Default Help diagnosing solid red LED on OBDC

Still getting solid reds on several A & B sockets on my '93 850. When plug in the fly lead, the LED comes on and stays on. I have a couple of codes on other sockets, but can't clear anything, just seems locked up. How can I trace to find out where something isn't working right.

Is there a connector between the A & B probe sockets and the computer box, other than the 2 prong plug under the A & B boxes? I wonder if I disturbed something when I worked on the timing belt and t-stat. What's in there that I could have knocked loose?
Thanks.
