Can't Find DRL Circuit

[Gadget Man]

My coach sits on a 2005 Freightliner XC chassis. I would like to disconnect my DRL’s. I contacted FL support, and they told me the DRL’s are activated by a ground wire connected to the parking brake circuit. I was told to locate the Headlamp Module, go to pin #6, and cut the ground wire marked "125", which is a red wire with a white tracer.

Being a novice, I’m not sure what a "Headlamp Module" is, but I initially thought it was the black box under my dash that contains various fuses and relays. I was wrong. No such circuit or wire.

I called FL back, and they said Fleetwood usually mounts the module in front of the front driver’s side wheel, so I went into the front hood. I am still unable to locate a headlamp module or a wire described by FL. Plenty of red wires with white tracers, but none marked "125".

Anybody have any experience with this? I would die for a photo of this module and wire!

Craig: No idea where-- but this MAY be what it looks like......

Good luck.

your chassis shares the power platform for the bounders to, I went over and looked at moms.
the other place to look is under the driver side window compartment.
OR
below the dash behind the center pull out panel.
hope it helps

curious as to why wanting to disconnect the drls?

Thanks to the posts from Hooligan & powerboatr, I found the headlamp module.

I was able to locate the 125 wire and cut it. Freightliner did leave one step out however. Once the wire is cut, it needs to be grounded, otherwise the DRL's will engage as soon as the ignition is turned on.

For those of you wondering why I want to eliminate my DRL's, please read this thread.

Thanks everyone!

Craig - hate to wake an old thread like this, but I'm in the exact same boat you were in - HIDs that flicker due to low/choppy voltage.

Can you describe where you found the module? Is it inside the coach, under the hood, in the basement?

Thanks!

Mine was inside, near the base of the steering column.

I know this is technically off topic but it does have to do with DRLs

I went to church yesterday (We have no car save the motor home) so when I got back to the campground and backed into the site, Someone stopped and said " Your lights are on ".

I mean, the engine was still running, I'd not even dropped jacks yet. Of course the DRL's were on.

You really shouldn't have to cut any wires. Just pull out the DRL relay. On my Fleetwood it was located in the fuse block behind the drivers instrument cluster when flip up the cover on the dash. However that is what I had to put back in because when I bought it out of the U.S. it was already pulled out and we need DRL's up here......It's the law.

It all depends on your chassis. I got my instructions directly from Freightliner. Your chassis may be different.

Craig, thanks for the reply. I found mine inside the center console. Had to remove the bottom drawer. The module is bolted to the floor. Found the red/white wire labeled 125, and cut it. As you stated, that only caused the DRL to activate anytime the engine was on.

I then grounded the wire - but the wrong side. Important for anyone trying to duplicate... The pin 6 on the harness/module is what needs to be grounded - not the red wire coming from the parking brake. I crimped on an extra length of wire to the red piece still connected to the harness, and tied the other end to a grounding bolt on the firewall (just behind the gas pedal).

Works like a charm. Headlights are on ONLY when I turn them on. I owe you a beer.

We have a Spartan chassis under our Newmar and that's all I had to do except ours was under the "hood" and in front of the driver.

erkme73,

Glad you found it. Your's was a lot more difficult to find than mine.

You are right about grounding the module side of the 125 wire. I accidentally omitted that.

I drink Michelob Ultra...

Happy travels!
