My barracudas gauges don't work. Speedo does at least. If I want to add some aftermarket gauges like OP, amp, water temp, etc. ,do I just piggyback off the factory wires?? The original harness was so hacked up i found a used one in very good shape that I am installing. I don't want to hack up my new harness installing the aftermarket gauges, just in case i ever have the money to have my gauges all restored by Redline or somebody.
