Hello,

I've had my 2005 Nissan Frontier now for a little over a year. I tow a trailer almost everyday for my detailing business. A week or so ago, I saw an arc at the 4 wire connector on the truck as I was connecting the trailers 4 wire plug into it. The lights then failed to work. I've replaced the rear harness on the truck with a OEM harness as well as the OEM harness in the kick panel in the cab. I've also completely rewired the trailer. The lights still don't work, except the right tail light of the trailer. Looking at a schematic of the Tow section of my truck is a nightmare., and thought it might be just as easy to splice in a tail light harness, like I have done in 2 previous trucks. Since my trailer is just 2 lights and I need running , turn and brake lights seems simple enough. My question is will splicing into a tail light ruin or mess with BCM (body control module ) or will it be ok ???

I'll appreciate any help !

Sounds like you could have already messed something up in the BCM. First check everything on the truck and then all the relays in the kick panel on the passenger side and the relays on the driver's side rear under the bed. I don't recommend splicing into anything due to the BCM, as well as corrosion.

I'm guessing you have the diagrams of relay locations unless you paid to have the two kits installed. The relay combinations are different for manual and automatic transmissions so let me know if you need that information.

With all the various electrical towing issues with the 2nd Gen Frontiers ('05-Up) it seems best to use the OEM kits rather than saving a few bucks and having a place like U-Haul send you back to the dealer after "they" screw it up.

Every '05 I have done (including my own) has used OEM kits with no problems so I can't really comment on the specific issues related to after market kits, but I will say that I find it quite common to end up back at the dealership. Also, a bumper relocation for the connector is the way to go if you haven't done so already. Good Luck, Z
