Yamaha S90XS - Broken Inlet Assembly

I successfully removed the part and found a replacement for sale here, but I can’t get the three spade connectors to come loose from the part. Is there a trick to it, or are the soldered?

Do the spade connectors have a small nipple to keep it from coming loose?

These usually need to be pressed to allow the spade to release.

Otherwise, use a terminal screwdriver to release the grip on the spade.

Not spade lugs - soldered on - use knife to cut heatshrink and unsolder.
