Re: 1969 johnson 25hp tiller to remote
think you mean the two lever Simplex controls, compared to other two lever controls. Simplex controls are easily available, particularly if not too fussy about period. If you find one of the OMC Simplex models (Johnson, Evinrude, Gale/Bosun), you should be getting the correct engine-end connectors with the package. (I'm assuming the '69 has the same control points and takes the same connectors as the '50s an earlier '60s, but will do a mea culpa if wrong about that.) Look on Ebay for sets, and take a close look at connectors. There are a couple of differences, but both types work with the engine clips you probably have on the motor. If not there will need those too.
