1984 OMC 800 Series drive - 1997 Chev.5.7 liter 260 Hp w/ electronic ignition - neither of which were original equipment in my 20' Grady White (1980).<br /><br />I was the the first operator of this boat after the engine outdrive change from the originally supplied 4 cyl. engine. Shifting into neutral from either forward or reverse was impossible and after some internet research it became apparent that this set-up needed the shift interrupt / ESA <br />installation. I've found and purchased the correct shift converter box and the ESA module however I've not been able to find any information on the wiring connections. I understand that with the new ESA modules it's no longer necessary to use the second switch on the shift converter box. Can someone steer me in the right direction here !<br /><br />Thanks<br /><br />Jon<br />jth737@verizon.net
