What did you do to your JK today?

Not sure if this is much help (mine was a TIPM problem) but lots of trial and error here:

I'll try that. I got a pack of fuses, just waiting for my PCM to come back from Florida.

In some ways it's sad, I gave my 2014 JKU 10 years and 116k miles of care & feeding, and now it's time to move on. She's for sale.

So put my PCM back in, replaced the M27 and M28 fuses like WranglerFix suggested, still no joy. I can't even get a code off the dash using the turn key method (It's all dashes and then says DONE after several seconds). At this point I can only conclude, with the knowledge that I have, that it's a wire somewhere. Gonna have to set time aside to hunt it down.
