Lee P Posted July 1, 2014 Share Posted July 1, 2014 That pump will run on the stock wiring but if your fitting a syvecs take the fuel pump ecu out and put a relay in its place Quote Link to comment Share on other sites More sharing options...
shetlandsupra Posted July 1, 2014 Author Share Posted July 1, 2014 I've got the aem stand alone v2 my mate says run 12 volt through a relay? Quote Link to comment Share on other sites More sharing options...
heckler Posted July 3, 2014 Share Posted July 3, 2014 I had the same setup. used an Output from the ECU to trigger a relay, which in turn ran the fuel pump off the battery. Quote Link to comment Share on other sites More sharing options...
