1. To start installing your new Mustang Mr. Mustang 10B942-L Instrument Cluster Wiring Harness, you'll first need to remove the original instrument cluster assembly. There are three Phillips head screws across the top and two at the bottom. Also remove the two plugs from the under dash wiring harness, and the speedometer cable.

2. Place the Mustang instrument panel on your work surface.

3. Turn the instrument cluster over. I labeled all the conductors because I originally planned to create my own harness. However, I had a hard time finding all of the correct plugs so I purchased this Mustang instrument cluster wiring harness, which made my labeling of the conductors unnecessary.

4. Examine the new Mr. Mustang wiring harness. All wires are adequate conductor size with correct size terminal plugs and wire gauge. It is also noted that all wire colors match the original.

5. To start the installation, I lined up the harness with the cluster and started from the left and replaced every connection, one at a time.

6. Then, again starting on the left, I removed the first Mustang instrument panel light bulb, relocated the bulb to the new harness and inserted the new cluster lamp.

7. I replaced every connection, one at a time, until the old harness was completely disconnected. The photo below shows the original cluster with the new Mustang instrument cluster wiring harness completely installed.

8. Replace the instrument cluster, connect the Mustang Mr. Mustang Instrument Cluster Wiring Harness to the under dash harness using the two plugs, and enjoy.
