Should be mounted at the top of the starter
The solenoid is attached to the starter. There is no relay.

Starter lockout relay, next to the battery.
the fuse is next to the parking brake The relay is in the box under the hood near the wipers.
To bypass the starter relay on a 1991 Camaro, you can use a jumper wire to connect the two terminals of the relay harness. First, locate the starter relay, which is typically found in the fuse box. Remove the relay and insert a jumper wire into the corresponding slots of the relay socket that connect to the battery and starter. This should allow you to start the vehicle without the relay, but only use this method for troubleshooting, as it's not a permanent fix.
The fuel pump on a 91 Ford Ranger is controlled by the starter fuse and relay. This relay is located under the hood. It will be located by the fender on the drivers side.

Unhook the battery completly, then jack up the truck take off the passenger side tire, at this point you have two choices either remove the suspention on this side of the truck or be ready for lots of fustration as you wrestle the starter out and the new one in. Unplug the starter relay wires and unbolt the main power cable from the batt. Unbolt the starter and take her out.
It is on the starter itself and is called the starter solenoid. Heavy current is handled by the solenoid which is activated by the ignition switch. Current comes from the igniton switch, then to the s terminal on the starter which then connects heavy amperage to the starter motor itself.
The 1991 Ford Explorer should have a separate starter relay that sends power to the starter. It sounds like the relay has stuck and is sending power to the starter even after the vehicle is running.
