    4 out of 54 out of 54 out of 54 out of 54 out of 5 Great kit to replace factory wiring
    Review by Steve from , on 7/10/2019
    This is a great replacement for the always degraded factory Mopar wiring. Kit includes virtually every wire in the car, new firewall bulkhead connectors and accommodates a number of common upgrades (electric fuel pump, fog lamps, electric fan, VSS style speedo...). Not for the faint of heart (lots of trimming and soldering to do...), but this is the best way to solve those annoying electrical problems old Mopars are so well-known for. My only nits: no connector/plug kit for auto transmission neutral safety & backup lamp switch, engine bay harnesses left out wires for heater fan and a/c compressor (both nits are relatively easy to resolve but AAW should address).
