Wiring help neded

[engairuph]

Learned a lesson today that I have a 69 suburban and the 71-72 will not work. I have a 8 pin connector for my tail lights, dome and cab lights that the later do not. Looking over the schematic I also have a different wiring color code line up in the 12 pin connector for the cluster with gauges and even different for the 71-72 suburban's.
What I need is someone with 69 suburban and gauges that could tell me the color for each pin #. I have the schematic and not matching up to either year.
Thanks
