Ok so today, I get my lightning headlights/corners, and go to install them. I get them installed all nice and neat. Then I notice this new wiring harness in the bottom of one of the boxes. I then look at the lights and realize that I completely didn't hook up the 2nd "eye" looking bulb. The one problem is that with the new harness, I have no clue where to to plug in the main plug. (See Link, its the 9007 plug.)

Do I plug the 9007 plug into one of the old existing headlamp plugs, or is there some special spot somewhere else?

I drive a 2003 F-150 XLT, if it makes a difference.

 

are they projectors or something?

 

on the original headlights you had one bulb for hi and lo. this wiring harness looks like it converts the system to one bulb for hi one for lo. i think that the harness comes out of one of the 9007 headlight sockets and splits into 2 pigtails. it has 2 plugs on each pig tail for each headlight housing. one for a 9007 (your low beam) one for a 9005 (your high beam). you can get away with how you have it set up now but tomorrow your going to need two 9005 bulbs to go in the "eye" socket then you can plug the rest of the wiring harness in. it looks complicated but its pretty simple just take your time.

 

Bingo. My headlights were the same way, mine has a projector on the lights with it as well, and used the same exact kind of harness you have there. The 9007 hookup thats on the bottom end of that diagram plugs into one of your factory 9007 sockets, then you just plug everything else up where it needs to go.

 

Bump the old thread! Sorry guys but I just got the same exact lights with the same exact wiring harness and my high beams (lows plus the projector all come on from off to on), If I hit high beams, all lights go out, but if I hit flash to pass, the projectors go off and the lows remain lit like they should from the get go.

Did I just pay 170 for a junk harness included? BTW these are depo lights.

 

Double check all your fuses(including truck fuses and relays) and all of you're connections. Then make sure the right blubs are in the right place.

 

Hey nolongerjeepin, I did nothing blown. I am suspecting it is the relays in the wiring harness that was included, they are either cheapies or just the wrong relay for the wrong application. I took one of them apart, they have 4 connections, 1 coil and one switch, its on or off...which doesn;t seem right to me.

Hasn't anyone else had this problem with this wiring harness? To get to low beams from switch off, you have to hold your flash to pass and turn the switch to headlights on to get low beams, if you do not you get highbeams automatically, plus to go from highs to lows, you just flash to pass, if you hit normal highbeams everything goes out.
