Mystery plug

Recommended Posts

This seems like a plug for an aftermarket engine heater or something... Someone had some spliced 3 prong outlet into it from the last car that attached to nothing, maybe something Gerry rigged off the battery?


08 LGT Spec B engine.

That’s a block heater. You would typically plug it into an extension cord at your house. We used to use them in WY when it would be -20 overnight.


That looks factory with the clips on the plug wire.
