I have cleaned up the instructions based on the updated wiring diagram and video skrimo posted. I did this because I was confused after reading the instructions. But after seeing the video I came to the conclusion that "before" and "after" were being used instead of the words "splice" or "split". Hey, its all good skrimo. I think I got it figured out and will be putting it together today on the bench.
1) ACC wire
- Splice ACC wire - connect one lead to 12v Relay #1 at pin 85 and connect second lead to 12v Relay #2 at pin 85
2) 12v Constant BAT+
- Splice 12v Constant BAT+ - connect one lead to 12v Relay #1 at pin 87 and connect second lead to 5v Delay Relay COM
3) 5V Delay Relay NO
- Splice lead from 5V Delay Relay NO pin - connect one lead to 12v Relay #1 at pin 30 and connect second lead to 12v to 5v Converter at 12v IN
4) Main Ground (GND)
- Connect 12v Relay #1 pin 86, 12v Relay #2 pin 86, and 12v to 5v Converter to Main Ground GND
5) Raspberry Pi to 5V Delay Relay
- Connect GPIO 5v pin 2 or 4 to 5V Delay Relay V+
- GPIO GND pin (6,9,14,20,25,30,34, or 39) I will use GPIO GND pin 6. Connect GPIO GND pin 6 to 5V Delay Relay GND
- GPIO pin (x) connect to 5V Delay Relay IN
6) Rasberry Pi to 12v Relay #2
- Connect GPIO 3.3v pin 17 to 12v Relay #2 at pin 30
- Conncet GPIO pin 23 to 12v Relay #2 at pin 87a
7) Wire up power connections from 12v to 5v Converter out to Raspberry Pi and Monitor as desired.
If you use different GPIO pins to connect to the 5v Delay Relay or 12v Relay #2 you need to modify the scripts to reflect the pins you used.
