I have the two plugs that are near the power steering that have been cut on both my harness and my parts harness..? Do I need them or more specifically what are they?😂 The other two I was able to repair but still curious on what they go to. I was thinking maybe something near the fuse box?

 

top pic, pink wire is Power steering idle up and the second wire is for the a/c magnetic clutch. The bottom picture is for vapor pressure sensor for the evap.

 

are the idle up and a/c a need? Will the motor still run without them?

 

The engine will still run without them, but the steering will not idle up when turning. Only a minor inconvenience when turning while stopped.

The TG Tacoma to IFS steering box kit gets rid of the idle-up valve all together.
