S1 5L into older project. ECU/BEM/key requirements???

[mikecool84]

Hi guys, sorry to have yet another ECU/BEM question but I dont think it's been covered, if it has I am sorry and please send me the link.

I have a 98 S1 Fairmont v8 and auto to go into a 1950's International pickup.
I have the engine, auto, ECU and short loom (eng to ECU)

Can I get this going with what I have?, if not what do I need?
Bear in mind the end use, I do not want to use the AU keys or instruments but I do have to use AU injection and ECU.

Thanks in advance.

Mike.
