Hey guys I am curious about a 1991 talon TSI mpi relay, is pin 8 on the relay supposed to be ignition power or grounded? I have looked on the forum and seen people saying both answers I talked to a good buddy of mine who knows electrical a bit better then I do and he says ignition power but I'd like to be sure before I go and wire it that way. Reason I am asking is my car has a plug and play aem ecu and my MPI relay is not doing anything o i have no spark or anything associated with it. When I go back to a stock ecu the car runs just fine but rich as the car has large injectors which is why I'm trying to put a standalone in it. Please do not turn this into get dsmlink I have a better ecu but it requires me to completely build a harness from scratch and all I want to do is get the car running ATM thanks guys.
