My mercontol remote from my 1970 Mecury Thunderbolt Ignition 650cc 65hp .. Has a little plug thing opposite the ignition. It is around the same place just over on the other side and i do not know what it is for the holes kinda look like this<br /><br /> / \<br /> ___ <br /><br />or <br /><br />| |<br /> _ <br /><br />I also have an hours meter and other items which i wan't only to be turned on when the engine has been started so its not draining power beforehand! How do i do this?
