Cig lighter and DLC off with key mod

[Tonimus]

I've got a OBDXPro dongle that I got for programming, but I also like to use it for extra gauges on my phone. As such, I like to leave it plugged in. I also have a phone charger plugged into the cigarette lighter. Thankfully it only took me a minute to realize that these were full-time hot, not ignition hot. Whipped up a little easily removable mod to make it so the DLC and the cigar/cigarette lighter are key on only.

It uses a mini fuse circuit tap, a mini fuse extended fuse holder, and a mini relay. Grounded it to the body bolt right nearby just so I didn't have to find a ground in the box.

Works fantastic, and I can leave everything plugged in.

Nice, I like that the wiring isn't hacked and you can restore to normal anytime you want.

Very nice work indeed. Built a better mousetrap.

This same mod could simply be placed in the aux power outlet fuse if you have no need to de-power your DLC and want to power down the other outlets.

I replaced the cigarette lighter with a dual USB-A and wired it to one of those fuse taps into the fuse box on the left side of the dash. I made sure that the fuse I used was ign hot.

I may tap the other front socket into the same circuit as the cigarette lighter and leave the rear cargo one on its own circuit.

I love it when I can actually see "the lightbulb above the head" flash on when there is a different avenue to approach something.

I tested my new 12v to USB power adapter. Draws 3.5 milliamps when not in use. No need to tie in the other outlets. My MagSafe charger and DLC are the only things I need to turn off with the key, so I’m set.

I wish these trucks had the same fuse box feature as the 2000-2005 Lesabre and probably 2000-2005 Bonneville, that have a 3 position fuse for the cig lighters , and each is fused separate, but moving the fuse over into 2 of the 3 slots makes its key on or always on
