10 P- Position sender - Ignition, TDC Sensor
11 50 Starting pulse for starter

Sorry to be bothering you all with this however I got my remote starter(piece of 30a wire with a 30a fuse in the line) to work with the diagnostic socket -

Im pretty sure that its the same for both kinds of 15 pin sockets, and the 20 pin socket and its very cool!!!!

I wonder what other stuff we can do with this socket,,,

Just jump 11 and 14 and there you go, i look forward to using this the next time i adjust my valves!
