Hi , I am A Brit And have just completed a rewire and conversion to Digital Control for a USATrains G Gauge BigBoy. I have a quiery regarding the four sensor units which are connected and wired into the engine. My control system comprises a ZIMO MX695KV engine decoder together with a Pheonix PB11 sound decoder and all sounds are triggered via speed (voltage) initiation in the controller. Since the sensors exist it would be good to utilise them to trigger sounds. Can anyone advise what each of the sensors (cylindrical 2-3inch long encased in a tube) which are sited as follows: 1) A- the wiring emerges together with the front pickup wiring in the forward part of the engine. 2) B- the wiring emerges together with the rear pickup wiring in the rear portion of the engine. 3&4 C&D) - the wiring for two sensors emerges on their own from the centre portion of the engine Any information would be appreciated Pommanz (Mike Lisle)
