Vehicle-specific wiring harness

This Metra 70-1781 harness plugs directly into the factory radio connector on Mazda vehicles from 1986 to 1989 and Mazda trucks from 1986 to 1993. It also fits certain Kia models from 1994 and Ford models from 1988 to 1993. The adapter provides connections for power and four speakers without cutting original wiring.

Installers avoiding wire splicing

The plug-in design suits anyone replacing a factory radio who wants to keep the vehicle harness intact. It is not for vehicles outside the listed model years or for installations requiring connections beyond power and four speakers. Buyers needing steering-wheel control integration or amplifier turn-on leads should look at a different adapter.

Questions about this item

Does the 70-1781 harness include any mounting hardware or tools, or must those be purchased separately?

The package contains only the wiring harness that plugs into the vehicle harness at the radio location for power and four speakers; no brackets, screws or tools are included.

The title lists Mazda 1986-1989, truck 1986-1993 and Kia 1994 — how do I confirm which version fits my vehicle?

The single 70-1781 part covers all three applications; match your exact year, make and model to the ranges shown — Mazda cars 1986-1989, Mazda trucks 1986-1993, or Kia 1994 — to verify compatibility.
