Hi, recently bought a facelift ek4 vti, the previous owner has replaced the engine due to a burnt valve, but when he replaced the engine he has mixed up some of the engine loom plugs to various sensors and it has never ran properly

I currently have the cel on, showing codes 14 (iscv) and 23 (knock sensor)

On checking I have so far found the knock sensor plug (single wire) plugged into the iscv, and something else plugged into the knock sensor

I have since discovered the iscv, knock sensor and the evap solenoid at the inlet share the same plug as well as the inlet temp sensor and I dread to think what else

Is been searching the net for two days on info on what colour wires should be in the plugs for each sensor with absolutely no luck

Could anyone assist or offer a link to a proper obd2b pinout so I can get the car running properly, I can only find info on obd2a wiring :(

Tia and I'd be extremely grateful of any assistance with this
 
Slight update (I'm working on it atm btw)

Since plugging the knock sensor in correctly and disconnecting ecu for a few minutes, after running the car up to temp, the knock sensor code has now gone

Just need to find out which plug has which wiring colour for the idle control valve now as it's the only code remaining
 
Ok scrap that... Figured it out lol no more management light or dodgy idle :)

Thanks anyway people
