WTB: PowerExtender output cable for T series

[joester]

I was given a PowerExtender (Car/Airplane power adapter) and wondered if anyone has or knows where to get the T series output cable for it.
The power output is cable dependent, and I have the output cable for 355/360/755/760 series TP's. Snipping the end off and changing the plug won't do it, since the TP feeds a signal back to the power brick to regulate the voltage for whatever series is connected.

The manufacturer is apparently out of business.

Thanks.
Joe
