Unless you can find an old (maybe "new old stock") Becker, there is nothing out there that would be LITERALLY "plug and play". I could be wrong, but I dont' think I am. (And I doubt you'd find one to match the dash).


But in any event, the factory heads had the usual power connections (Battery, Switched Ignition, Ground) and the input from the ICM to drive the backlighting (which I did not use) and the 8 lines to the speakers-amp. I fail to see any reason to try to wire to the speed or reverse indication - so it need not be that hard anyway. Just don't use 2 volt outputs, use 4 volt outputs OR the speaker outputs to drive the amp and I'd think you'd be fine.
