## Questions & Answers

**Q: Will this work on a 2005 Mazda 3 and do the colors of the wire match with the factory wire colors in order?**
A: The wire colors corresponded pretty closely as far as arrangement order in the harness itself. I cannot say if it will work in the Mazda 3 because I installed in a Mazda 5.

**Q: Do these colors really match, the power wire on my master plug is red but on the harness it’s yellow, does that mean the yellow is my power wire?**
A: No yellow is so the radio will hold its memory. Look it up on YouTube to find the correct wire positions.

**Q: Does this include 1p and 1n wires for the swc to work?**
A: When connecting steering controls you will need to connect to the factory side of the wiring harness. These pins are not on the 70-7903 harness.

**Q: Does this fit a 2003 Mazda 6?**
A: The correct kit to install an aftermarket radio in this vehicle is the 99-7523S. Which contains the harnesses and dash plastics.
