My '76 Gran Fury 360-car "had" one. As I was cleaning up the engine bay wiring, I disconnected it, pulling some terminals out with it. I'm not sure which cars came with these and which ones didn't. The '74 Imperial I pulled the "new" 440 from didn't have one, neither did a '77 Royal police car I recently worked on. It has a part # stamped on it, 3843295. It is mounted on the firewall, just center of the ballast resistor. It looks very similar to the AC clutch relay, but the connectors are slightly different. Haven't been able to track one down from my usual sources. If you happen upon one, let me know. Thanks!

It's long shot but try a dealer, there are still parts for these cars sitting on shelves. Dealers can do a part number search and see if there are any in other dealers inventory. Also collectorsautosupply.com

I work at a dealer and just ran the number, it is saying it is not a good number.

Is this a street car or your race car? Two years ago I was pretty proficient on how that worked as I had to do a fair amount of work to the charging system on my car when installing a 76 wiring harness into my 74. The primary purpose of the field and load relay is to disable charging during engine cranking and start up. If you study a diagram, when the starter relay is engaged that opens the field circuit to the alternator. It can easily be bypassed, if this is on the race car, I'd definitely bypass it.

It's for the racecar. I was afraid to remove it because I had no idea what it did. Hell, I only knew what it was called after finding the connector in my wiring diagrams! Since I'm thinning the harness, I will bypass it.
