Ahh right, if it's clicking when you earth that tag then the tag should be earthed. Not sure off hand if it should be to the battery , But there's only ~5 earth points on a sierra anyway. does not realy matter where they are but on the donor there is usualy one at the base of each front door pillar ( although some cars may not have on on one side) one on the steering column support, one behind each headlight and and perhaps one at the battery ( but I can't remember)
