This is topic of much heated debate in these forums, whether or not XE model Titans are prewired for a brake controller. I posted a thread, actually my first, and it pretty much went no where as far as responses go or any solid advice. Maybe folks were sick of haggling over the issue, whatever, in any case here is the the deal with the XE's. They are prewired in every aspect for trailer brake controllers except Nissan doesn't run the nice, convenient connector under the dash, they leave the wiring behind the driver side left floor kick panel. I had a very reputable RV center do the brake control install and it only cost about $90, parts and labor. Maybe that's not as cheap as just as the plug and play pigtail included with the LE and SE models, but $90 is alot cheaper than a full wiring job by an RV/auto electrician. One of the two fuses you get with the factory ordered class III hitch package (the only class offered by Nissan, there is no class IV, only the class IV weight distributing ball mount, not the bolt on tow hitch, trust me I ordered a class four and Nissan sent the class IV weight distro ball mount, that's how I know) is for fusing the prewired Battery AUX line, a nice feature as the battery power is disconnected when the ignition switch is turned off. All things being equal if you get the OFF-Road package with the XE, as most people with an XE seem to, you get the same rear-end in the LE/SE Big -Tow package. After all is said and done the only real difference you don't get would be the heavy duty battery(big deal) and the telescopic side view mirrors(nice). Everything else on the XE is the same. All titans are oil cooled and transmission cooled so that's a huge towing bonus. Only wanted to post this info as I felt there was no clear-cut info on XE brake control wiring.
