67 3 hole instrument panel wiring??

Hey guys,

I was able to find an old original wiring harness that plugs into the back of the instrument panel thanks to Outback truck parts. So now to the task of wiring it up from the new wiring harness. I've search the forum and haven't found specifically what I'm looking for. I have seen the 2 different wiring diagrams and am not sure which one is suppose to go to my 3 hole panel. Basically i just want lights on the instrument panel. My Speedo works. Blinkers have been converted to something the strapped on to the steering wheel, which I will address later. And my fuel gauge doesn't work either which im trying to work on as well. So long story short is there a simple thread anyone can point me towards specifically to the 3 hole panel and or drop any knowledge on how to wire up.


Thanks for your help.

The pink fuel guage feed is power to the guage. The tan fuel gauge is going to the sender in the tank.

So in theory I could run the wire from the tank and hook directly up to the tan wire that runs to the back of the plug?

Here is a highly enhanced diagram of the three hole wiring diagram. It is the second post down and the scroll is on the bottom of the post.
