Does anyone know why some models have this round starter relay instead? Is there a difference between the one below and the first one I posted that is more of a square shape?



This round one is the relay my truck came with, but the large terminals are just too close together. After nearly jumping out of my skin for about the third time this year because I accidentally bridged the two terminals and the starter began spinning, I would like to switch to the other style shown in my first picture. Will there be a problem doing that?
