They won't need more proof than that.
Magnuson-Moss act had one purpose; To keep manufacturers from fraudulently denying warranty claims for frivolous reasons (like: guy adds aftermarket wheels, so denied engine claim, etc).
If OP is worried that they did in fact record the aftermarket alteration (took pictures, etc), then he needs to go back to dealer with wires removed (back to stock), have the whole system tested (maybe pay $100 diagnostic fee) and then ask nicely to have FCA record the fact that all electrical systems work great. Then they won't be able to deny electrics claim in future.
And why would that alleviate the problem in the FURTURE that they could allege was caused by a perhaps faulty 3rd party add on faulted later and damaged the Jeep electrical system.
And what "Test" would they run to confirm no damage is done already?
Do you think they have such a test at the dealer? They might in an RD lab.
You think things are that simple?
One thing that is VERY difficult to test is EMI. Indeed something like a HID system could inject noise into the car causing say errors on the CANBus. And the CANBus handles it fine 9999999/10000000 of the time. But one critical packet corrupted 1 time and toasted the transmission.
How could you prove it wasn't the HID. Or prove it was unreasonable it still shouldn't have failed even with added noise. I'm sure these vehicles are rigorously tested for all sorts of extreme cases. And it gets pretty muddy these days over what caused what even with OEM parts, let alone after market ones.
Or an error could be happening frequently that is causing some part to prematurely wear out. How do you test for that?
I can't really say I blame the Dealer for baulking. Even if they legally shouldn't be. They have enough to deal with, with the OEM systems.
Again, I totally agree legally and likelihood of it being a problem is extremely low. But it is totally possible. And could be due to a weakness or fault in the Jeep that is susceptible to say noise. But they tested their system (with billions of miles of vehicles on road and in the lab) as a whole, not your modified one.
Another big one is the surge the HID's might have when they come on or off. Do they meet the same in rush specs the OEM lights do? They could be better, who knows. Is it Jeeps job to validate 3rd party components?
HID's are a pretty huge electrical component.
