aps? any more info on this? or do you mean pulse air system? if so thats all good at the minute, and if it was that i'd still have another plug hanging around

i can't seem to find a component that's not plugged in anywhere, and after looking at the wiring on some of the escorts in the breakers yard the suppressor is now correct,
but according to the wiring diagram for the 1.3 hcs, which was originally in the car, it goes to the suppressor, however the 1.3 looms have been removed and 1.8 looms installed, but if it is then why is it in the 1.8 loom if thats the black wire plug?

major mind f*ck now
