Hello lads need a little bit of help I have my fcd wired into my map sensor in the engine bay but I'd like to wire it in the car to the ecu . Dose anyone have a link to a diagram or dose anyone now what wires I need to connect them to in the ecu loom ?
Any sort of help would be appreciated .

Do you mean the loom on the ECU?

It must have a ground somewhere otherwise it wouldnt work properly.

Do a diagnostics check and find out what the fault code is. You can do that using this:

You will need to source the earth on your wiring loom and ground the ECU. There must be one somewhere. If there isnt then that is probably your problem.
Check there is an earth direct from the battery to the bodywork as well.

Check the pin out diagram for another earth and wire the FCD into one of them.
