I'm changing my fuel pump relay in my 86 2.8l firebird. I noticed it can be rotated and plugged in either way. There are 4 pins connected in the plug to the 5 pin relay. Does orientation matter? I swapped the dead relay out with the MAF a while ago and didn't realize this back then so I'm unsure if it's the correct way.

Edit - never mind, I'm stupid. It doesn't fit both orientations. I just assumed based on looking at it. There is a plastic protrusion on the side preventing the problem above.
