Default Part Identity

Greetings to All, Happy New Year!

New guy here, looking for some help toward identifying the part pictured that I intend to order online. I did a search for the part # but I always end up getting images of the whole lock cylinder housing rather than jus the part pictured below.

Any help greatly appreciated.

'Googling' 26099581 shows it is a ignition lock solenoid ... it might not be sold by itself.
Context is helpful. It sounds like you just found a part laying around in the street and want a new one

Check The Shift Interlock Solenoid!


Hummer has a safety feature to make it idiot-proof. When parked, shift the floor shifter farthermost forward, rotate ignition key to the off position and remove. Done! Failure to perform above, could cause your Hummer to roll away.
