Anyone know what pin 23 does on the ecu connector? (White wire linked to ecu relay pin 86a). At the moment I`ve got it spliced into the ecu live feed, as per a wiring diagram from the net. Just thinking it may need to be live with the ignition off to keep the ecu memory intact or is this not necessary? Does it need to be connected at all? (one diagram says the possition isn`t used?). Cheers
