Foglights On With High Beams


Recommended Posts

I did the 26/26 jumper with a piece of thermostat wire. Working fine so far.

 

Does this allow you to turn on your reverse lights when you turn on your cargo lights? The point of using the diode for 26/26 jump is to have the cargo lights on in addition to your reverse lights, when you're in reverse. If you are able to control your reverse lights with the cargo light switch, I would like to find a way to override the cargo light non-op while in gear feature, to blind the morons behind me with their brights on.

I've thought about a light bar for tailgaters.... The brights aren't an issue as both my back window and topper back windows are tinted.

This has only allowed my cargo lights and reverse lights to come on together. I tested it today and as soon as you shift to drive it shuts off both. However they will come back on when I shift to neutral.

You can disregard my request for the diodes. The radio shack in my area went out of business but there was one close to where I worked. They had two left so I bought those. Radio Shack must know about this mod and increased the price to $1.50. Ha! Still one of the cheapest mod's I've done. I've traded my 2013 Ford Platinum for this truck and there are two things I was missing. The fog light switch was built in to the headlight switch on the Ford and could be pulled and left in that position to leave the fogs on. That quirk has been resolved with the jumper, now to add ambient lighting. I appreciate the research and advice. I could not pull the harness out, too scared or too stupid, so I installed the jumper with it plugged in. It was difficult to get to but I did file down the ends as directed and inserted the ends in the corners as directed. They seem to be in there good enough but my OCD will require me to use a small zip tie to help hold it in place. My OCD also noticed that the fog light indicator light on the instrument panel does not light up either. So now I find myself looking for a reflection in the car in front of me to make sure they are on. Thanks again to those who post for those of us less challenged.

I've noticed that all 6 RSs around here seem to be closed anymore. The only one that I know of for sure that is still open is one back home, 200 miles from here. Just did a search on RS's website, 50 miles to their nearest store.

 

Still, $1.50 is still a great deal for this mod.

Is the output for the #18 pin for the hi beams a normally closed circuit? I was working on my light bar and put the voltmeter on this pin and read +12v with the low beams, and 0v with the high beam lever activated.

Apparently I need help with this I have fired light bars back up lights fog lights everything but I can't get this one I added diodes to work with cargo light and back ups but I can't get the fogs with high beam to work I've easily tried 20 times 1 or 2 diodes each direction tried everything and can't get it need some help I've got hid headlights and have 2 led cubes for fog lights with the factory switch not sure if it going to make a difference I have a 2015 silver rally edition not sure if the wiring was changed from 14 or not

Ok, so I spent the last hour reading through this thread and this specific question wasn't asked. So the BCM handles the task of turning the fogs off with the brights and there hasn't been anyone who has successfully attempted to bypass this either...but with that said, is it possible, with the combination of jumpers, switches or relays to use the unresponsive fog light switch to toggle on/off a light bar? it would seem that You would need to intercept the fog light switch before the BCM and have that go to a relay that goes to another relay that is tapped into the high beams signal. This would allow power to the relay controlled by the fog light switch only if the highs at on. Or would I be able to tie into the high beams power source going to the fog light controlled relay allowing the use of only one relay rather than two. Any ideas?

Have you seen this harness from Gen5DIY?
