Do a bit of a search as most of this has been covered before. I did have a quick look but could not find it, and I put a lot of the stuff there. You are right the diagrams in the gallery are for gen3. This should not be a real problem as the are only several main defferences.
1. The pins outs - the gen 3 had different number of pins on the plugs and therefore different pin outs. I have posted the gen2 pin outs in the gallery. Also note that I have posted the pinouts for the other two plugs in the loom located near the computer. One is for the dash and the other for the rest of the car electonics. Again look in the gallery
2. The Gen 3 does not use an ignition ballast resister. If you have the original loom this will not be a problem as its location will be obvious - its the rectagular box near the coil and ignitor. If you still have problems I can scan that page of the manual.
I have never seen a full wiring diagram for a gen 1/2, just the bits spread through my engine manual.
IF you are still having problems give me a ring on 0413190752.
