We find the information can be scattered all over the internet and want this to be a centralized place where we can talk amongst each other and share our questions and answers that may be able to help others going through similar Hemi swap situations. Please be kind to others and help out where you can while getting the information you need. Blake and Mike will be admins and answering questions here as well!

ASD Activation Conditions

in General Discussions

Hi, I have the Mopar crate ecu and I believe I have it wired correctly but the ECU will not send the ground signal to the ASD relay or the fuel pump relay when I hit the switch. I have the following wires pinned in these locations:

96:12v constant power

72, 52, 53: Ground

23: 12v from ignition switch 80: ASD relay control (pin 85 on asd relay as ground)

74,75,76: ASD Feedback (from asd relay output)

73: Fuel pump relay control

I know the relays are fine. When I touch them to ground I can hear it click and the fuel pump actually runs when I manually ground it. Do I need to anything else in order to have the ASD relay activate? Does it require a neutral safety signal or anything?
