Once the ECU is unlocked, these need very few wires to make them actually run - basically the engine loom is pretty self contained and only requires the ignition switched +ve to power up the ECU, which in turn itself powers the double brown relay.
The only other two things required for it to start is the lift pump - which also goes back on the big plug on chassis leg, I've seen Ph2s with and without the wiring there for a lift pump on the fuel sender plug - so that may need manually adding.
Then you need the starter solenoid wire that will engage and turn the starter. Then the engine will actually start and run by itself - no other wires are actually needed for it to run - long as you keep the power signal to the ECU and the double relay stays live, the engine will run.
Speedo drive is on the same wires back to the dash, but uses a different signal in XUD, so you need to swap the dashboard for the speedo to work.
The rest is ancillary stuff that will simply need connecting - it may be on different pins on the plug, but it's no different to the stuff on any engine - it's all compatible, stuff like oil pressure light switch, reverse light switch, battery light (which is required to get the alternator to self excite) etc etc.
