Civic EG

but everywhere i've looked i CANNOT find a harness to fit my car
can anyone help me with a link of a cheap one?

i am installing a Dual DVD player, if that makes a difference.

Here ya go, don't know what car you have but this should work for you. You will just have to put the deck harness and the car harness together, but its easy.
Hope this helps.
