Trailer Wiring question

[chrs93]

I have a 90" XJ and I need wiring diagrams for turn signals, brake,tail lights, etc. to wire up my 4 wire wiring harness. I went in search of a T connector harness and apparently they dont have them for pre 90' xj's. Any help would truly appreciated.

I didn't go into detail, but I believe that the series 70 is the XJ. This is from a '89 manual :

I don't know if this helps. But on my 96 it was behind the interior panel, behind where the spare tire mounts. Right about where the fuel filler neck is.
