Hello, I bought a radio for my car and tried to install it for the first time ever today. I bought the proper harness and began to install. I only have two speakers in my car so I connected red (power) to red green to green purple to purple yellow to yellow etc. My harness had a wire option for dimmer and another for dashboard however my radio did not have wires to connect with these. I cannot get my dash lights to work and it is very annoying and dangerous. I even tried unplugging everything and it still won't work. Any ideas?
