Today in our 2012 Nissan Frontier, we'll be installing the tow ready T1 connector part number 118263. First, we'll need to locate the manufacturer's plug located on the inside of the drivers side frame rail. As you can see here, there are two plugs. We are going to remove the cap off the gray plug. Now with the cap removed we can go ahead and take our new inaudible harness and plug it directly into the manufacturer's wiring. As we install our plug we'll make sure, we have it firmly pressed into the connector and locked in place.
Now with the plug installed we can go ahead and run our wire over to the center of the hitch and secure it with some black zip ties. All right now with our wires secured we'll just go ahead and take our side cutters and cut back the excess in the zip ties. Now this will complete the install of our new tow ready T1 connectors part number 118263 on our 2012 Nissan Frontier.

The part that I purchased is good. The harness fits and seem to be very good quality. My Exterra had the connector in the back to plug into. I thought that this harness was all I needed to make a connection to a trailer. After connecting the harness I only had turn and break lights. I did not have running lights. I needed to purchase a receiver hitch tow harness kit from nissan (part # 999T8-N5005). This kit includes the relays that are needed to safely run the running lights on this car. Wiring into the running lights as a shortcut can cause damage to the computer. 15330
CAN U RUN THE PLUG WITH OUT [RUNNING LIGHTS ].OR WILL IT DAMAGE THE SYSTEM. AND WHAT WAS THE COST OF THE RELAY KIT FROM NISSAN $$
comment by: BYRON Z - 12/4/2012
If all you are missing is the running light function, you will need one additional relay to activate the running lights. That single relay is part 38666-1

I received my Hidden Hitch and OEM wiring harness for a 2012 Nissan Frontier faster than expected as I took advantage of the free shipping. The hitch bolted right in place with no difficulties and the wiring harness fit correctly. I haven't had a chance to use either as yet but I'm confident everything will work as expected. When I purchased my new truck it was the truck salesman who recommended etrailer to me and I am glad he did.79528

Had a little problem taking the plug cover off the factory installed wiring harness on my Nissan. But once I figured it out, the new harness snapped in beautifully. I used a couple additional ties to keep the wiring harness tight to the frame. Good purchase.30051
