I found this pic from an earlier OGR thread. It doesn't have the exact info you're asking but if you look at the white arrow, the wires going to the board at your locations 1,2,3,4 appear to be Black, Red, Yellow, unshown.
So by inference, I'd say 3=YLW, 4=WHT.
The pic is from a teardown where I drew out the electrical schematic. The WHT and YLW wires control up and down. So if you get them backwards it would just mean the gates go down when they should go up and vise versa. That is, you'd just have to swap the wires.
