05 Mazda 3
 

Hey there, I just got my sub, and I have the extension cable and whatnot, but I need help connecting to my factory HU.

I have an 05 Mazda 3, and here is a picture of the back.

Attached is a picture of the rear of the HU. MThe connection is the laft side, (not the red arrow, as I pulled this image off the internet).

I have the 7901 connector, but that doesnt work. I would prefer to do this without splicing all the wires.

Thanks in advance!!
