Starter Solenoid Switch Relay E9TZ-11450-B | Ford Mustang F150 F250 F350 | SW1951C

If your Ford clicks but won't crank, the starter solenoid might be the problem.

This is a direct replacement relay, matching OEM numbers E9TZ-11450-B, E9TZ11450B, and superseded numbers like SW1951C.

It fits a massive range of Fords—Mustangs, F150s, F250s, F350s, and more from the late 80s through 90s.

It's the square relay that mounts on the fender well or firewall, sending power to the starter.

It's a new unbranded unit but built to OE specs.

Interchanges with SS598, SS613, SW1533, SW1951, and 3381.

Easy swap—just disconnect the battery, move the wires, and bolt the new one in.
