Re: Wiring Diagrams Needed
The Haynes manual #412 49-86 Cj's has wiring diagrams. Sorry I don't have a scanner or I would hook you up. I could do a xerox(?) and mail it to you if you want. The junction block you mention is for the headlights and parking lights. Working from rear to front: 1st-One wire from the dimmer switch(don't know if it is high or low beam), one wire to the left headlight and another to the right healight. 2nd-One wire from the dimmer switch(high or low) and again one wire to the left headlight and one wire to the right. 3rd-One wire coming from the main light switch, another wire going to the left parking light/turn signal, and another going to right parking light/turn signal.
What this boils down to is one is for hi beam, one for low beam, and one for the parking lights(small filament on the double filament bulb). If you have the fender mounted running lights (can't remember if 70 does or not!) then the diagram shows the wire that goes to those comes off the harness between the grill mounted parking/turn signal light and its plug, where it goes into the harness, so it shouldn't be an issue when wiring the junction block. Hope this helps some, if you need clarification on anything let me know.
