About 90% of the wiring is complete, its was a lot easier than I expected, was a bit daunting looking at that nest of wiring at first but I think it turned out nice and took shape quickly.
I used velcro to mount the esc to the computer, that way if it gives me problems, I will just remove the knock sensor and esc completely, nice an easy to remove and no holes to patch up.
I need to weld in the O2 sensor bung yet, I also decided its probably best to buy a new O2 sensor. Since I have dual exhaust, which exhaust should I put the O2 sensor in, the front or back or does it not matter?
