    I've heard it can be a bear. Read up well. Get some of the '91 service manuals and study those diagrams. Getting all of the wiring from the donor is a must.

    If you didn't get the harness, computer, sensors, from the donor truck you will need them all. You will also need a fuel pump, Add a fuel return line back to the tank and a distributor made for the TBI system. The TBI you have will not work with out all these.
    You can get a wireing harness from: Painless performance they cost around 300 bucks.
    You can also get a lot of stuff you need from these guys:turbocity.com
    It would be best if you can find a donor truck at a junkyard or somewhere to get the stuff you need from. Buying the parts from aftermarket suppliers can get quite expensive.
