What RABS computer can I use?

I pulled a dash wiring harness from a 93 and it also has the RABS computer. How do I identify this computer to know if I can use it on my truck? Will any RABS work?

According to my books, '93 was change to RABSII module numbers begin with F3TF-2CO18 or F3UF-2CO18 other module numbers are RABSI. Doesn't appear that they will interchange.

No problem is so great that it can't be overcome by brute force and ignorance.

I've got to think this is RABS, I also pulled the RABS valve from the same truck and it looks exactly like mine.

Here is the unit I have - http://i.imgur.com/MkWlM0M.jpeg

I guess what confuses me is where it says single rear wheel only. And I did visually verify the RABS valve on my truck is the same as what I pulled from the same truck I got the harness from

That seems to be a RABSII module, the single wheel only means not for a dually. That is the same as mine ('93 RABSII).

That makes more sense

You happen to have a wiring diagram for RABSI and RABSII that lists what each pin is for? I'd like to understand the differences
