My 2.5 TJ isn’t running well, new engine but it’s having some electrical issue. The code I’m having is P1391 and I found this disconnected, please look at the images. All help is appreciated. Thank you.

The missing under hood light that connector plugs into might help you find the problem.

Normally yes. But it doesn't have to be.

The LED version would be preferable to the OEM incandescent one. I have shattered the bulb in mine several times when hosing the engine and getting cold water on the hot bulb. I have since learned to unplug the light before reaching for the hose.
