I think it\'s a box that has something to do with the emissions control system.

Yes, it\'s basically an ECU.

What\'s inside I\'ve never found out but it must be hellish reliable as I\'ve never known one that\'s failed. It\'s shown in Haynes connected to lots of underbonnet solenoids and relays that affect emissions.

Maybe, because the 1st Gen is only a visual emissions check, any faults in the ECU can stay just that - faults - I don\'t know.

No one has ever asked for a replacement for one Vin and so far as I know the old boys on here like me have just looked at it, scratched their heads and put the carpet back.

Choke magnet and choke relay seem to be connected into it. I suppose you just have to remember to push the choke in.

Otherwise coasting valves/anti afterburn valve/ relief solenoid valve.....all shown connected but what the hell happens if they\'re not connected I don\'t know.
