If you plug 'em in and they don't come on, flip one of the plugs.

Wingo!


I had to flip them on my '08.

 

I bought my HID kit from DDM Tuning and had to switch the polarity. It is as simple as turning one plug 180 degrees, not hard in the slightest. When you plug your lights in to check and make sure they work, that is when you might have to flip the polarity. Plug them in and if they don't light up in a few seconds flip the polarity, its the connection between the ballast and the light itself.

 

No, it's the connection from the factory harness to the ballast. There is no way to swap polarity on the bulb to ballast connection.

 

Thats what I meant to say...Thanks

 

ya... I had to switch the writes with my XenTec's... I just didn't know why some people say that they can get away with not switching the polarity

 

No one with our trucks can say that...that i know of anyway. MAYBE if there using a relay or something like that. Fact is, these trucks switch the ground. Not the hot bro. Go outside with your meter, and check. You WILL have 12 volts to the bulb all the time when the truck is on. the switch actually gives the bulb a ground. With their relays...maybe they do it different. I myself, didnt wanna pay for something I didnt need. And yeah, I know about your other thread...some trucks have a REALLY touchy BCM..but for the most part, our trucks work just fine with a ddm tuning raptor set or any other set of HID's.

 

Ya... Some guys on cfans were saying that the polarity only mattered on older 355s... That's why I was asking... But I'm gonna be running relays w/ my new 55w ddm tuning raptors just to take away from any problems w/my bcm...

 

i have an o4 colorado with the 55w raptors with relay kit. no polarity reversing needed. (unless I somehow plugged in my harness backwards.) doubt it though.

 

dunno about that. Mines a 04...and the only trucks I have ever worked on were older. SO maybe...But why would GM change the way they wired the trucks? makes no sense unless there were an issue or problem that came from wiring it the way they did on mine..if so, i want a new truck you GM mutha fuckas! LOL

 

Idk... Coulda just been some guy talkin out his ass and didn't even install his own hids! Lol

 

Maybe...or maybe they did and I jsut dont know..lol. We shall see...more members will post up hopefully.

 

I don't know if I'm hurting or helping the cause but when I installed mine I didn't reverse em (they worked great) UNTIL 2 days later my passenger low went out so I checked the fuse and it was melted well needless to say I reversed them and still working great. I bought them off Ebay 35w....

 

Hmm... I did have a melted fuse to replace but i replaced it and no issues since. So jstu to make this more confusing, I'm gonna have to take a multimeter to my headlight circuit next time I take my grill off, (or if i melt another fuse any time soon)

The replacement fuse has been fine for at least 2 weeks now. :shrug:

 

06 crew cab colly with the ddm tuning 35w raptors. had to reverse polarity for the ground and they work great. every once and a while the pass side doesnt kick on - i just have to flip the lights off and then back on but thats no big deal, dont really understand it but im just to lazy to call up ddm and get them to replace the ballast because they still work, its just a PIA.

 

Well this info would tend to lead towards the fact that you don't have to reverse IF you use a relay kit from them..or your own. Which makes perfect sense when you think about it in electrical terms. But for those of us like me who just simply wire it in without the harness, we do have to....Sounds legit to me...

So for ease of use for later viewers...

harness from them, no need to reverse since your then just using the signal from the switch as a remote basically.

No harness wired direct...flip it so its reversed.

Simple as that.





Oh, and a blown fuse would NOT come from you reverseing or not reverseing the relay correctly. A fuse just like any other conductor, does not care at all which way current is flowing. Only a spike,surge, or short would result in a blown fuse.
And i dunno how ANY of you got anything at all to come outta your lights when wired backwards. Mine didnt even try to light up...lol. They just sat there. Dunno IF that could damge them or not...from what I have read though, teh ballast are pretty hardy...but hell, there's always the chance!

Yep you got it, that's exactly right. I know from experience as we have two 2007 colorados, one with the wiring kit and one without. Both 35 watt raptors but the bcm didn't like the hids on the silver truck so I needed the wiring kit

 

I'll remember this when mine come in
