With it being in a van it is a pain in the rear trying to see anything on the front of the motor but I will look further for where it needs to hook up to. I am going to plug it until then. I went out and did a small job with it a little while ago and the light did not come on until I pulled back in ( of course I forgot to plug the hose before i left) Good thing was there were no 300 codes this time and it ran really good. Gonna let it cool down some and check some more for the other end of that hose connection and will plug it off if i can't locate it then go for another ride.

Most women like the strong, silent type… Fortunately for me, my wife prefers the out-of-shape, mouthy type.
