I am wondering if anyone knows the wiring diagram for the steering wheel controls for the head unit, mainly which wire is volume.
i bought a new head unit for my 04 f150 truck and cant find the wiring diagram online to figure it out.
i know there are 3 separate connections.
1 main one for power, gnd, ant, speakers, etc..
1 for the subwoofer if your truck came with it which mine did.
1 for the steering wheel controls if your truck came with it which mine did.
i want to know what the different color wires are connected to on the steering wheel control connection. i have had no luck searching online for about an hour..
i know i could buy an adapter but really only want the volume to work and figured if someone knew i could just tap into that one wire and connect it to my new head unit.
Thanks.
I'm not sure what color wire. I'll have to search through my wiring manual, but all the audio steering wheel controls share the same signal wire. The only difference is the individual resistance of the buttons. If you have an aftermarket deck, you really need an interface...
I did not know that thank you. I saw there was a seperate connection for the steering wheel controls the connected to the back of the head unit with 5 or 6 different wires so i thought maybe one for the volume was seperate, did not know they ran off the same wire with a different resistance. in that case ill probably just get the adapter interface at some point. for now i guess i can be lazy and just reach for the buttons or use the remote lol. I appreciate the help!
