i bought a cossie and dropped another engine in but the boy i bought it off for some reason took the abs loom out, im not to bothered about the abs in all fairness but i was told i need to power the vacum pump on the servo to get the pressure up. how would i do this? there is alot of places to plug in plugs and ive got a live and a earth comeing from just bellow the pressure tank. so is it just a matter of putting the live to ignition live?

this is the only thing i need to do now to start driving it everyhing else has been sorted at last lol
