This valve necessitates 4 ECU outputs to get pushed, so I had to reallocate stepper outputs STEP1-4 and change the harness. STEP1-4 are actually linked to a plug on the drivers side in the harness, in close proximity to in which the idle Regulate valve is going to be mounted. https://4ageengineforsale03222.educationalimpactblog.com/51187598/not-known-facts-about-4age-20v-turbo-engine-for-sale
