Default Sony XAV-AX5000 & Backkup Camera Install 11 STi Non-Nav

Hey all,

I'm about to install a Sony AX5000 HU and a AUTOVOX backup camera(BUC, for short). I would like to preface by saying I have very limited electrical knowledge & tools but I am buying cheap things here and there on Amazon and learning as I go.

I have a harness to splice all Sony harness cables in order to match up to the factory 20-pin. What I'm currently stuck on is a reverse signal in order for my BUC to trigger when in reverse, automatically. I found here, according to SVXdc that I should be looking for the BROWN/YELLOW cable under the passenger foot well, nearest the door. My Sony reverse signal in lead is far too short to reach this area and as such I would need to extend this lead. Does anyone know what gauge this wire is? I also don't entirely understand how to splice the BROWN/YELLOW cable; do I snip it from the harness it's attached to and instead attach it to the cable from the Sony HU or do I use a T-Tap/Vampire tap into it without changing any of the existing lay out? Also the BUC includes a red and ground/black lead which need to be connected. The ground I know to connect with all the other grounds, does the red from the BUC splice into the red from the Sony HU?

I also bought a right angle 3.5mm jack as I understand it can be spliced into the existing steering wheel controls (SWC). According to this guide, I would match the 3.5mm jack wires to the harness but my harness doesn't seem to have the necessary leads, can someone confirm? This is the one I was provided and this is one I found on amazon.com that might be what I need?

Thanks in advance!


- Not super savvy on electrical wiring currently, also not stupid and will do things with caution.
- Don't have a multimeter on hand but can get access to one if need be.
- What gauge wire do I need to extend the Sony HU Reverse In lead (about 40")
- How do I splice this Reverse In wire to the factory BROWN/YELLOW reverse signal under passenger foot well?
- Can I use a t-tap or do I snip from the harness and connect to the Sony HU lead?
- Is my 20-pin missing a few leads and should I get a different one?

I heard sony integrated there object recognition software.
As for me, this is great for security systems. It captures the face parameters and makes clear photos.
