I have the 10 relay bussmann box. Huge ! I have it placed in the back. Where the OEM jack goes. I heard some people move the abs box and place it in passanger side. I couldn't find a spot to fit it anywhere. Especially when you have a 5speed. Clutch cylinder is in the way. If youu want better pics I can take more
Here are where I installed my breaker for. The other breaker is for bluesea fuse box. Tucked away from water, easy reset acces. Close to battery. Can fit your hand through the hole to tighten on the bolts. I used stainless steel with rubber washers on both sides.
I plan on putting mine in that exact same spot as well this weekend. Lots of room there My 99 had the earlier ABS there and so I didn't have the room but the 2002 does.
