How do I read codes from a 9A

[JohnBoy 0]

Hi,

 

I have a 9A from a passat GT transplanted into a mk2 golf.

 

I've had some problems getting it up and running right but with a new temp sensor and a few other bits done but I've still got a really high CO, 6%.

 

Now I dont want to go swapping out parts at random, although we do suspect the lambda.

 

I know the 9A can be diagnosed somehow, and I've seen guides that connect leds to the diagnostic port.

 

but I dont have a diagnostic port.

 

I only have the engine loom back to the fusebox.

 

how/where would I go about either fitting a diagnostic port, or tapping into the loom and flashing the codes from there?

I think your best bet would be to speak to someone with a 9A Corrado, for instance, at a show or locally to you, and see if you can trace the 2+2 connector wiring from under the gearstick back.
