I think a 52 pole rotary switch could be a little unwieldy indeed
but i'll check them out too. I cant just unplug and replug as the ECU
pinouts are very different. I'm currently trying to find some male and
female ends to match the ecu ports but i think they are specific to the
ECU and so i might have to resort to getting a third ECU and rippign it
apart for the connectors lol.
