Firewall Junction box wiring question

[jfkelley]

1976 K10 Scottsdale ..I need help with where all the wires go that's on my firewall junction box .I spend alot of time out on the road covering three states and for some reason thought I would be able to remember where they went when it come time for reaasemblej ..When I did my engine swap I didn't take pictures or make a note of where they all go ...I drew a pic what's there now..But I know there are some missing wires...I think there's one that goes to the starter ?..Maybe one to the back of alternator ?...Im not certain that's why I'm on here asking the experts ...Thanks in advance

You’ll need to find a wiring diagram, it will show you every wire on the block…do a search here, and if not search the web.

The wiring diagram will be in cab, and under hood. The wires will be numbered were the diagram goes to the other half. The numbers will correspond to cavity in the bulk head connector

Wiring diagrams are posted in the reference library at www.gmsquarebody.com

Shop manuals are there too. You have to register to view otherwise I'd post the link.
