Wiring diagram for Suburban 70 GMC

I am in need of a wiring harness diagram for a 70 GMC SUBURBAN.

I need to figure out what is causing my tail lights not to function as well as my hazard lights.

Just replaced all lamps, checked connectios at tail lights for continuity, replaced headlight switch.

wanting to disconnect the rear wiring harness and see if the issue is in that section of wiring or if it exsists somewher else.


PS: does anything to do with the tail lights go into the colume? I did some colume work a few weeks ago along with some other under dash stuff which is when this junk started.

Thanks,
Thomas
