2004 Lexus lx470. Replacing main engine wiring harness. The connector on the far right, drivers side, I broke the locking tab. Are you able to buy these locking tabs to put back on connector? Antifreeze had dripped on it from broken t fitting, was compromised. Trying to avoid replacing the whole connector, as it has 10 or so wires in it. Thanks for the help
 
I don't think you can buy just the white locking arm. Input your VIN# at www.partouq.com, see if you can find. Or call a Dealership parts.

But you can replace the wire housing block. Assuming still in production. Look closely at wire housing block, white plastic arm came off. You should find a 5 digit number. Which is suffix. Add to the prefix 90980-(*****suffix)
