You really have only 1 "starter relay" and it's in the fuse box (it has replaced the big clunky thing on the pass fenderwell in older versions of the truck).
What's on the stater itself (and the ALL have this) is the Bendix that is both a solenoid for the motor and the actuator for the gear in the starters nose to go forward and engage the flywheel/flexplate.
So, if you jump those terminals (and you're sure you're getting a solid connection) and it goes "Click-click-click" as you do it, it's gotta be the starter that's at fault. OR, you've got crappy connections in the battery terminals (less likely, but clean, grease, & tighten them all, Both sides, to be sure).
