ok im just back from the garage. Theres 2 main parts of the loom for plugs - the part that has the plugs for the metering head, amal valve, TPS, charge carrier etc. I got all that sorted out fine,

Its the part for the head im having a bit trouble with. Theres 2 yellow plugs, a black, a green and a blue. One yellow goes into fuel rail, green into right hand side plenum, and other yellow (I think) goes into underneath the plunum next to the fuel line, Ive got the blue and a black left.

Can anyone think what these are for?

Forgot to mention, ive also got another tiny plug that looks round and just clips onto something?? any ideas? ill try and get a pic.

thanks for any input!

Jamie
