Adding 4-Way or 7-Way to 2002 GMC Sierra 2500HD Without Factory Tow Package

Updated 04/25/2018 | Published 04/24/2018

Question:

Almost an hour trying to find a part on your site. Every time I find one, it tells me it is not for my vehicle. This is ridiculous. 2002 GMC Sierra 2500HD NO factory tow package. Want to add 4 or 7 way wiring to truck. ALL you show is replacement parts for existing trailer plug! EVERYTHING else says it is not for my vehicle!!

Though you may not have the factory tow package, almost all GM pickup trucks like your 2002 Sierra 2500HD came with the factory trailer wiring. You mentioned you have an existing trailer plug, which you can use to install the Multi-Tow 7-Way and 4-Way Trailer Connectors # 30955, which will plug into the OEM connector above the spare tire.

I've added a couple links to video reviews for you to check out as well.
