im upgrading the big three on my 94 mazda 626 and i cannot seem to find the positive post on the alt. i have a tear down book and it doesnt really say on there. all i have found so far is a plug that goes in to the alt with i think two wires but they are really skinny looks like 14g. is there a post on my alt to attatch a wire to or is it a plug. if it is a plug how to i attach my big three wire to the alt pos. if it is a plug.
