IMHO...the easiest way would be to purchase a 94/95 Cobra PCM (box code J4J1). I know the Ford dealer around here is usually $150. I normally change this with the chip but it is plug-n-play and works good...you will have to upgrade the injectors to 24# and a new MAF. However eventually you'll want to change this anyhow.
