While you may learn too much information about your pal after hoisting a few beers at the local pool hall, you can never have too much information when it comes to your vehicle’s operation. Oil temperature and pressure are like the blood flowing through your body, if it stops or gets too hot, you’re a dead man; the same goes for your engine.
To that end, we decided to add a few more gauges to our 2007 Ford Mustang GT. While the gauges in our dash were a great start, we wanted something more than vague guesses at oil pressure, boost and voltage. To that end we selected a set of GlowShift gauges. These fully illuminated gauges were a nice addition to the interior and were very simple to install, taking less than an hour by novice artisans. The dials are easy to read, with actual numbered faces — wow — what a difference.
Follow along as we demonstrate the correct techniques to the installation.
- Our 2007 Ford Mustang GT was a great car, but knowing the status of critical engine functions was, well, lacking in terms of style and information. The fix? A set of GlowShift gauges.
- After disconnecting the battery, we removed the oil filter and checked for clearances by holding up the GlowShift oil filter sandwich plate adapter. It may be necessary to adjust some of the wiring harnesses in this location in order to install this component.

- Install the GlowShift oil pressure sending unit using Teflon tape. Install the oil feed line or any other sender at this time to the GlowShift sandwich plate. If no other accessories are being installed, install the provided plugs. [b]Important:[/b] Teflon tape must be used to stop potential leaks. Install the GlowShift oil sandwich plate where the oil filter mounts up. Do not over tighten or the gasket may tear. It should be a little more than hand-tight, similar to an oil filter.
- Reinstall oil filter to the GlowShift sandwich plate.
- Run a 16-gauge wire from the “wk post” on the GlowShift oil pressure sender to a good ground.
- Run another 16-gauge wire from the “g post” on the GlowShift oil pressure sender up to the firewall. Leave extra wire length here so you can feed it through the firewall and up to the gauge later in the installation.
- Find a good vacuum source off of the intake manifold and install the supplied T-fitting. Install with the brass fitting going towards the gauge. If there is a fitting on the supercharger or intake manifold to hook up an additional line, the T-fitting must be capped and installed inline with the gauge.

- Behind the inner wheel well on the driver’s side is a wire harness and rubber grommet. Cut a small hole here so that you can get the oil pressure signal wire, vacuum line, and any ground and power wires through the fire wall. Make sure that the hole is not so large that water and air can get in, but make it big enough so that it does not restrict the boost and vacuum reading on the gauge. Run the oil pressure sending wire to the GlowShift oil pressure gauge and connect it to the green wire on the gauge.
- Run the vacuum line to the GlowShift boost gauge and secure tightly.
- On the GlowShift boost gauge there are four wires. The orange and purple control the lights on the needle and dial. The yellow is the memory wire for the colors and the black is ground. You must connect both the orange and the purple to a 12-volt ignition switched voltage. For example, a good source that turns on and off with the key is the radio. The yellow wire needs to be connected to a 12-volt constant voltage, and the black wire needs to be connected to a good ground. This gauge does not have connectors, so we recommend that you use a male and female style connector to install this gauge.

- On the GlowShift oil pressure gauge, there are four wires. The red controls the lights on the needle and dial. The yellow is the memory wire for the colors. The green is for the oil pressure signal from the oil pressure sender and the black is ground. You must connect red to a 12-volt ignition switched voltage. The yellow wire needs to be connected to a 12-volt constant voltage. Run the GlowShift oil pressure sender wire to the green wire of the gauge and the black wire should be connected to a good ground.

- On the GlowShift volt gauge there are three wires. The red wire controls the lights on the needle and dial as well as read the voltage that the alternator is putting out. The yellow wire is the memory wire for the colors and the black is ground. You must connect red to a 12- volt ignition switched voltage. The yellow wire needs to be connected to a 12-volt constant voltage, and the black wire needs to be connected to a good ground.
- Here’s the final appearance of our new gauge ready to roll. These easy to reach gauges can be turned to aid readability or for quick reference to make the needles from several gauges all read off the same direction.
