ALDL pinouts

[b4black]

Where can I find the pinouts for the ALDL connecter? I want to hook up a light to monitor TCC lockup. I would also like to know what the rest are. ( I can't find it in my service manual )

Thanks

Looking at it from the front (assuming a TR ... other vehicles vary slightly):

1 2 3 4 5 6
X X X X X X
X X X X X X

Top row:

1 TCC (Goes to ground when "on")
2 Serial data
3
4
5 DIAG control (open = NORM, Short = BACKUP, 3k = DIAG, 10K = ALDL)
6 Ground

Does there happen to be a 12 V power source in the ALDL as well?

Nope... not normally.
