I did a search, and google search and came up with nothing. I forget how many, Like 4 or 6 wires connect to via plug.
I should have taken a pic while it was on the engine but did not think of it. What ever it is its factory.

It's a relay,doesn't appear factory to me I've never seen a relay sheet material screwed to a SBC valve cover factory. Since it is a relay,no telling what it controlled,horn,heater,blower,wipers,starter,ejector seat,etc.

crazy, I did a google search and only one other person ask this question and no one knew either. Interesting ;)

Come to think of it, My truck is a camper special. Im going to trace those wires tomorrow.
I plan on swapping valve covers so want to make sure if I need it or not. :Big Laugh:

Was It a twin battery truck? Some of the those used a relay to isolate the two batteries when the engine wasn't running.

Those aren't OEM valve covers anyway, they came on factory replacement motors like the Target Master. It looks like that's the drivers side cover, not sure what'd be for??

I have a motor from a 84 sitting in my shop floor with that same thing on the valve cover. Unfortunately none of the wiring is still in place so no idea what was hooked to it.

I never remember what the dang thing is. But, I do always remember that @Craig 85 knows what that relay is for. Lol.

Some type of speed switch or something. It's factory, but since the engine was a replacement, it's not attached like the factory did it.
