Yes, my 2009 does have a steer lock.
The speed sensor is mounted on the back of the transfer case.
i finally got the video up to show the speedometer working.
That being said, I went out this morning to fisically verify it was on the case. “My previous statement was from info I found on line. “. I did not see one, but then again I could only see about 85% of it.
I still think your 2009 should not have a steering lock. Try again to turn your wheel with the key out. My buddy has an 09 and tows it without a key in the ignition.
Must be an early ‘09 vs a late ‘09 thing
My 16 RAM has a sensor built into the transfer case! 8 speed ZF transmission with NP transfer case! Although electronics and computers makes placement optional, the 3 speed torqueflight transmission with NP transfer case, the speedo gear is a sleeve over the output shaft in the tailshaft housing with a removable gear out the drivers side of the housing.
The ability to decide how many beers you need for the evening!I can’t remember what the first thing was.
An early 2008 will have a steering lock. It appears you have a TJ that will add mileage being towed. That must be why you tow a Slingshot!My apologies mine is a 2008. I don’t know why I was thinking 2009???
They say your memory is the second thing to go. I can’t remember what the first thing was.
Anyway the wheel does lock.
We settled on what appears to be a very well-cared-for 2000 TJ. Manual, 5spd 4cyl. It is already configured for toad and the seller handed over the 6.5 Blue Ox equipment as part of the deal. The only thing I'm still not getting from this discussion is if mileage actually accrues while towing. I see that in some instances the speedo operates, but mileage? I'm not always the quickest on uptake, so please excuse me if this has already been explained. 
I did note that when I put the ignition switch on our TJ to the first click forward, no accessories turn on and the odometer display does not illuminate. We'll be taking a test tow later this week when weather settles and I'll know more then. Thank everyone for their input here. It has been very informative.It only added mileage on the video posted because he left the key on and did not disconnect the battery. Most years do not require the key in the on position as the steering does not lock. His model year required it. So, since he left the key on and the battery connected, it added mileage.@BGMAC, @Rollin Ollen - I've learned a lot from this discussion and investigative 'series'.
