It was about 18months ago i did it. I connected it into the ignition barrel to a connection that comes live on the click before full ignition, where everything is on the next turn starts car. Meant if you left the key in that position, the pump was pumping without the engine going, where as it normally just primes the pressure then stops till the engine starts.. No big deal as the fuel just goes in a loop i believe in that instance. Once started,the key returns the that position and the pump is always pumping anyway so no difference. Im struggling to remember exact details as too what i did as so long ago. Its quite easy to do if ok working with the electrics.
