2004 MR2 Spyder new Head Unit(need help)

[tanner314]

I am trying to install a BOSS BV9976b for my MR2, but I don't know what the brown, white and cyan wires are for. In addition, I have purchased a backup camera and have found a route to connect it to the head unit. So far I have connected the two front speakers. Where do I connect the parking brake, the ignition switch, rear camera and memory backup?

You can get the wiring diagrams off ebay cheap

They don't make a book for my car so this was the only way for me to get my wiring diagrams.

DO NOT USE crimp butt connectors. Solder and cover with heatshrink tubing.

Why would anyone need a backup camera on a MR2??? I can understand an SUV or sedan but a 2dr, 2 seater convertible....
