1988 7.3 non turbo.

I found this relay on the driver side engine bay near the brake booster area. The wires were disconnected on it.

1. What’s it for?

2. How do the wires get oriented in the connector?

Thanks!

If the relay was disconnected you'd have to trace the wires to their origin. Maybe the remnants of an aftermarket alarm... :dunno

I think you are short a few wires for the female connector...
