Review on H4 Headlight Relay Harness Kit for Toyota Pickup & Tacoma - Solve Dual Ground Problem by Bill Schlag

Purchased and Putco H4 harness. It's much better, with a few minor differences. Advantages: - battery cables protected by a fuse (Putco has no fuse) - headlamp connectors are ceramic (Putco connectors are plastic) - easily accessible standard relays are used (Putco relays are hard to find locally) - it will take 80- A relay used (probably too much) (Putco relays are rated for 30A) - the wire harness is encased in a heavy duty black wire harness with detachable wires (Putco uses a reflective yellow plastic sleeve). and has a QD connection on the battery terminals. It's nice to have/convenient, but in my opinion it's not worth sacrificing other benefits. My setup was on a 2000 Jeep Cherokee XJ. The installation went quickly and without problems. Remember to use waterproof tape on connections and ground to bare metal.
