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

Revainrating 1 out of 5

Warning: poor workmanship and potential fire hazard!

You can read the ads that repeatedly claim that this harness will fix weak headlight problems, so I needn't repeat myself. but I would like to know how this is achieved if the wire used is actually LESS than the standard wire?!? What does that even improve if there is actually only ONE headlight connected to the relay? See photos now. 1) Wires seem adequately crimped, although the connector is actually too small for this application. 2) Oh look! NO WIRE WILL BE CUT FROM THE END. It was the same on ALL crimps with more than one wire, god that's helpful! 3) This is where the fire hazard comes in: hold the two wires, the left one, the one in Fig #2, and presumably 12 ga, the right one is REAL ACTUAL 12 ga stranded wire. Note that the outside diameters are almost the same (they are actually larger), but the wire itself? You can see for yourself. Definitely NOT 12 GA. You laugh? It's not even 18 GA! This is how car fires occur due to bad wiring. Finally Photo 4) Oh look, one more! I will also mention here that each of these wires were only disconnected after a light inspection, with the white one remaining crimped at least until removed from the socket and the other two breaking before they could be installed. I just re-crimp all the connectors and install them anyway until I see the actual size of the wire. Now. No way. It's bad enough to be ripped off, but THAT? .This is absolutely dangerous and needs a solution. Was the one I have an accident? Anything is possible, but I would never risk it. So. How do I put a minus star?

Pros
  • Pretty impressive
Cons
  • So-so
