here is a link for the grounding straps that work the best. if you put ends on the cables they need to be soldered to the cables or what I due in most cases is buy in bulk and cut to length then solder the end of the cable good and then drill a hole into the wire and solder for the size needed to fit the bolt or stud you are going to try it on. now this is used for external grounding only. do not use this in place of a regular ground wire with the power feed. I have seen some where I have had to put a ground on the engine to body and ground the hood to the body. even the doors at times. this is a lot of extra work just to use a cb radio but it takes it to get the ground loop closed up so you do not have the noise. most of the newer vehicles has the ground straps on the engine to firewall and hood. the older ones normally do not or it will break after years and a person will remove it.. hope this does not confuse you too much.
