I have a 1986 35hp 2 stroke. When I bought it the seller also gave me Mercury Autoblend. As near as I can tell This is an external oil injection system, but I can not figure how to hook it up. <br /><br />There is a hot and ground wire, and a Fuel in and Fuel out. If I hook the leads right to the battery with out any oil, an alarm goes off. That makes sense it would be a low oil alarm. <br /><br />What I am not sure of is where to hook the wires. If it is only an low oil alarm, I can hook it to the battery, but I do not know if it runs any pump inside of the system, If it does, where would I hook it up to?<br /><br />Then there is always the question, should I even use it, or should I get rid of it, and premix.<br /><br />Thanks in advance for any help
