For any future readers, the pigtail
@reogem linked on Amazon, worked perfectly for me. I needed to replace the little pigtail on one of my 660 Grizzlys starter solenoid/relay.
For the sake of saying it, the 3 wires are all the same gauge, don't be alarmed. I had to move the upper LH connector down to the lower LH hole, but that was just a simple flathead under the connector and out it came.
I went ahead and ordered a spare for the other bike, didn't make sense to pay for shipping when I'd just as well get an extra part instead, and hit their free shipping minimum
edit- apparently I can't paste the url, must not have enough posts. Anyway, it is the one
@reogem linked in his post.
