have a serious install error. Have it done professionally.

For got to update.. I didn't notice i connected the Mute wires together. All is well.
