Need recommendation for trailer brake install shop in San Diego, CA.

My 2018 SR5 crew Max comes with the trailer hitch and the connectors but does not have any trailer break control in the dashboard. I bought a Tekonsha P3 to install but it's a little above my paygrade I need professional help to do it right the 1st time, my trip is in a week and a 1/2.
Thank you for the help.

 

Did you buy the vehicle specific wiring adapter with the brake controller? If so it's a simple plug and play, then mount the controller where you want.

I pulled both kick plates from driver and passenger side off, I pulled the undermount of the dashboard where the oem control goes I still cannot find that 7 pin connector anywhere. Also I cannot find verifiably a 2018 SR5 Install video . I bought all the gear for the install but I can't find the plug... I found other plugs but not the 7 prong
