My new toy for this winter 1974 Scamp

OK there is a grommet in the fire wall just left of the brake booster that has two holes in it one bigger than the other, I think this is where the washer hoses go in, water supply in through the bigger hole and out smaller hole to squirters out. What kind of connection is made inside the fire wall if this is what this grommet is for and what does it look like. Also just above the ballast resistor a little to the right are two off set holes in the fire wall, is there some kind of relay that goes there, if so if any one has a picture of it please show it and what it is used for.
Thanks
Bob
