.
I am new to this diagnostic code caper and I'm keen to learn about it and use it tuning my NF Fairlane.
I have the Ford factory manual and a reasonable mechanical ability.

I want to track down an OBD1 code reader.
I've searched the forum and can't find any info on where to buy them.
(There is supposed to be such info, so i'm told, in here somewhere. Buggered if i can find it!)

Can anyone point me in the right direction please?

This is what the connection point looks like .....


Cheers,
Greg
