don't do color. for the sake of ur car.

as far as hiding ur wires go, i have never heard of anyone wanting to do that in the 5 years i've been tuning cars. if u want to color stuff yourself, the best and most popular thing to do is to sand ur stuff down to the nitty gritty, prime it, and spray it with high temperature enamel spray paint.

but once again, don't do it
