disabling autocheck bulb-out indicator

[Steve Barber]

I'll be doing the relay thing to the Audi and want to make sure I
disable the autocheck indicator at the same time.

I dug through the archives and found references to removing the
output from the bulb-out circuit from the autocheck connector,
but no details.  Can anyone be more specific about which wire,
for those of us who are Bentley-less?

Or alternatively:
Where is the bulb-check circuit located? (This is an '85 5000.)

Thanks,
Steve
