Well today I decided to do the 9004 to 9007 headlight conversion. I read through the entire 10 pages on this subject and I believe that I wired everything up correctly. Well when I turn on my lights they are on high. And when I switch them to high they light up dim? I tried switching the wires at the 9007 headlight socket but it still does the same thing. I am making my own harness. Maybe I should have just bought one but I thought I could do it and save a few bucks. Oh well what do you guys think im doing wrong? I switched the wires from the original driverside socket and connected it to my relays. Is this correct: the 9007 headlight socket is from left to right LOW, GROUND, HIGH? If I did that right then I guess my problem would be in the way I hooked up the relay? I just dont know Maybe I am just making this harder than it really is? Please help

 

Yea, make sure you got the three wires connected to the correct ones on the harness.

 

So you dont think my relays are wired up wrong? Afterall I am getting light. Its just the opposite of how I want it.

 

no, you swapped the wires incorrectly. i did the same thing.

 

The coloring of the wires are not necessarily the same colors for the harness.

 

Just swap the wires again... since the colors are not the same you have to play with them till you find the right combination. Also even you have it right on one side but wrong on the other you will see the "long beam" dashboard light, come on.

 

 

The HB indicator will not come on unless the headlight stalk is moved to its foward position and the 'pass' position (farthest towards you), regardless of what is wired to what.

 

for a 9007 wiring, it should look like this. Just swap the low beam and ground at the stock plug.

 

so if im reading that diagram correctly its saying that the at the factory plug it High, Ground, and Low. And at the new 9007 plugs its the same High, Ground, Low? I was thinking the stock wiring for 9004 was High, Low Ground? Please help

 

Ok so the stock harness is High, Low, Ground.

 

yes stock 9004 is high low ground.
