I've been installing a 12 way boost pot to my p8 ecu. The instructions I got said for pectel connect the aux input to pin 9. My wasted spark loom already has pin 9 already fitted toto the connector, so I thought that would be. But it also says if running Als/wasted spark connect it to pin 26. Thing is my wasted spark runs of pin 26 and I run Als. So I'm a bit confused?
