hi, just put my engine back in today on my s2, and while wiring it back up ive forgotton where a small yellow multiplug goes on to behind the inlet manifold, ive got all the rest on just cant see where the yellow one goes on to,

any help thanks

 

Im pretty sure its the one a bit futher down under the cold start one(Blue) its a bugger to get too and see but its there

 

i got a bit stuck with this problem, untill i read the haynes manual.

 

Its the CTS plug and its literally mounted vertically underneath the plenum runners of number 1 and 2 cylinders.

 

thanks for your help
