850 keyless entry autolocking issue

Hey all

In an effort to not bump a super old thread I'm starting this one. I've followed the awesome write-up here to put keyless in my 760:

It's working now, but I occasionally have it relock within about a minute of me unlocking it. I worry I'll end up locking my keys in at some point. I assume it's looking for a signal that one of the doors gas opened to disable the feature. Anyone worked that through or had this issue?

I believe that's normal behavior for an 850.

I number of Volvo and Toyota products I've driven will relock themselves after a few minutes of inactivity.

The odd thing is it doesn't do it every time, but that could mean it's normal behavior, but that logic in my relay is getting old and inconsistent.

Either way, I've got the diagrams now and plan to dig into this; but feel free to let me know if anyone already knows which pin needs a signal from the door switch to deactivate it!
