Can I use my USB program from my mp3 on the later type hub.
Unfortunately the MPIII USB programming cable is not compatible with the MP5
(or MP4) as they requires a different USB programming lead with the correct 5 pin connector to plug into the Vector controller's wiring harness, and they also use different programming software.
Also will need an hydraulic brake to mechanical brake sensor. Are they any good?
I have not tried any brake sensors conversions for hydraulic levers so I am unable to comment on either their ease of installation or their operation.
GM Canada sell
hydraulic brake kits that are designed to plug straight in to the MP5 control harness, but I'm not sure if the tubing would be long enough for a tandem rear brake.
