Your part numbers look good, but both 206430-1 and 211102-1 are the same thing, but the last one has threaded inserts, so you could use a machine screw without a nut. If you are planning on using a nut and bolt, use the first number for the panel mount on the battery box. Slight difference, not a show stopper either way.
For pins, you could use 66099-4, 66099-3, or 66099-1. Those are all either selective gold or full gold plated which helps it resist oxidization vs the bright tin contacts.
For sockets, 66101-3 or 66101-4 are both good. They are all crimp pins and sockets, but like I said, its not a problem to solder to them and still stuff them into the housing anyway
They have a high current contact which is rated at 25A instead of 13A, (rating for a single connection, you cant actually do a whole connector with each pole passing 13 or 25A )
pins : 1-66361-4 sockets: 1-66360-4
They have ones meant for soldering also, unsure if those would be as available as the crimp ones or not, but the part numbers are 66180-1 for pins, 66181-1 for solder sockets.
Your part number for the backshell looks like the right thing, even though its not in the catalog ( :ironic: )
1-206062-4 is what they have listed, and may give different results on various stock house websites.
For those that want to play around. 1546347-2 is a right angle backshell that can be used. 207490-1 is a cable grip which screws onto the connector, and 207489-1 is a cable boot which goes over the cable grip to make a strain relieved and nicer looking backshell.
Though none of these are water proof or water resistant as they come from the factory, so if you want to do so, some neutral cure RTV silicone (not acid cure, that will corrode the contacts!) may be in order. "Sensor safe" RTV from the auto parts shop would work.
