we were hoping to get the part number of the connector that is integral part of the module - those connectors are available as a standalone units (check the 12-pin trailer connector that is taped off on the rear wall of the trunk, next to the hole opening for the trailer harness), but it seems to be a very hard endeaviour to source them... removing the pins and direct wire them should work for people whoi already have the trailer module (thus hav ing each individual rear fog fed and monitored by the LCM directly, as opposed to splitting pin 3 of the trailer module), and for those folks who do not have trailer module and have no plans for the trailer module - they will get the rear fog functionality without spending an arm and leg for the tow hitch... those, who have the tow hitch and where the rear fogs are standard - they careless about this retrofit...

I am going to source the 2-pin connector for the application and will let you guys know...

Interesting so did you want me to wait until you source a 2 pin connector then we can have pins 10 and 12 of X609 in their own connection once removed?

I was most likely going to do my own connection with scotchloks or something similar like you said above, a nice male/female connection and not solder it.


And to all who are reading the back and forth, all that Terminator and I speak about is for OWNERS WHO DO NOT HAVE THE FACTORY TOW HITCH KIT INSTALLED AND WOULD LIKE REAR FOGS WITHOUT SPENDING $160 on the Trailer Control Module. If you do have factory tow hitch in your car, please follow the DIY on page 1 of this thread. When my switch comes in (it hasn't yet, I checked the mail yesterday) and I get my rear fogs working I will do a separate thread and put a reference in this one, since the install is for 2 different applications.


Terminator just wondering, whats the best way to pop pins 10 and 12 out of the X609? small thin flat blade screwdriver? Been a while since I switched pins out of my tail lights when I installed the LED's.
