Thanks.

I know exactly where you mean. It's where Alldata shows the RCL unit. But it's not there. What is there is the ATA (alarm) module complete with its 33 pin connector (RCL has 18) and correct PN 140 820 6626. I removed it to get a good look behind the brace and filler tube. Nothing.

I also removed the liner on the front trunk bulkhead and looked around. Again, nothing.

Here's the other diagram from Alldata.
