projector install question

I am installing a set of Morimoto H1 projectors in my 2007 Toyota Tacoma and the wiring harness only has one plug to connect to the right side headlight (driver side) 9003/H4. Where do I plug the passenger headlight 9003/H4 at? When I don't plug it into anything it doesn't work, but when i plug in the original halogen light into the truck my projectors work. What do i do with this passenger side wire?

 

He way mine is, the TRS harness connects to both ballasts through only one of the original halogen connectors.

I taped the passenger halogen connector off

 

But when i don't have it connected to the original headlight the projectors don't work. if i tape the connector off its like its not plugged in.

 

I don't think I understand what you're saying. Maybe someone else can chime in.

Do you have a TRS harness? Mine only uses the drivers side 9003/H4 plug and the harness has a run that gets routed to the passenger side to connect to the passenger headlight ballast and a ground. So with mine I connected the harness to the drivers side 9003/H4 and I taped off the passenger side 9003/H4.

 

yes i have yrs harness, but when you say taped off do you mean cut off the connector and tape all three of the wires together?

 

No. I plugged one end of the harness into a 9003/H4 plug on the driver's side headlight. The 9003/H4 plug on the passengers side was left unused so I used electrical tape to make sure water and dirt wasnt going to get in there.

 

See how there's only one "input from car". You only use the driver's side for the harness.

 

when i don't plug it into anything my projectors don't work.

 

Then I dunno. I'd recommend a call to TRS on Monday.

 

alright thanks for your help!

 

No problem. Sorry I couldn't be more help.

 

Hello OP, I had same issue today do not understand really either had wife help me. What it is, is that you do not have to run ballast wire to other side of vehicle. On opposite side of vehicle from relay and battery wires. you install a female plug on the wires that do not have a plugin on it. That plugs into your headlight wire from truck then the other end plugs into ballast to prong connector. So basically the long ballast wire does not go to anything unless you use canbus . That is not needed for our trucks. I hope that helps

 

OP did you get the issue resolved? I deal with TRS products on a daily basis and can help you with your issues if you can explain a little better to me whats going on. Your welcome to either reply here or msg me directly.

 

Why doesn't the ballist wire there goes a crossed to the other side not connecting anything, is it because its getting power from the other headlight that's all wired up with oem input

 

If the way your set up is what you drew thats wrong, the ballast wire (long one) runs from your driver side to your pass to the ballast. Although your method you drew will work for only low beam HID's, essentially though you are not protecting your pass side with a harness at all. As per that drawing all you are protecting with your harness is the driver side while leaving the pass side only protected by OEM wiring.

 

What do I need to do then the fix this

 

You need to run the long ballast wire to your pass side and connect that to your ballast, then passenger ballast to bulbs and it should work. If you have done that and ran into issues can you tell me what the issue was? also if you could tell me what harness your running that would help. Is it single xenon harness or bixenon harness?

 

If I plug ballast wire into ballast I am left with two male connections, single xenon, ordered two kits.came with 2 double relays sets, 4 ballast, 4 ignitors,4 bulbs,4 wires from igniter to bulb
