I have no clue what I need to do then. Obviously I need a relay from what your saying, which I don't know how to wire in. Cant find a diagram for it. Also what relay to buy who knows.

 

I keep seeing a lot of guys saying the resistor fixed both the flickering and the lamp out, and they aren't using a relay..


I have this diagram, which makes sense for the use of a Relay:



Power is drawn direcltly from battery, using the factory wiring harness to switch it on and off. This would still require a resistor I believe though to fix the lampout most likley. So.... the question is what type of relay does one need.

 

I know I am posting a lot on this. I have also been reading some guys have used 25V 10000uF capacitors in place of the resistors...

Again whats the purpose of the relay?

 

The purpose of the relay is to carry the high startup voltage the ballast pull. Some people will use their ballast without a relay but the point of a relay it to be able to protect your trucks OEM headlight wiring which is small (18ga I think). Potentially, if you pull too much amps through a too small of a wire it could heat up and burn in two or melt the insulation off and touch something else causing a short or a fire. Thats why a SPDT relay like shown below is used. These are standard automotive 12v relays. You can use a 4 pin relay or the 5 pin.

Typically you would use only the trucks HL wiring to POWER to the relay because it only needs something like 200mA to power it. The relay coils contacts are 85 and 86. So 85 would be ground and 86 you would either cut and plice the headlight wire to it or t-tap a headlight wire to 86. In the picture it shows pins 30 and 87a as touching and being closed so you dont want that. You would take a wire and go from the battery to pin 30 and take both (+) ballast wires and go to 87. So what would happen here is when you turn on your HLs, power from the trucks wiring powers the coil in the relay via pin 86 and that energizes the relay and closes the contacts which allow (+) to pass from 30, thought the relay and out through pin 87 and to the ballasts. Make better sense now?

But do yourself a favor and take some good pics of your ballast and connectors and wiring that came with it and post so we can make sure you are told and given everythign you need. Also, what type bulbs did you get? Are the HID hi/lo or HID low and halogen high?

 

Yeah that makes sense, I knew how a relay works persay, it was more so which relay to buy. I wasnt sure if there is a specific one, but I think I could probably find a standard 12V Auto relay anyway so thats good. Thanks for the tip.

Questions:

1.) So do would you run the Ground Wires for each bulb then to the body of the truck if using the relay? Like in that digram I posted?

2.) Would you use a heavy gauge wire from the battery to relay then or the same size that comes with the kits?

3.) I would still need to use the resistors to get rid of the Lamp Out correct?


My kit was a $60 ebay kit a buddy ordered. It is a single 9007 bulb that only operates the Low Beams. Since my truck is an 05, they used single bulb dual filament Halogens. This HID kit is only a low beam HID, I wont have any use of any type of hi beam. Which is fine because these things are bright as snot it seems like.

 

I see you ordered another kit BTW. Thats cool. But to answer your Qs, the diagram above it a bit deceiving. The wire isnt going from the bulbs to ground. The bulbs plug into the ballast and there are two wires off each ballast. One is (+) and the other is (-). Thats what you see going to ground.

As for what size wire to use, I would say either 12-14ga wire.

Resistors will still be needed to trick the PCM.

 

After reading all the wiring problems with the HID's, I may stay away from them.

 

Its not hard if you understand WHY they flicker or strobe. My kits were exspensive but never once flickered. You get what you pay for.

 

Yup, still waiting on my relay from HIDextra that I 'forgot to tell them I needed". Hope its smooth sailing after that, or Im gonna be one unhappy customer (literally and figuretively)

 

Interesting, I've been meaning to get in contact with HIDextra's techs to get them to help me solve my problem(s).

1: Work great but completely RANDOMLY flicker once every so often, could be every 2-5min or 1-2 times per hour or not once the entire drive . . . random. But I did notice the majority of the times, it could just be a coincidence, is that it flickers once after applying the breaks softly (rolling to a red about to turn green light) then releasing them . . . as I said it could just be a coincidence

2: Everything set up as instructed; Lows work, Hi's do not. I tried pulling the jump cables = no change. Put them back in and switched both sides Diodes and the Hi's became lows and lows my Hi's . . . would rather not have to run my lows having switched them inside the truck to Hi position .

Entire set up is HIDextra's Bi-Xenon 6k h13/9008 bulb kit.
