Recently I've come across some newer installations that have 2 rings or more added onto a preexisting 4x4x1.5" work box.
The reactor would go into box 1, all lights can be on a relay, the two small pumps can be on a relay. So we are down to 6 items, 2 relays, 2 pumps, 1 engine and 1 steering. This will need a second box. If you look very closely inside the box, it should indicate the cubic inches of the box. Please provide this number and we can tell you the number of conductors that can be placed in there. Please note that there are additional considerations, like whether the box itself will have a receptacle in it (a receptacle typically counts as 2 conductors). Join Date: Sep 2000.
