The the new hall effect PB-6 throttle box clone has arrived from China. I have installed it on the truck and made the wiring changes to the controller board.
It came without a datasheet of any kind so I had to wire it by trial and error. If anyone else buys one of the ones off eBay the wiring for mine was:
+5v - Blue wire
Signal - Black wire
Ground - Brown wire
Measured voltages are:
Zero Throttle +0.20 volts
Throttle contactor closes +0.20 volts
Max throttle +3.95 volts
There is a small flat area at the low end before voltage starts climbing which is why 'zero throttle' and 'contactor closes' voltages are the same.

Please send me some spread spectrum code
