Introduction
If you’re upgrading your Acura MDX 2008–2013 with an Android head unit, one common issue is the backup camera not working. Many owners think the camera is faulty, but the problem usually comes down to incorrect wiring.
In this guide, we’ll explain the reverse camera wiring for Acura MDX 2008–2013, covering power, ground, RCA video, and trigger wire connections, plus troubleshooting tips.
Why Reverse Camera Wiring Fails on Acura MDX
The Acura MDX is a little different from other cars. Common issues include:
-
RCA video connected, but reverse trigger wire missing
-
Camera powered by ACC instead of reverse light → camera always on
-
Poor ground → black screen or flickering
-
Reverse camera not enabled in the head unit factory settings (password 3368)
What You Need for the Install
-
Aftermarket reverse camera
-
RCA video cable with red trigger wire
-
Electrical tape / crimp connectors
-
Screwdriver & trim removal tool
Step-by-Step Wiring Guide
1. Rear Camera Connections (Trunk)
-
Red wire (+12V) → Connect to reverse light positive
-
Black wire (GND) → Connect to chassis ground
-
Yellow RCA video cable → Run to front head unit
-
(Optional) Small red wire along RCA → connect to same reverse light positive
2. Head Unit Connections (Front)
-
Yellow RCA plug → Insert into “Rear Camera IN”
-
Small red trigger wire → Connect to “Reverse/Back” input wire
-
Head Unit Settings → Factory settings → enter password 3368 → enable Reverse Camera
3. Troubleshooting Checklist
-
❌ Only RCA connected → No auto switch to camera view
-
❌ Camera on ACC → Always powered, shortens lifespan
-
❌ Loose ground → Black screen / static
-
✅ Correct: Camera powered by reverse light, trigger connected, reverse enabled in settings
