merckx Posted August 18, 2004 Share Posted August 18, 2004 I've got a 1997 VVTI TT, I was just going to wire in the fuel cut defender but I'm not 100% sure . Here's the wiring diagram: VVTI The colour of the wires coming from my ECU don't correspond with the ones in the diagram. The MAP wire is yellow/black (blue in diagram) 12V Power is red/black (red in diagram) 0V Ground is brown (black in diagram) The layout of the connectors is the same as the diagram. Is this normal that the wires are different colours, just want to make sure before I start cutting. Speedy response much appreciated.

SimonB Posted August 18, 2004 Share Posted August 18, 2004 The colours on that diagram refer to the wires on the FCD, not the ECU I think. I've just been installing my Emanage, and I know that the MAP wire is definitely yellow/black on my facelift. Not sure about the others but I'm sure Petes diagram is correct, just make sure you're looking at it the right way round and you should be fine.

colsoop Posted August 18, 2004 Share Posted August 18, 2004 have a look here at the instructions and it tells you the wire colours http://www.thor-racing.co.uk/TRL/vfcc_mkiv.html Quote Link to comment Share on other sites More sharing options...

Thanks Simon, I think you must be right, the layout of the connectors on the ECU do match the diagram. Just a bit reluctant to cut them when not 100%.

Just a bit reluctant to cut them when not 100%. If you aren't sure just unplug the relevant ecu plug and the MAP sensor plug and check for continuity. On EVERY VVti I have fitted an FCD to, and i have done a lot now, the sensor wire has been yellow and black. Blue from FCD to the ECU side of the cut yellow / black wire, green from FCD to the map sensor side of the cut wire. Quote Link to comment Share on other sites More sharing options...

Had a quick look at the MAP sensor and it does have a yellow/black wire along with 2 others. Thanks Quote Link to comment Share on other sites More sharing options...
