ARB Wiring Loom Trouble

**mortalenema** · 12-17-2006, 11:55 AM

Here's the story:

I ordered IPF lenses and Fatboys for my '99. The order was put on hold pending a new lense shipment. In the meantime I thought I would get started on the wiring. I just finished installing the new wire harness, but I have a problem. When I click on the high beams they will not go back to low unless I turn off the lights completely.

Could it be the stock bulbs or bad relays?

I guess I'll just go change my fluids for now...

Sounds like a bad relay.....

Does anyone know where I can get replacement relays? They seem to be some sort of secret australian relay not to be shared with the rest of the known world.

part number is AR274 at NAPA, and R683 at Pep-boys (i think).

I have two spares if you want to buy them.

Both unused. I bought 2 locally at different places, then found 2 online for the same price as 1 locally, and as i was buying other harness parts from the same online store, i got another 2 Bosch relays. And apparently you can't return relays to most stores, so i have 2 extras now.

It took me all last night to research the relays. Thanks CDX74 for the tip. I went to two NAPAs and a Carquest today and have now replaced all three relays.

I still have the same problem! This is driving me nuts!

I plan to disassemble the whole mess tomorrow and start over.

I'm still open to any suggestions...

what does this have to do with an ARB?

^funny

Figured it out!!!

It was the fog light relay!

I was going through some tests this morning and I heard the fog light relay clicking along with the headlights. I took it out and the headlights now switch properly.

Now...

How do I wire up the fog lamps without that relay?

I think I'm just gonna take a break, wait for my lenses to arrive, and worry about the fog lamps another time. Guess I'll be making another thread when I cross that bridge.

Get a new relay....

headlight wiring harness by ARB. Part number is M002. I have one in my XJ.

Shown here with a set of IPF headlights.

replace the fog relay and see if that works man and if it deosnt the arb makes a fog/driving harness that connects to the other and not to mention it makes the fogs brighter had the same prob

Do you have stock foglights ? If so you are getting a backfeed from them . You can pull the foglamp relay OR what I did was to ground the extra wire coming out of the stock drivers side high beam socket that goes to the fog lamp cut-off relay . Everything works except my fogs stay on with highs , but that's a plus for me .

Check the post dates. He fixed it three years ago.
