We now offer a new reproduction conversion wiring harness to work with the original style reproduction 1969 Chevelle Malibu & El Camino instrument cluster warning gauges with tach.  This harness kit works to modify your original warning light dash harness, front end light harness and engine harnesses when upgrading to gauge & tachometer setup. 

If you currently have warning lights and are upgrading to gauges, your existing wiring harness is different and will need this harness.  We sell in a separate auction a complete set of oil & coolant sending units & tachometer & gauge dash cluster (we also sell all components individually).
