        Do these come with detailed instructions for installation? It doesn't look like much if any wiring is involved, just plug and play correct? Thank you!

        • Yes, an installation guide will be included upon the arrival of your package. As for the install, yes it is as straight forward as it seems, just unplug the old stuff and plug this right in. However professional recalibration of your Mustangs speedometer will be required as this overlay insert reads 140mph verses the factory gauge reading 85mph.

        If you have a speedo only ranging to 85mph will these gauges work?

        • Hello! This White Face Reverse Glow Gauge Insert will work on 85mph speedometers looking to convert to 140mph as long as re-calibration of the speedometer is performed.

        I have an 88 Mustang mclaren with the Speedo reading 85mph. Can the 140mph fit over the original one with no see through issues? I know I’ll recalibrate speedo but want to make sure it looks correct/right.

        • The White Face Reverse Glow Gauge Insert uses its own lighting for the reverse glow functionality, so no bleed through will be created. This will work flawlessly on 85mph speedometers looking to convert to 140mph, as long as re-calibration of the speedometer is performed.

        Who can perform the "professional recalibration"? I would like to replace the look of my gauge cluster with this kit, but who would I get to perform the required calibration? Is this something that can be performed by my local Ford dealership or would I have to track down some specialty shop? 3 answers

            This was a straight forward installation. The wiring was a bit delicate, but if you take your time it will work out okay.

            Better wires

            Once I finally got the gauges installed they looked good but, the wires that are in the kit are entirely too thin. When splicing the inverter into the headlight switch it would not get a good connection due to the wires being so thin. Also the center gauge piece is too small and does not line up correctly.

            Take your time and mark where your gauges are pointing. It requires the smallest amount of trimming where you can't see.

            Reverse Glow Gauge Overlays-Review

            The overlays look and work great, once you figured out how to install them over the OEM gauges, They do not install directly over the gauges , you have to maneuver them. . The problems I experienced were these, the overlays really should have a small square or dot or double sided tape to keep then in place and I unscrewed the screws holding the OEM face plates on ( you have to remove the left side to get at the nuts on the alternator gauge), I used the screws and scotch tape on the top and bottom edges to secure the overlays, the second problem was the instructions did not make it clear how to fit the left and right gauge overlays over the OEM gauges without taking the needles off first. I finally figured out that if you moved the overlay under the needle and pushed it as far towards the opposite edge you could get the overlay to clear the humpy part at the back of the needle . Otherwise it was worth the effort.

            They were easy to install and look very good. Now there needs to be the same for the A/C, heater controls. That would finish off everything the same.

            Perfect touch to brighten up a 90's gauge cluster. I didn't like the old dark look. The install was easy, and it looks great. A must have item if you have stock gauges.

            I purchased the reverse glow gauge and it was easy to install. It makes my dash light up really nice. The instructions are easy to follow and gives my car a special look. Since then i purchased more pieces for my car and I'm very excited to have American muscle help custom my dream ride.

            Nice touch to any exterior blue color stang

            I have not installed these in yet, due to pin pointing and fixing my speedo, odometer, fuel gauge, and volt meter, but I have placed these inserts in temporarily and they look great during the day and killer at night, especially if your own/drive a exterior blue colored stang. I'm keeping in theme with blue back light gauges, CD player head unit, and monster tach light. Can't wait to permanently install these inserts once I get my running gauges working in proper order. Even if you don't have a blue exterior stang, I can see these working with any exterior colored stang and adding some interior flair and a cool glow for summer evening cruising. Thanks for the great product AM!
