Sonic - why not buy online ?

I buy my wiring harness product from sonic; they are cheaper, have the product when they say they do, and ship quickly.

I don't think my local electronics store does any of the above.

Plugs right into a the original stock harness.

It is a perfect fit for my truck. It is easy to wire everything outside the vehicle for an easier installation and maintains the value of the vehicle.
