Interesting point. I am not used to having movable relay blocks, coming from a Mazda background (where we have a quickie jumper wire in the diagnostic connector to run the fuel pump which would have not required this exercise, then again, having a proper OBD-II diagnostic tool, I should have been able to do the same).
OTOH, I did search quite a bit and there seems to be quite a bit of disparity of relay locations across the years and models and it would have made a lot of sense to identify them inside the fuse cover with the same painstaking detail they did for the fuses!
