Re: How to make a ground
If you can, nut and bolt the connections and use the star washers on both sides of the panel. Steer away from bolts that thread into the thin sheet metal if you can. Solder the ring terminals to the wire ends and then after making the connections put some dielectric grease over it to help seal out moisture from getting to the connection. On cars at work I sometimes take black silicone out of a squeeze tube and cover the connection. If it ever needs to be checked the silicone is easily removed and if you apply it good you can make it look nice.
If you are adding more electrical devices than what was on the car originally, upgrade the wire size of the ground from the battery to the body of the car. If you don't this smaller wire becomes a restriction.
