69 Dodge Charger, DEI 530T & Avital 5303

While it will probably work fine without diodes, many installers recommend placing them across the relay coil. I've done it both ways. If you choose to use them, just make sure you connect the striped side (cathode) to the side with positive voltage connected. If you try to connect them the other way they will explode when powered. Verify your power and ground connections, then check fuses. If you have no issues there, verify the power lock/unlock outputs on the alarm.My ex once told me I have a perfect face for radio.

My bad, I wired one of the relays wrong. Doors are now fully functional! No power to the windows yet so I have to trace a few wires but I'll find it.

I have power to the windows but the 530T modules are not working for some reason. I can operate all 4 windows with the master switch, and I can operate both passenger windows with their individual switches. The driver side rear window switch is not working though. I tried another and still no go so not sure what's going on. When I hold the Aux button on the remote for a few seconds I can hear both 530T modules click, but that's all they're doing. Fuses are good. Where do I start looking?

If anyone is still reading this, I found the issue and everything is working as it should. It's pretty cool to have all these upgrades in an old Charger.
