2nd Gen Non-Engine/Transmission Headlamp Wiring?

[PKleine]

I'm upgrading to sport headlamps and making my own harness. I have a relay for the low, high and fog lights. I'm using the OEM bulb connector on the passenger side to trigger relays for the headlamps. The low beams work, but when I select high beams - no high beams. I began trouble shooting and discovered the following:



Looking into the OEM head light connector on the passenger side: In low beam I have +12v at the left wire (looking into the socket) to ground. The center (low) will also act as ground. The right side is open.



In high beam I have about 1 or 2 volts at the left wire to ground. What happend to the common +12v?



Answer: blown fuse in PDC.



The way I'm triggering the relays is to use the common (+12v) (its actually on the right looking into the socket with the flat up) daisey chained to terminal 86 of the high and low relay. Then connecting the switched low to terminal 85 of the low relay and the switched high to terminal 85 of the high relay. Will this work?



Maybe not, the fuse blows for that headlight. The high beams don't work. The high beam indicator gets caught into a bright/dim condition depending on high/low selection, once its been set to high. So what am I missing here?



Thanks in advance.

Oh; the fog lights work fine. I removed the relay in the fuse box and inserted the jumper so I can fire fogs with hi or low.

Here is a site with lots of info and diagrams that might help: http://www.danielsternlighting.com/tech/relays/relays.html

Aslo check SUVLIGHTS.com

He sells pre wired harness'

I know Dodge switched the Wiring around a few times.

Hot triggered / Ground triggered.

Good luck.

I gave up and got harness' from SUVLights.com

The 12v is there all the time. The headlight switch just grounds the low circuit when lows are on, same for high beam. You need to run 12v to one side of your relays and trigger them with the ground circuit. bg

Here is how the switched ground headlamps are wired on your non-Sport Ram: https://www.turbodieselregister.com/user_gallery/sizeimage.php?&photoid=15712&width=4

The +12 volts is always at the lamp - always. Here is how I wired my Sport transplants: https://www.turbodieselregister.com/user_gallery/sizeimage.php?&photoid=14178&width=4

Thomas, I have a couple questions on how you wired your sport transplants.



1. Did you use one OEM connector to trigger both the high and low beams? Or did you use the right side for high & common and the left side for low & common?



2. On the diagram it looks like the common +12v goes to terminal 85 and the switched grounds to 86. Am I reading that correctly? Is it even critical as to which terminal the + & - trigger wires go to? That is, is polarity important to the relay terminals 86 & 85?



3. Does you high beam indicator glow dimly on low beam?

1. Did you use one OEM connector to trigger both the high and low beams? Yes - The high-quality schematic, mentioned later, should help you understand my harness-to-OEM wiring method.

2. ... is polarity important to the relay terminals 86 & 85? No

3. Does you high beam indicator glow dimly on low beam? No

Send me an email address via PM and I'll reply with a high-quality JPEG of the schematic.

I run a relay on the low beam side and another for the high beam side. My harness plugs in like you mentioned and uses the ground to trigger the relays.



On low beam I have just the factory lows burning. Results in fewer folks flashing thier highs at me. On high beam, I have all the high beam filaments burning. The lows get shut off.



There is a ton of ways of doing it. But after fighting mine, I had to talk myself into the whole negative switched thing. My lights get 12+ switched from the relays.

Thomas, I sent you a PM.



I'm trying to set my harness up to work like the OEM sport setup. For low beam the outboard 9007's low filament on. For high beam the inboard 9004's and the 9007's high filament on.



Thanks for the replies from everyone.

Where is is a good place to buy the sport headlights for a conversion these days?
