Random relay, do you know what it is??

There is a blue relay behind my ECU, Ive always wondered what it is since iv done my swap. It basically comes from the fuse panel thingy in the engine bay through the wheel well. then all they way back…:confused:

Its in a 1992 hatch. If it helps car had no abs no hicas… i think it might of been converted from auto to 5spd…

Any idea?

not sure what it’s for but it’s on my convertible attached to my cruise control computer i just assumed it was part of that.
