On the trim pump blue,sky, is up, green, grass, is down. So on the selonoid you have a live feed and up or down on the big nuts. Then a earth feed and live from the switch on the small actuators. Hope that makes sence, oh and the pump body needs an earth.

Many thanks but I have 3 wires coming out of the pump, is the black wire the earth and will I still have to earth the pump body?

Most of the early stuff can be covered in the manual I posted.
Matt put it in the Gallery link to it from XR2 Help thread in theis section cant post it as through a proxy.

It would be good to have a look at a diagram to see if I've done it correctly, although it was pretty simple once it had been explained.
I'm just not sure about earthing the pump body as it's working perfectly without it. Although I can't see that it would do any harm.
Thanks folks

Mike diagram for the 2.5 EFI but should be the same as yours

Its the pump motor that needs a -VE not the body of the pump housing. think that was a x purpose chat before

Many thanks BluFin, the diagram confirms that I wired it up correctly.
Thanks again
