Wiring Question / Dangling Connectors

[MustangOwl]

I’m trying to solve a “no CEL, cranks, no start“ issue, and while tracking down grounds found two dangling connectors on the wall of the driver’s side panel under the fuse box. The one with the yellow circle is a two-wire connector with black and red wires. The one with the red circle is a 6 wire connector with 5 wires. Anyone know what these are for?? I can’t find any mates! Any help is much appreciated.

You have a FJ62. Follow the FSM for diagnostic tests.


FJ60 has this:

The connector you circled in red is plugged into a box below the emissions computer on the FJ60.


FJ62 has this:

The connector is left hanging on the FJ62.

Clear as Mud.
I searched both the FSM emissions manual as well as the body electrical manual and couldn’t find definitive answers.

The other connector is a mystery to me, unless it is for the door courtesy light switch.

Perfect. Thank you so much!

And yeah. Headed to test the ECU tonight or tomorrow.

Adding this picture to clarify that connector on the 60 is to a ‘relay cleaner control’ which I believe is for the headlights. The 62 does not have this feature (or is it a bug?).

I hope you have figured out the CEL / no start issue.

THANK YOU!

signs beginning to point towards ECU. Trying to FIND and to check all the grounds.
