2008 Infiniti ex35 trailer wiring harness installation

After looking for information without success, I ended looking by myself, so after spending a lot of time checking all the wires, this is a few pictures of the (working) result.

You need to remove the luggage rear plate, the luggage side finisher and the lower luggage floor spacer (INT-34 from http://www.nicoclub.com/FSM/EX/2008/)

I installed this power module : http://www.uhaul.com/MovingSupplies/Wir ... wer-Module and this trailer hitch : http://www.autoanything.com/towing/73A3 ... 11353.aspx

Yellow on green : left turn signal
Green on blue : right turn signal
The black wire coming out of the bumper is connected to the battery.


This is how to fix the ground :

Installation overview :

Brown on red : Tail light
Red on green : Brake light
(Fixed on the left rear lamp connection)

I hope it will help a few of you.

I know that this post is 6yrs old but is there any way to resurrect these images? I just acquired a 2008 EX35 and want to be able to tow a small snowmobile trailer. Already have the hitch mounted and am struggling with the lights. I spliced in the tail lights and stop lights but am trying to figure out an easier way to get the turn signals than splicing into the bumper mounted turn signals.
