The first time, I wired it up based on the colours and connections indiciated in the manual by shortening the loom, and things were very confused. After an enormous amount of faffing i got the ECU to intermittantly function.
The second time I got exactly the same results but with no functionality by wiring it directly from the wiring diagram. The reality is that there are quite a few additional connections, earths, shared VRef feeds etc, that are not indicated on the diagram, as well as a few circuits for the ECU that are simply missing, immobilizer for example.
What I did in the end was wire up ll the sensors, get the ecu to report fault codes, and work as expected, then on at a time removed things that were not connected up to anything. This left me with a minimal loom, including relays, fuses etc. I then followed each wire to the fuse box, and cut it at the fuse box end. The cut wire was then re-routed, and extended/shortened as required to the engine feed wires.
Each time I did this, I turned everything on and made sure that things were still functioning, this made it easy to find any problems if I introduced any.
The result is that I now have a handful of wires coming out of the bulkhead to power and control the engine, these are tidily spliced into the engine loom which also goes through the bulkhead to the ECU.
The end result was that I could start the car, it fired up first time, with no fiddling which was just what I'd hoped for. I let it tick over for a while checking for bad sounds, leaks and any problems.
Things got pretty smokey as the heat wrap burned off all its chemicals, but settled down nicely, the side pod gets pretty hot, above the manifold where there is no heat shielding, but stays pretty cool everywhere else which I hope will be fine. I think I will make another hole in the rear of the pod to let the air out when driving though.
Hans came over so we fired it up again and had some fun with the loud pedal.
Since then I've taken it for a quick spin around the garage car park, this is going to be great when its on the road.
