Wire Pinout and Colors Pin A: Brown/White - 5V Reference Signal Pin B: Black/White - Sensor Ground Pin C: Dark Blue - EGR Position Signal Pin D: Pink/Black - 12V Ignition Power Pin E: White (or varies) - Ground Control for EGR Solenoid [1, 2] Understanding the Wires 5V Reference: A low-power current sent by the Powertrain Control Module (PCM - the car's computer) to the EGR. Position Signal: Tells the PCM exactly how far open or closed the valve is. Ground Control: The PCM completes the circuit to actually open and close the EGR valve using this wire. [1, 2, 3, 4] This is what AI is telling me, in absence of access to a complete service manual for the truck. So there are two grounds and I think I determined one of them is bad. I need to run through the test sequence again to validate what I think might be a bad ground. I'll be honest, electrical isn't my strong suit, but I'm learning. -
That remote-start behavior is worth separating from the AFM/DFM side. A lot of plug-in modules depend on when the vehicle wakes up the OBD-II network and when the module initializes. Remote start can change that timing compared with a normal key/button start. I would not treat unplug/replug every time as normal daily use, though. If the main goal is Auto Start/Stop only, the dash button may be less annoying. If the goal is AFM/DFM behavior, then fitment and startup behavior matter a lot. -
As seen recently on the Leno podcast that’s the purpose of the Slate truck. The ease of customizing. As entry level as possible. It does come with AC. -

Not sure how many wires you've got to play with BUT if there is constant power AND ground at the EGR how is it switching? In other words, the grounding via the PCM to activate it makes sense to me. -

Right?! Could you swap out the lights to an older style? Did they say what circuit it had to detect resistance on? It shouldn't be the running lights because those aren't on all the time, it could be the brake/turn signal circuit(s), but it seems that there might be a scenario where I would want the trailer brakes at the same time as when those lights first illuminate to recognize the trailer in the first place. If it's the 12v +, to charge trailer batteries, maybe adding a battery backup break away to the trailer would resolve the issue.
