Default Uf10/uf11?

I kno this has been covered before some where but iv been looking and every time i search using Google i get ufc results lol... anyways if my vin has UF11 in it should Air ride? I was redoing my trunk the other night and noticed theses two power cables on each side just about where the strut would sit at.... but far as I kno if i where to have air ride I would have switches near my shifter, and another thing i noticed was a black box under the hood on the passenger side the read "air ride" or something along those lines. I lifted the cover and seen that there was only a fuel pump relay under there..... any input would be very helpful

There's a reason for that, C is not supposed to be in your VIN #.
J=Japan
T=Toyota
8=Passenger car
U=1UZ-FE 4.0L
F=LS 400

The chasis code which is either ucf10 or ucf11 ( 11 = air suspension) is located on the firewall somewhere.

sweet, thanks you sure do know your stuff, im just wondering why the previous owner went out of his way to make the car look like it was never air ride.... I understand how much more cheaper springs and struts are but for him to delete all the switches also hmmm
