Relocation Of Windscrrem Wash Tank To Boot Wiring Help

Hey guys. I just relocated my windscreen wash tank to the boot using this kit

 

http://www.ebay.co.uk/itm/281845287554?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

 

Its all plumbed up ready to roll with the wiring to were the original plug is located.

 

But does anyone know how to wire them?

 

There is 3 wires on the original, 2 wires on the new kit.

 

When we used a amp meter to check the voltage of which wire does what it seems like there is a constant 12v going to it.

 

Does the OEM pump have a built in relay?

 

Thanks

Paul

I just wired the pump by making the wires longer from the engine compartment. There are 3 wires, because one is ground, one is 12v for front windscreen and the last is for 12v for rear windscreen. The aftermarket wash tank you have linked to, does not have a pump for both front and rear.
