i just bought a heavy duty H4 wire harness from suvlights.com. I read the review from the toyota tech page and it seemed very easy to install. I grounded the wires, attached the new wire harness female plugs to the male part of the bulbs, and then attached the wire harness to the battery. I followed the wire up exactly. I even attached to fuses to the end of the wire harness. I put in 20a.

After everything was installed, I never got anything to happen. I didn't blow a fuse and i didn't get any light. I replaced the wire harness female plugs with the factory female plugs and the bulbs lite right up. Not sure what happened.

Is there anything that i can look for to see if the harness if working? I grounded the wires to the sides of the engine walls where there are pre-threaded holes. I have used the same holes for aux lights and the grounds worked fine.


Any help or suggestions would be great

 

So you get no lights and Phil gets hitgh beams only? Nice QC at suvlights.com

I think we need another vendor for these items...

 

suvlights are a good company. Did you try calling them?? It would make better sence than posting here. I would call rather than email. They have always been very helpful over the phone. Talk with Jen

 

i did contact them, but i also wanted to know if anyone else has had a problem

 

I had a simliar porpblem when I first installed my HIDs from them. I called and they told me to reverse the connection. That worked for me but that was a different system but it was a simple fix....whew
