I have a HalTech manual (no particular model number given) dated 
sometime in 1989.  The chapters include:
1. Installation
2. Operation
   Main Menu
   Disc Storage
   Functions available in the sub-menu
3. Programming fuel delivery
4. Trouble shooting
5. Compatible ignition systems
6. The components in the fuel line
7. Fuel flow principals
8. Design and injector positioning
9. Principals of EFI
10. How Haltech works

It doesn't have any wiring diagrams, though.
Let me know if anyone wants it.  I can mail
it to you and you can mail it to any one 
else who wants to copy it.
