I have a 1981 cj7 and I cant find where i connect the wiring to it, i have another cj thats a later year i am looking at and i see where its connected, but when i go to look for mine, its not in the same spot and i cant really find anything, is it somewhere els eon the earlier models? and also i have a yj tub that its mounted too, could it possibly be that the part of the firewall there is a bit different from the cj which is why i cant get to it?
