I'll try. Those things are about impossible to look up with the catalog I have. I do need to know what you are working on though. It looks like an SW20 but I want to be sure.
EDIT: It looks like it's not the connector you need, but the rubber boot that seals it to the harness. Toyota does not supply that by itself. Here's what I used to basically build a new one:
Harbor Freight Tools - Quality Tools at the Lowest Prices
Home
Design Engineering, Inc. - Fire Tape
This stuff is great. You can basically wrap an entire wire harness in it if need be. It has no adhesive and never gets sticky, but bonds to itself when it is stretched. Fun stuff.
