You can look in the Chevrolet service manual, which includes the wiring. Or it is posted online as a really nice generic 67-72 diagram here: https://67-72chevytrucks.com/vboard/...27#post9186727
If you have any questions about the diagram or if you run across something that appears to be unique to GMC that you're wondering about, you can post a question in the electrical section.
