2UZ starter harness questions (1 Viewer)

[woytovich]

I am looking at the harness that runs to the starter on a 2UZ engine... there are 2 connectors on this wire in addition to the battery cables. Can anyone tell me what they are for? Are these simple the power source for the rest of the truck? See the video for context.
Thanks...

I want to say there is a temp or knock sensor up in the value next to the starter

Should be good now... sorry 'bout that....

Is that from a UZJ100?

Yes

The black connector goes to the ECU harness assembly.

The white connector goes behind fuse box, connected to a harness that is routed to the cabin.

two knock sensors, one on each bank

I am sure those 2 connectors are not for knock sensors. You will agree if you watch the video.

The grey connector is the trigger for the starter.

The black goes to the 2 sensors under the intake manifold.
