Napa GPR109 install

I had to install a new glow plug relay. I got the NAPA GPR 109. Is there anyway to install this thing wrong? I mean there are no markings for the wires as to which one goes where. IT is rotated by 45 degrees for mounting.

Any help is appreciated.

put the wires in the same place as they were on the old relay and you will be fine

Large wire to large post and small wires to small posts, I went through two 109's in one year and finally moved up to the Stancor relay. It is quite a bit larger but it fits fine, and it is made far superior to the 109, 110 or Ferds relay. I highly suggest ordering the Stancor model as you ought to carry a spare GPR just like a CPS, especially in cold climates. I believe the # is 586-902, two years so far and she fires right up every morning. There are many way up North that got tired of replacing the smaller GPR's and have also been very happy with the Stancor model.
