Put this on the wrong site before. Sorry. I have an 83 bonneville wagon. 231 v/6. Traded the carb and distributor for pre ECM models from an earlier year. Now the convertor does not lock up. I've been told I can wire a direct or toggle switch 12 volt to the trans switch and revive the lock up capability. If I can do this,to which wire do I tie into to? The trans plug in has 2 wires.The trans I'm told is a 350C.
