Changed the engine on my 2001 endura de diesel.

Changed the engine on my 2001 endura de diesel 55 n/a van for same type engine I have bypassed immobilizer by taking live from back of ignition barrel to starter. Stop solenoid has two wires on it if I connect this to a live when dash lights and which wire? Should this start the engine, and do I. Dont I, unplug the multi plug connector to the injector pump, or do I change the stop solenoid for a single wire type, or do I need to change the injector pump because the ecu and pump wont match really testing my knowledge. Would really appreciate your help !
