Early 1 or 3 wire O2 Sensor

[338WIN]

Finally put my 83 w/auto trans back together. Lab pup ate the O2 wire when the exhaust was laying on the ground. Don't know what it tasted like! It was a one wire, but I noticed that the three wire connectors are in the harness.
Any reason to use one over the other? Looks to me like the three wire should last twice as long?
(My one wire connector is broken at the mount and I'll need to use a universal connector if that is a factor.)
Thanks, glad to be driven the p-car again. I had it sitting on blocks for way too long.

Two white wires are for heating the California-spec heated O2 sensor. If you go with the one black wire you should be fine. Don't solder the connection, it needs to be open to the air, I've read. Did this with my Cal-spec car and it's fine.
