Can you hook up an oscilloscope to see if it is putting out a PWM frequency? Or maybe there is just a pull down resistor on it? I think you ruled that out when you Ohmed it out though.
I don’t have one of those. I do have access to a scope at work, but they won’t let me take it out of here, and I don’t think it would be useful for this.Do you have any way to check it other than continuity?
Like an ESR meter?
How hard is it to pull that switch from the bed? I have an ESR meter here as well as some other test gear I might be able to figure something out. But it's 14F here and supposed to snow and no garage big enough to stay warm.
Do we know what is on the wire side? Power/LIN/GND, etc. ?
I'm not sure of the combination, but more than once I've turned mine on using the bed switch, loaded something up, then miles down the road realize they're still on.
Now that I've tied in the extra strips under the rails and along the roof of my shell, I don't think I'd ever have it happen, but prior to, it was much easier.
I recall what I was experiencing was with the truck off, key out of the cabin, working in the bed, they kept timing out. A subsequent press of the bed switch turned them back on... for a while.
Isn't that what you want it to do? Same as cargo lights, you want them on long enough to do your work but not stay on all day by accident. If it times out click the button again.
Where is this plug located? ThanksCargo light wiring is the 2 pin white and tan wire with black ground.

I used this power source to power my lux magnetic rock lights (thanks @btsbarton ) these little lights just stick to metal and only draw 220mA so they’re not going to be popping any fuses.
They’re much smaller but much brighter than the factory bed leds

I mounted them up under the bed rail on the bedside where it is angled. This minimizes glare to the eye while providing maximum light into the bed.

Under the bed below the driver side taillightWhere is this plug located? Thanks
Looks great!Thanks, @Rockcrawlerdude! I spliced these in same exact spot as you did and they work great. Really easy install and super bright!
Yep, precisely what I did.For those of you that have a truck that came with bed lights are you just jumping the wires for the led strips from the existing lights?
Yep. 2x 220mA LEDs won’t hurt that circuit, IMHO.For those of you that have a truck that came with bed lights are you just jumping the wires for the led strips from the existing lights?
