i have neither yet, so will be a K6. unless i change my mind before purchase but Emerald does look like a good product for the money. Only other option im considering is DTA as im only an hour away from the guy who makes them, was recommended by a tuner i visited. Wayne from chip wizards.

dont know of any mk4 escort available with aircon. i will check haynes manual but sometimes the diagrams make things more confusing.

thought someone may have come accross this on their car where it was plugged into something, as you say its a big power cable so wouldnt be there for no reason. unless for heated windscreen option? My efi 90 spec xr3i has heated windscreen but dont fancy taking the dash out just to check lol.

thanks anyway!
