Tom,<br /><br />I assume this engine has an external trim pump (mounted inside the boat) with 4 hoses that run to the trim cylinders. <br /><br />The trim motor itself is as Ben has said. You should only have a red and a black that run to the battery and a 5 wire harness that runs up to the controls (or a seperate trim control panel).<br /><br />Chris..........
