Temp gauge questions

[WadmalawJoe]

I have read through several postings on the gauge and problems. I think I have a different question. The PO removed the old sensor and wire and installed a aftermarket gauge attached below the dash. My main question is once I put a new sensor in, where does the wire go to?

Here is the back of the gauge, everything looks ok there, I think;


jeepers, is the picture big enough? lol

Looking my wiring over I discovered something else. I think my dash cluster maybe out of a 67 (my truck is a 69) The first picture you can barely see the 67 in the circled part, but you can see it in the second picture. Maybe, its just part numbers, but it seems odd to me.
