Dash Rehab Part 5: Gauge Overview and Test Drive

Dash Rehab Part 5: Gauge Overview and Test Drive

In Part 4 of our Dash Rehab series, we showed how we wired the gauges up in a wiring harness as well as how we wired each of the major sensors. Wiring them in this way made installing them very simple. We plugged in the two wiring harnesses we created plus the GPS antenna for the speedometer and then bolted in the panel. In this installment, we will reveal the end product, take a test drive to show how everything is working, and provide a full break-down of all the costs involved in the project.

Raw Materials

Our project started out with two pieces of 14-gauge aluminum sheet from our favorite local metal shop, AZ Metals. One sheet measured 28" by 6" and the other measured 28" by 14". These cost us $19.30.
Total: $19.30

Processing Metal

Once the aluminum panels were all cut and shaped, we sanded them and sent them off to be anodized black at Anodizing of Mesa. This cost $50 for both pieces. After that we had the pieces laser etched at The Leading Etch to label all the lights and switches. This was $50 for both pieces also.
Total: $100.00

Switches, Lights, and Gauges

Next, we purchased all new heavy-duty toggle switches and extensions (the chrome pieces that makes some of the switches longer). We bought these on Amazon for $72.59 (full links to the exact products we purchased will be listed below). We also bought an additional chrome button for the windshield wiper fluid for $8.28 (it was a pretty fancy button). We found LED indicator lights in red, green, blue, yellow on Amazon for $17.98. The USB adapter for the 5V signal generated in the back was purchased from WalMart for $4.99. We purchased the "Legacy" Gauges from Speedhut.com for $1,119.65.
Total: $1223.49

Final Tally

$1342.79 For all new warning lights, switches, gauges, and panels.


The ability to customize the Speedhut gauges is pretty amazing. They have an online designer that allows the customizing of just about every aspect of the gauges: colors, fonts, ticks, custom logo and text, backlight color, bezel - the number of options is unreal. They look incredible. More importantly, the new gauges and sensors are working great. In our last post, we explained how and where we installed each sensor as well as how we verified that they were working correctly. We have been using the gauges for about a month now with no issues at all.
