also go over the ganged earths plus ganged 12v feeds which are behind the grill tucked up by the bonnet catch. these are horrific bullet connectors set up
One tip regarding those old fashioned bullet connector ganging sockets, or even single bullet connector sockets. Before assembling the connections in these sockets, I always try to fill the socket with a squirt of silicone grease straight from the tube.
It can make things a bit messy to hold, but for those connectors just behind the front grille, it sure keeps the water out.
