amps gauge Mar 19, 2006 8:47:19 GMT -5 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by 73gmc on Mar 19, 2006 8:47:19 GMT -5 In my 73 gmc , I have an amps gauge that does not appear to be hooked up. Can someone tell me how I could hook it up from scratch, as if no wiring is there at all. ?
