AGG mfa mpg sensor reading 99.9 - wiring diagram required - non golf install

[fufflenarnia]

Hi all,

Ok, you can abuse me as required, but i have transplanted the agg engine out of a very knackered golf into my t3 transporter high top camper.

It is a brilliant engine and pulls the van really well.

I have also grafted the golf dash into the van, so i have the full mfa display, all work, apart from the mgp, which is reading 99.9, so I guess I must have a wire missing.

Can anyone assist, I need to know what signal it is looking for, where from and where to, the diagrams I have used do not show anything for the mpg reading.

Thanks,

Steve.
