XPLORx4 Posted August 24, 2017 Share Posted August 24, 2017 Buy a universal trailer wiring harness such as this one: https://www.amazon.com/Hopkins-46155-Taillight-Converter-Universal/dp/B0002Q8036 Remove the right rear cargo panel and the right rear taillight. Pull the wiring harness out of the hole behind the taillight to expose the wires. Tap into the OEM taillight wires from inside the cavity behind the cargo panel. Run the 4-wire flat trailer wire harness down and out one of the rubber drain plugs on the bottom of the cavity and zip tie the wires back to the center of the hitch receiver. 1 Link to comment Share on other sites More sharing options...
colinnwn Posted August 24, 2017 Share Posted August 24, 2017 How can i do it without the harness? Any tricks Sent from my SM-G930P using Tapatalk As I remember there is a box you can plug in behind the driver's tail light that has the 4 prong trailer light adapter. Are you wanting to skip that box? Can you just order it, or get one in a junk yard? I think that would be easier if an option.

Slartibartfast Posted August 25, 2017 Share Posted August 25, 2017 You do need a converter box. The trouble is that many trucks run one 1157 bulb in either taillight, with the dim filament hooked to the parking lights and the bright filament running both the brake lights and the turn signals. Four-pin trailer wiring is set up the same so that it'll wire up easily. Pathfinders do not have brake and turn combined; brake has the bright filament of the 1157 all to itself and turn has its own separate 1156 bulb. To connect this three-filament setup to a four-pin trailer, you have to get a converter like what XPLORx4 linked. It should come with full instructions and labeling on the unit itself to make the wiring fairly straightforward. Link to comment Share on other sites More sharing options...
jgrote Posted August 26, 2017 Share Posted August 26, 2017 I agree, you will have to use the converter box. I have the OEM harness, and it still has the box. If you're going to buy the box anyway, you might as well get the plug-n-play version. They are about the same price and make things much more simple. http://www.ebay.com/itm/Trailer-Hitch-Wiring-Tow-Harness-For-Nissan-Pathfinder-2001-2002-2003-2004-/142463058318?hash=item212b75c18e:g:hTAAAOSw3gJZMZNs&vxp=mtr Link to comment Share on other sites More sharing options...
kdj Posted August 30, 2017 Share Posted August 30, 2017 I wire brown,yellow, green and white. What is a "box" for? I have signals, brakes and tail lights. Trucks X2. Link to comment Share on other sites More sharing options...
XPLORx4 Posted August 30, 2017 Share Posted August 30, 2017 The "box" refers to the trailer wiring harness adapter/converter. It takes 5-wire input (ground, tail, brake, L signal, R signal) and converts it to 4-wire output (ground, tail, Brake/R signal, Brake/L signal).

Slartibartfast Posted September 4, 2017 Share Posted September 4, 2017 No, don't say why, or even what--it's fun to guess what you mean. Link to comment Share on other sites More sharing options...
