We don't build the hub adapter harness with the panel lighting wire (pin 2 on the new hub's 8 pin connector), since there isn't anywhere (nearby) to grab the signal... (Trailer brake sw is the closest point)
The pin 7 issue mentioned in post 5 (please follow the link and look at the pictures in
post 40 of CircuitGuy's thread), is when mixing a 2018/classic console lid (with factory hub) into a 2013-17 truck and
deals with the 8 pin console lid connector under/behind the rear panel of the console below the hinge.
>> For that situation only, 13-17 truck console wiring has +12v from battery at pin 7 of the lid connector to run the 12v outlet in the old lid (next to the 13-17 hub)....
>>> On 18/classic wiring, pin 7 of the console lid connector has the panel lighting signal for the hub (& no 12v outlet).
>>>> So, if you plug in a 2018/classic 8pin console lid connector into the 13-17 truck's console wiring, you end up with +12v going to the 2018 usb hub backlight ... Which will be on constantly and drain the battery.
** Side note, If I recall correctly (I don't have a 4th gen anymore to check), when power is first applied to the USB Hub, it will light up briefly before looking for the panel light control signal (even if one isn't present).
It's possible something is waking your truck up randomly or there is an intermittent issue with power to the USB hub.... A customer of mine recent had a faulty/blown fuse in the PDC for the usb Hub.
