coming out of the harness there are 4 wires, one (red) that is the power for the high beam. one blue wire that is the power going to the low beam, and two black wires coming from the center post, one going to the low beam, ground, one going to the high beam, also ground. now, what you do is the following....

Starting with the red high beam power wire. coming FROM the light, cut the wire and splice it into the blue low beam power wire, making it so that one wire runs power to both lights. now, take the ground from the hi beam and connect it the power wire for the hi beam. and that should fix it.

what you did here is change the ground from the middle terminal to old low beam power cable, changed the low beam power to the center terminal. here is a diagram, like i said, the lights are wired for a 9007 bulb, and your truck has a 9004 bulb.

let me know if you have any questions

ok. in my 5.2 Ram 1500 I was checking for current drain on the battery. I have a high drain. I pulled every fuse and found out it is the "50 amp Park Lamp/Horn". I've checked everything from under the dash to along the entire wire harness and all the lights work fine if it's plugged in but there's still a short to ground somewhere. also a few other issues like no power to the code reader port and no fuel gauge.
anyone?

I believe there’s a spider brand headlights and my truck is a 2000 Dodge ram 1500 Quad cab four-door sport with a 5.9 engine any help whatsoever would be awesome,my truck I wired the red hot wire from the bulb side of the headlamp to the blue wires coming from the low beam bulb side of the headlamp to create a single power wire source between the low beam and the highbeam and I took the ground wire from the high beam side and connected it to the red and blue wire the lights turn on the blue highbeam indicator on the dash is always on lights won’t go to high beams. There was never any problem with original lights

Do you have a test light? I'd pull the lights out use a test light on the connectors coming from the truck to make sure which feed is lows and highs. Can you verify for sure that the colors one the headlights are right. The wiring should be straight forward but the colors most likely will be different from headlight to headlight. Once you get your low's straight then the highs should work. If you still have the same problem put the stock one's back in and verify that everything functions properly still then start testing wires again.

There should be 3 wires

Low's
Highs
Ground

Halo
