Hello, I purchased a replacement fuel level sending unit for my 79 620 and I'm not sure what the proper way to connect the harness from the old one is. The new unit has two posts for the wires, but I'm not sure what type connectors to use on them? This is a little different than the original which has one post that doesn't appear to be removable and the other wire is connected directly to the top of the unit (no post).

Thanks!
