Aquamist pump and a water tank pump in the boot
 

Hi guys this is my first post,

I'm pulling my hair out and I can't get my head around it, I need some help please.

I have install an aqua mist system with a manifold pressure switch, the tank is in the boot of car.

I would like to know how to wire up the small pump in the water tank to switch on at the same time as the main aquamist pump switches on, I have ran positive and negative from the boot to the engine bay then spliced into the wires red and black on the the harness loom for the aquamist pump. When I switch the ignition on the pump in the tank continuously operates!

I've missed something the pump should only switch on when the manifold pressure switch reaches the desired boost level. Can someone point me in the right direction what I've done wrong please?

Aquamist System 1 the racing version 806-052

Thanks Richard, what is a pulse extender do you have a picture of the pulse extender? Do you sell this part and is the part in stock?
I don't believe I have it with my kit!
