short version - IT RUNS!!!!!!! Long version below 
Ahhh, wiring.
Stay with me on this - this is the bit that I was keen for everyone to appreciate about EFI swaps, but I did manage to stuff it up a bit so I'll give you all the details so that someone might learn from my mistakes not their own.
And a massive :armsup: to Mugginsmoo, Cj and Mightmouse for their help.
(oh, fuel filler is done and went well)
As pretty much any sierra service job is heaps easier with the front clip off, I have tried to make this as simple as possible.
So to the wiring. I got a bit obsessed with neatness for then engine bay, so as the Baleno loom runs straight into the car behind the block, I have stripped all the Sierra carby wiring out of the sierra loom. This has massively reduced the bulk of the loom on the firewall and inner guards. so I have built a power board containing all the powerups for the computer, fused, and the relays for fuel pump and main power, along with the headlight relays.
I have also relocated the headlight loom Michael has to the firewall on the inside of the car to clean up the engine bay - there's no relays etc in the bay at all now.
Neither of these were my problem...
We ran the battery cables, filled everything with oil etc, and hit the key... and that's where the pain started
EFI Suzukis only actually have 2 relays that run the injection side of things, a main power relay that powers everything, and a fuel pump relay. anything else will normally be "optional" like fan control etc. We had power to the main relay, but the fuel pump wasn't firing up at all. We also had no check engine light. Bad.
I got a bit annoyed by this, but we checked the pump (working) checked we had power to everything ( sort of did - I had put a pre blown fuse in the fuse box
) but still no go. I started to think about all sorts of options, and rang Cj to see if he could confirm whether this car had an immobiliser or not. It didn't look like it.
I spoke to Mugginsmoo, and he hooked me up to a source for a Baleno factory service manual site. With this downloaded, (128Mb, thank God for ADSL in the bush!) we consulted the computer pin out chart and I picked up that I had incorrectly wired the power to the computer.
This was then rectified and we had a fuel pump running - Yay! but we didn't seem to be getting a check engine light, and it wasn't starting either (cranking, but not catching)
I wired in a new check engine light to sit next to the computer, and tried again - and we got a flash code on the light. Checking the FSM, it confirmed that the code we had was for "no trouble" - Ooookaaaay then.. BUT - we shouldn't have had a flash code at all. This meant that the diagnostic link was grounded ( the diag. link is like the scan tool the dealers use but more crude - it makes the check engine light flash a code that tells you what's wrong. I fitted one to a carby car once, but the code flashed just said "running like crap"
Oooo I crack me up with my nerd jokes)
Becuase when I stripped the Baleno loom, I didn't use a wiring diagram to help me, I made a couple of booboos. ONe was mentioned above about the power up, the other was that I wired the wrong violet/yellow wire to the speed sensor - the diag link. This was why we got the flash code when we shouldn't have.So we clipped that wire, and tried again. it cranked, popped once... and smoke fairly billowed from the ECU.
We pulled the ECU, found a burnt transistor, and pretty much got depressed. Michael left for the evening as it was 11.00pm by this stage.
I sent out a couple of frustrated PM's. but didn't want to give up, so I did some thinking and had a look at the ECU board. It looked like I'd only shorted the check engine light, and that there might have been no other effects. Due to my lashed up check engine light, it was certainly possible i'd shorted it, but knowing that computers are enormously hard to kill, I thought I try to start the engine anyway, safe in the knowledge that before the *ahem* smoky incident, we had an "all clear" from the check engine light.
I did some cranking, and at about midnight, it fired into life, on 2 cylinders - 2 and 3. Hmmm. I swapped the coil packs over, and now it fired on 1 and 4. so thats just a dodgy coil pack.
now to the ECU. I rang Dad this morning and we had a chat about it, and he thought it was possible that it was an isolated failure, and a generic component. (he is an industrial electronics engineer) I took it down to him, he had a look, replaced the component with a generic one, and we now had a working check engine light! :armsup:
I have wired a switch permanently across the diag link switch so if the check engine light comes on, Michael can just throw the switch and it will tell him which component has gone down/faulty.
Oh and the Baleno tach works too. It needs a little "tune" as its energised base point is a bit high (like about 700 rpm ATM) so it's reading too high. I'll just do that by manually adjusting the needle rest position.
Basically, all the wiring is now complete. I don't have a photo of the completed job - I'll get one as we're putting the dash back together, which will be getting a coat of black paint.
Steve.
