Here's those pics - better late than never!
I'm well aware of the date this topic was posted guys, apologies for the resurrection; but I think I've got the same problem on my 03 LE. Been scouring the web for a diagram, relevant instructional or even a pic of the new part as I'd like to know how serious this is - zero luck - this thread is the only lead so far.
Looked at another Corolla and there is a cable from the top of that rubber bracket to somewhere behind the wheel (^mine's sheared off^). Took my wheel off and I can't find the other end. The configuration is different on the driver's side tho - there are small diameter metal hoses/lines running down the wheel well and there's a similar elbow-type bracket that protects them; but no cable.
I'm thinking this mystery-passenger-side-only cable might be seat belt related as there's an anchor point around there on the interior side of the wheel well underneath the trim. I don't want to dismantle my back seat to be sure tho (not yet, anyway).
Any help with identifying this part is greatly appreciated in advance. Sending a link to the FSM via PM would be even better!
Thank you for reading.
