Yes - and I think the GE relays all now come with that connector, too.

I have one of the GEs; the only markings on the connector are "AMP" and "85". It might be possible to find a mate in an electronics distributor catalog like Mouser or DigiKey. But it'sa n insulation-displacement connector, which means an expensive installation tool. Probably better to cut it off as you say, and maybe crimp on a few more inches of wire.
