Adding Circuits via unused options?

Ok - has anyone done this yet?

I know on the GCs and most newer model cars very few things change options to options... (Just remove a switch and a relay, but leave at least part of the wiring intact)


My thoughts...
Are there unused circuits that woudl make easy 'tap point' to wire things up?
Looking at the stock block there are several open relay spots.

Most notably, Rear fogs being the open on the top, and apparently Power pedals on teh bottom (but I have that option curiously enough?)

(sorry, cellphone, rough to read... - big right two are "Dodge only - fad fan high & low)


Has anyone looked into using those wiring points for accessories (really thinking, rear flood lights from rear fogs shoudl would be nice)

Or maybe I'm just dreaming, as I didn't even personally go so far as cracking teh boxes open to see if teh wiring was even there

So I guess that's a "No."

If you look into the junction/power distribution block fuse or relay locations and all the connector cavities have a connector then odds are it's a go. Inside the block is a series of contact plates spaced in layers for power and ground, some low line distribution blocks will not have a connector in every cavity for options. Certain popular options will have what the factory calls "Give Away" which means some parts of, or all of the electrical circuit for something like fog lights including a connector taped up to the harness for the light itself.

I would imagine you could not use the empty slots, because even the "give aways" have to be activated by the dealer.

Yes, just about everything is controlled by digital (Computer) module in the vehicle. Any existing circuit likely runs to one of the digital modules and is wired totally different than you would expect and you will risk shorting out and damaging an expensive digital module if you get to deeply into the wiring.

Adding a fuse to an empty spot in the PDC, likely will require pulling out or cutting existing wiring. Probably will NOT create a problem, but personally I wouldn't risk it, NOT to mention, the connectors are probably special shape to lock into the slots, standard off the shelf connectors might NOT work.

I'd wire additional circuits independtly and tap power off the battery or know source able to handle the extra power draw.

My additional Oil Press, Volt and Trans Temp Gauge, all its own wiring, the ignition switch power and lights were tapped off a splice into wires going to the intrument console of those sources.

My trailer wiring for the tow hitch (since I abandoned the MOPAR accessory unit, that requires you to go the dealer and pay them to use the starscan tool to turn it on) is one of the snap in splices with the rear tail lamps "T" connectors that connect to the rear tail lamp connectors.

My bluetooth Uconnect MOPAR accessory unit, is intentionally disabled plug and play, with an adapter that comes with it for the CAN Bus, just plug in the adapter to the radio harness, and its on the CAN Bus. And with my enhanced scan tool I can tell its integrated into the bus, communicating with the bus controller, I can even run the self-test and it reports back over the bus that it pass's. BUT, it won't work, its intentionally disabled until you bring it into the dealer and pay them to hook up their starscan tool using delaernet (meaning only the Dealer can do it) to just turn it on.

Yes, I've learned since then, you can pull the same unit from any car in a junkyard, that has already been enabled by the dealer, and it will work plug and play, no additional trips to the dealer necessary. So, any argument that its there for anti-theft reasons are totally bogus, as well, any argument that the CAN bus is too complicated to have it configure itself or let anyone but the dealer add something to the Can Bus, all bogus arguments. The only reason I can think they do it this way, is to force customers into the dealers and make money for the Dealerships.

As well, stay away from any of the Mopar Accessories for iPod, google it, you'll find posts all over the web, despite what they advertise, they do NOT work with just about all the iPods and have a lot of trouble with the iphones. I spent money and time to install mine, and it hasn't worked with a single iPod I have tried yet, including a lot of different friends ipods.
