I noticed that the wiring connector to the Mass Air Flow sensor on the air intake had all its locking tabs broken. It is just plugged in with no locking tabs. Vehicle is a 2008 RX350. This raises some questions:

Can this connector be bought separately from Lexus? If yes, what is the part number.
Is it easy to remove the wiring ends and install it on the new connector? Is there a "how to" on it.

 

Happened to me and searched, found out people were using tie wrap to secure it, I did the same, no issues. Every now and then I check is connection is still secure.
