Dog head relay say's 12V on it ???????

[Drock]

Hey guy's I've gone over the sticky's and didn't find an answer for this one. Before I found this site I saw ah video on you tube on how to do the dog head relay mod. In the video the kid used part (Oregon#33-431). So I ordered one off the interweb and when I got it had 12V stamped on the side. Is this the correct one or is this for if the truck is converted from 24V to 12V???

Well, yes it would be. The signal is the 12V from the ign key as a civilian chevy would have. The two terminals it closes are the 24v side.
