I can hardly wait any longer. This is my first 4Runner!
Mine is on the ocean to the Port of Portland (Vancouver), expected 21 Feb and ready on the 13th…
The circuit at the connector would certainly have two large gauge wires, - power and ground. The brake pedal input and control output wires plus a panel lighting would account for all of the wires shown.
A search near the bumper may reveal one of the smaller output wire.
I noticed that some lower grade models do not have a panel on the underside of the hood. It makes me curious if there are other noise dampening upgrades through the various models.
Your view from the back looks brutal ! I sure love seeing what’s underneath.
I want to interrupt the fuel pump from the interior so I can hide my disable switch. Have you seen the harness, or do you think it travels underneath to the engine compartment?
