Purchased a used PC-III; it didn't come with the 9-volt power cable. Connected it to the bike, shows the serial number, but I get a "device not recognized" error and can't download maps. Would rather mess with it connected to the desktop. Anyone know which pins provide the 9-volt power on the serial connector..trying to eliminate my laptop from the equation?

 

Easiest solution would be to give Dynojet or Fuelmoto a call and have them ship you the adaptor.
I used to be able to run a cable out the window from my computer to my bike.

 

I emailed Dynojet and they quoted me $12 for the 9 volt adapter. It's just a plastic plug and 2 wires - wish I had a schematic so I could make one myself.

 

Can someone look at their 9-volt adapter and tell me what pins provide the 9 volts? Thanks.
