Is the 109 relay that plugs into the front of the fuse box the n109 as shown on some wiring diagrams?
And does it cut the fuel when you turn the engine off?

I have used an AFN engine and loom from a Seat Alhambra and it had a seperate cut off relay labelled "405". A crash relay I think!
I have kept this and am wondering if I should have left it off and connected the black and white wire from ECU pin 53 to the 109 relay instead.

I'm assuming (but could be wrong) that with the ignition on the black and white wire at the diesel pump multiplug "pin 8" should be live? At the moment it isn't.

Hope someone can help!!
