I thought the knock sensor wiring came out around the back of the engine.

Well I reset the computer yesterday and it went 25 miles without the code, and then mile 27 came up and the SES light popped back on. The knock sensor code came on about 300 miles after the clutch was done, so I don't think I pinched any wires. The code is for low/insufficient voltage, I'll go and get the code in a few minutes and post up. I've thrown knock sensor codes once or twice in the past so maybe the sensor just finally went.
Edit: Code is a PO327 for low input for knock sensor 1.
