Do you have the 2.1 version which has a pink wire loop inside each wire loom?

If it is a plug n play model with no pink wires, it will only work with the car style 90mm.

If it is the 1.0 version with the long pink wire that you connect to a 5V reference, you can get it to work with the TBSS TB by connecting a jumper wire between the 2 grey wires on either end of the unit.
