Accel also sells the Variable Injection Controller (i.e. VIC). This box
has 8 injector drivers, and should plug right into the DFI harness (I
assume?). When I toasted a chip inside the DFI box, I opened it up, and
spent several evenings drawing schematics on scrap paper. You should be
able to see the four injector drivers screwed to a "heatsink" (which in
turn is screwed to the case). I didn't bother drawing out the injector
driver section of the board, since it wasn't the chip I fried. I replaced
the 70 cent chip, and the box works again :)

>   I'm new to the list. My project is a 73 elcamino with a destroked 400 small block (377).I'm going to use a D1 ATI supercharger with an intercooler and EFI.
>   At this point a have purchased a pair of used accel 74022A ECM's. My plan is to somehow combine these two so a can have eight peak/hold drivers. I don't feel good about using 8 50 lb high impedance injectors with the simultaneous double fire that this unit is set up for. The on time at idle would be far less than 1.5 ms.
