glow plug relay wires
just got a new GPR109 and am curious if where you hook the wires up matters all that much. either wire to either big post? either wire to little post?
there is an I stamped onto one side of the top and an S stamped onto the side.
when the truck is off without key in, should i be able to measure 12v when i test the two large posts?
thanks!

Either little wire to either little post. You can hook up the big wires to either post also, but the relay is marked "I" & "S" so try and put the load wire (the one that is not hot) on the "S" terminal. With the truck key "off" you should only have voltage to one of the big wires.
