Ford Mercury Constant Control Relay Module (CCRM) – F6SF-12B577-AA (Used)

Here's a used but fully functional Constant Control Relay Module (CCRM) pulled from a 94-97 Ford or Mercury.

It's got the part numbers F6SF-12B577-AA, F48F-12B577-AA, and others right on it.

This is the 24-terminal unit that controls things like the cooling fan, A/C clutch, and fuel pump.

If you're troubleshooting an electrical gremlin or just need a replacement for your project, this is a good, tested working condition unit to get you back on the road without buying new.
