They confirmed today however that the WK2 must have the PCM reflashed by the dealer so the vehicle canbus will recognise the new harness.

I don't want to get into any position to compromise the comms and raise warranty issues so your advice to go the dealer fit bar I think is on the mark.

If I actually had the new vehicle to hand I wouldn't spend so much time poodling around on the internet and finding things to worry about.
Its going to be a long four months....

The US bar is not legal for Australia as it does not meet ADR's for us the BB bar is of a higher standard and meets australian ADR's

Hi I'm looking to get a towbar fitted to my MY14 Laredo, but am a little confused about two things at this stage;

Firstly, the local Jeep specialists quote an extra $200 on top of the normal price for 'an ECU' - is this BS?

Also, at vehicle purchase, the dealer fitted a (very cheap) reverse sensor system, and far as I can tell there is no way to switch off the rears - is this likely to mean constant beeping when I have a trailer or bike rack on?

Thanks!

Had a tow bar put on mine at my local tow bar specialist, no mention of extra $$ for a ecu. Jeep wanted $1400 got mine for $750. Surely the sensors would only work when reverse is selected?

Some cars use an ECU of sorts due to the way modern wiring sometimes works. Not sure about WK2 but for example some cars don't have a traditional wire for every light like the old days and the lights trigger from pulses ! Variable voltage and tricky stuff. I'm working on a Colorado at work and brake/tail I notice use a single wire. They have a controller as does the wife's Challenger. As far as the reverse sensors go you can get trailer plug sockets with a micro switch built into the cover especially for disabling reverse sensors. Some factory systems on some brands need this.

2014 WK's dont have the factory connector for the tow harness ,they get wired up the oldschool way by tapping into the tail light wiring , when your trailer or camper is on just turn off the park assist via the switch or in driver assist settings in the radio menu .

I don't have the factory reverse sensors, it's a separate system that only allows the front sensors to be switched off

All you have to do is wire in a switch yourself to the rear sensor power side and your done .
