HUH?

Rereading the original post says that it is a 97. A 97 truck had Vortec injection with a computer, not a TBI. The distributor is plastic with a flat, low profile cap. It has the cam position sensor integal to the distributor body.

The computer is black and mounts on the driver side fenderwell in a snap off bracket.

I have five 96-97 units here right now, we are in the process of putting one in a Toyota Landcruiser. That's why I have the shop manuals, the Snap On tester, etc.

What am I missing?
