If you look up in the back of the pump area by the hull there is a small threaded hole that plug screws into. There is probably a threaded plug of some sort in there now to keep the water out. You are also going to need the actual electrical plug those wires go into. I cant remember if you need the male or female. I think the male end. I found one for like 3 bucks from someone here. I found out though that BRP uses standard GM plugs. You may be able to find them at an auto parts store. Then if you push those little end prongs into the plug and need to take them back out, you need a special tool. I found it on ebay for 8 bucks. You might also find it at an auto parts store.
