Should have been clearer sorry. Those wire colours were for the pedal. I was just thinking it might be possible to trace them to a connector is the engine bay that may have gotten wet. Took a bit of a look at mine, but couldn't really see anything obvious to me.
Going by what SV6.07 is saying, that all fits with what you're seeing and what I'm thinking. Sounds like the dodgy connector is in those two plugs, and this looks like simply putting a new connector in for those wires. But instead of replacing the whole plug they're taking the offending wires out of it and giving them a new connector. For now, I'd give those two connectors in the pics a good clean since you've got some cleaner on hand. It may work, but if it does it is guess work as to how long that would last. Might have to do the bypass anyway. Just a crappy fix in my opinion. Perfectly sound in working, just would be better if the original plug could be replaced in its entirety and look exactly stock.
Maybe I'm missing something, but if cleaning those connectors in SV6.07's info doesn't work, surely it'd be much cheaper to do this yourself. $20 at jaycar gets you a 6 wire waterproof connector, $5 for standard one and solder it up yourself (if you can). You're reading the code and can clear it yourself, so save $400+. (I take it that its still the same one, not p2176 now)
