Did you drill through that hole to feed the wire through?
Did you use the 24" extension, or do we need the 48?
Does that 14mm receiver replace the plug's crush washer or do you use both?
1) The bolt hole was there - factory. There are also two down lower, towards the floor boards
2) 48" extension. 24" wouldn't be long enough
3) Instructions state to take the crush washer off the plug, so that's what I did...
