My check engine light turned on and I found this disconnected wire.

I couldnt find any open female plugs. If you own or work on these things could you please look on your full size 99+ GM truck to see where the wire plug and ground connect I'd appreciate it. Thanks.

Check the air cleaner assembly box. Pre-MAF sensor @ throttle body.

well that plug goes into the engine hood light and the ground attaches to the hood(kinda obvious once I saw it).
But as fas as the check engine, no codes scanned yet.
The only symptom i feel is when coasting in drive or reverse(less than 5mph) the car feels a little jerky, like the feel of super warped brake rotors,(possibly fuel pump related?) I need to get codes scanned

What work was done that made this unplugged wiring apparent?

Well, we can rule out any cleaning.

Glad it was simple enough to find, squares. I had guessed air cleaner assembly box sensor since the CEL had come on with no indicated driveabilty issues. I had a Ford Explorer that had short length wiring to the ACAB that would pull out everytime I checked the air filter and throw the CEL - annoying.

Nice to know Chevy/GMC still provide an underhood light. A small, yet functional item Ford neglected to add to the S197.
