Parts Needed to Install 7-Way and Brake Controller on 2002 Isuzu NPR
Question:
Hi. I’m want to wire my 2002 NPR diesel truck for towing a trailer with a 7 way plug. I also would like to add a brake controller. It did previously have a 7 way but the wiring was sketchy. I’d like to do a complete plug type setup. Thank you

To install a new, fully functional 7-Way connector on your 2002 Isuzu NPR you will need to start by hardwiring a 4-Way harness. There are not any plug-and-play harnesses available for your particular truck.
If your truck has turn signals and brake lights that run on the same bulbs then I recommend the Tekonsha # 18252. If the turn and brake signals are on separate bulbs then you will use the Tekonsha # 119178KIT instead. This kit includes the converter that is needed to combine the circuits to make them compatible with standard trailer wiring.
Then you will use the Universal Wiring Kit # ETBC7 to convert the 4-Way to a functional 7-Way. This kit includes all the parts needed to do this along with the extra wiring and circuit breakers needed to install a trailer brake controller. I have attached the complete installation instructions that you can take a look at. You may need to add Extra Wire # 10-2-1 due to the length of your chassis.
For the brake controller itself I really like the Tekonsha Prodigy P2 # 90885. This is an excellent proportional controller that will activate the trailer brakes at the same time and with the same intensity that you apply to them in your truck. I have included a short video demonstration and the manual for this controller that you can check out as well.
