Default ECU loom - can anyone tell me why this won't work?

Hi everyone, I'm thinking of building a one off special using a classic chassis, a hand laid body and a modern alloy motor for added lightness.

I'm looking at the Rover 25/45 or Ford Puma for the engine which will be coupled to an RX8 gearbox http://www.p9cyoplates.co.uk/products It also looks like it's cheaper to buy a complete car than just a motor, so I'll have the whole thing running before I start, so at least I'll know for sure it worked before I started messing with it.

I'm trying to find information about wiring up the ECU's on t'internet, but all I keep coming across is people spending £2-3k on throttle bodies, bike carbs and aftermarket ignition systems only to find they have to pay a specialist another grand to get it running right.

So, I'm thinking, why not reuse the complete loom from the donor car? Why couldn't I just strip out the entire loom, complete with battery, fuse boxes, ECU's, ignition barrel and all, thin out/blank off the redundant circuits and plop the whole thing into my chassis so the engine plugs and plays exactly as it did in the donor?

Anyone out there with any experience or knowledge of doing this?

All help gratefully received.
