White plug on ecu loom

I have put my ecu harness in the car and bolted the plug to the ecu,
just up the loom inside the car between the blue ecu plug and the green relay theres a thin white plug.
anyone know what it plugs into?

lets have a piccy stu

I will get one up later, but bob said its something to do with the priming of the fuel pump.

I thought that was Green, its actually a ign on relay

There is a green relay right by the white plug.

i will get a piccy now.

Does it go to the back of the 3 gauges?

no that one goes where i said stu behind the centre consul on left hand side, its normally clipped into a bracket, youll have to get your mitts up there to find the end....it then goes into the rear loom and if you unplug it the pump wont prime.

Thanks Bob. i will sort it out next week hopefully lol
