So I checked those wires. Verified I'm getting Voltage to Pin 26 When Ignition is switched on, then getting no voltage when switched off. Verified Pin 17 has permanent 12V. Diode was oriented correctly. Removed Diode (located in the fuse box and soldered into a Buss fuse adapter) to check for back voltage from pin 19. None. switching off and on I get a constant 4 Ohms of resistance. there is no change in readings. With the diode in I get constant voltage across the diode heading to pin 19 whether the ignition is switched on or off. It seems as though the relay actuation circuitry is not grounding, but I'm not sure what to do now, I've already tried a different ECU and cleaned all the ground connections I could locate.
