Following wire on 91 Civic LX

If I am not mistaken, pin 5 of the main relay connects to fuse 14 under
the dash, which gets 12v when the ignition is in the start or run
positions. Well, it seems there is no connection between that pin and
the relay. I was looking under the dash and it seems the wire that
supposedly connect both together leaves the relay, then goes somewhere
by the firewall, if not all the way to the engine bay for whatever
reason, and then possibly gets back to the fuse 14. Has anyone traced
this wire out and can tell me how far into the harness it goes before
coming back to the fusebox?

have you checked the wiring diagram in the service manual? what are you
trying to do? what problem do you have?

This is a black wire with a yellow stripe? It doesn't leave the Main Relay,
it leaves the #14 fuse. It ENTERS the Main Relay from there. It also goes
out to the engine compartment to the EVAP purge control solenoid and the
fuel pressure regulator solenoid. Power for those two solenoids plus the
Main Relay's pin 5 ALL come from the #14 fuse. If one thing's not working,
the others won't either.

Feed to the #14 fuse comes from the ignition switch, specifically IG1 (the
main IG terminal). Got any other electrical problems, such as starting,
stalling, or intermittent electrical operation? Might want to pull the IG
switch and have a look at the contacts.

Here's a good tutorial:
