Thanks! Yeah, you have to homebrew a wiring harness with a potentiometer and a relay in addition to powering it from the up fitter switch. Finding info online from people who have done it to the 6.2 trucks is almost nonexistent. No one could say whether you need the relay (you do) shown in the Ford BBAS wiring diagram for the SEIC. Voltage has to be applied in sequence for it to work. I’m happy with it. The potentiometer is discreetly tucked away into the cubby where the passenger airbag switch would be so there are no signs of any mods. All the wiring was put into loom and taped up so it looks factory. Appreciate it! Everyone says, the first time you hold her you can’t describe the feeling.....I always thought that was BS. I can tell you for a fact it’s not.
