My current actuator only has two wires this one appears to have more 3-4?
David W on Mar 2, 2016
BEST ANSWER: The drivers door actuator that I replaced has 5 wires in as I believe 3 of them go to the other doors? I'm not sure why you would only have 2. The replacement I purchased from 1A Auto has worked well since I've purchased it.
