89 200 tq idle stabliizer issues

[Robert Beatty]

trying to troubleshoot my idle stablizer valve circuitry.

Looking over the wiring infomation I have, it says to check at the aux relay 
panel pin 14 (socket 11) and pin 5 (socket 12).

I cant find the ISV control unit.  On the 5k its under the dash on the right 
hand side in relay panel 1.  Its not there on this 89 200.

Where else could it be?  I have the lower dash off on the drivers side so I 
can see relay panel 1.  I havent found relay panel 2.

Anyone got any suggestions on where to look for this sucker?

Thanks
Rob
