    Attached is information on converting the TBI computer in your pickup to MPFI (basically same a TPI). With some careful planning you can reuse the TBI harness with some minor modifications. A few wires will need wiring length changes by adding or subtracting wire, then adding 8 individual injectors (4 injectors per bank instead of 1 injector per bank).
