Question:

Trouble finding 4 port harness plug under dash in new sierra 2018 1500 pickup. Is it in lower junction box or under dash somewhere? Thanks if you can help.

The brake controller install harness part # 3016 is the correct harness for your 2018 GMC Sierra 1500 for installing the P3 part # 90195. I attached a picture that shows the junction box and port where it needs to install as well.

I attached an install video for this harness on a similar Silverado.
