Whatever the protocol - I'm pretty sure that it was ALDL - it was compatible
with the older Tech 1 diagnostic tool, as Opel produced an adaptor which
switched the 4 diagnostic leads on the new 16-pin connector to the Tech 1's
single diagnostic channel in the older 10-pin connector. So it seems 90%
certain that all four of the new pins used the same comms and application
protocols that were standard in the Tech 1 tool.

hmm, I was always thinking that Opel/Vauxhall car engines are
using J1850 VPW protocol on pin 2, not ISO... So what the hell is
the protocol used by X16XEL engine (Multec S system) fitted to Astra
1.6 16V ??
