Not yet... Here's the D50 (Ram 50) Truck section. Couldn't get the full PDF to upload so broke it into two parts in case size (or corruption) was the upload issue.

1987-88 Mikuni Vacuum & Electical Fuel Control Systems_Part 1.pdf
1987-88 Mikuni Vacuum & Electrical Fuel Control Systems_Part 2.pdf

I skipped pages that were duplicate illustrations or ruled for notes only. Has very good illustrations, explanation of component functions plus some diagnostic tests - easier to follow and more thorough than the FSM. It's not perfect but is the best I've found.
