Finished putting my truck back together and it runs great, but I don’t have any lights (interior or exterior). Went through the whole troubleshooting process and found that my wires are good (continuity tests passed), but I’m still not getting power to the headlamp switch. I think I narrowed it down to a faulty “s” terminal on the starter since I can jump the two s terminal wires to the junction block on the firewall and I kinda get headlights (see pic below). Just wanting a sanity check that this is the issue. I also drew up a bare bones wiring diagram from what I’ve found

You have the wires on the starter wrong. The fusible links and the battery cable go on the large post,only the solenoid exciter goes on the s terminal

For everyone's benefit and to save troubleshooting time,a fuse will not take out headlights on a factory wired Squarebody truck. They get power from an under hood fusible link at the starter and by the headlight switchbitself which has an internal circuit breaker.Dash and taillights are fused.
