Thank you all.for the advice. It seems this install might be more challenging than the RCAs. The HU I just received is a 2din with back up camera. It has one set of left and right outs of RCA. The others are for AV and camera, which are V1 and V2 out, CVBSIN, and CAMIN. I'll figure all that out later, for now I'm just trying to research some.of these pigtail wires. Since my phone's camera won't capture a decent enough photo of the diagram I'll try my best to type what it say. I'm having trouble figuring out a few wires. The green, pink, brown and orange. Maybe some of you have come across a Chinese "piece of work" like this before.
Pink - Parking Sensor Control Wires +12v
Orange - Parking Single Check
Brown - Key
Green - Head Lamp
The rest are familiar Wires I should have no problem with. But I'll list them so you know that they're covered, possibly help with process of elimination.
Blue - Power antenna
Yellow - B+
Red - ACC
Black - GND
I'm guessing that these wires (pink, green, orange, brown) have something to do with the back up camera, and some have to do with a steering wheel control which I don't have. I guess what I need help with is finding out which would be:
1 - which should be ground for DVD to work, so kids can watch while I drive. I read somewhere that there's a wire for the backup camera ground that affects the screen play if not using emergency brake, and that I can simply bypass that by hooking it to a constant ground. My guess is the pink, but the diagram shows it with a +12v.
2 - The orange wire, says Parking Single Check. I'm confused to what that means.
3 - The green wire, it says Head Lamp. Is that the chinese translation for dimmer? I've never had.to hook a radio into head lamps before.
4 - The brown wire, it says Key. I read somewhere that this is for steering controls, which I don't have. So this might not be used. But I have to ask because the metra adapter harness to hook up to the factory wiring of the vehicle has a brown wire, but I believe it's labeled Mute and not used.
Ok I think for now I will wire in the basics. I've got plenty to do with the speakers and amp for now. This other stuff can wait until I get a better understanding of what's what. Since there is only one set of RCAs I'm going to run those to the sub amp, and use the speaker wires to the 4 channel amp then out to door speakers.
The radio I think is made by AMPrime and the model is 7010B if that helps at all. I'll post the pic I took of the diagram in book, but it's horrible. I did however find a pic online of one very close to what I have. I'll post that too since it may be of some help.
Once again, thanks for all the input. I seriously appreciate all of you.
Would it be ok to run the speaker wire from the head unit to the high level input on the 4 channel, and use the RCAs for the 2 channel sub amp?
Yes. That is exactly what you should do and it is okay to do it that way. Perfectly fine. What kind of head unit? If it has only one pair of preamp outputs... you know where I'm going with this. Adding RCA splitters will cut voltage in half resulting in lower quality sound.
Might be time to upgrade. Idk
