You had your chance to vote on the gauge color for Carter's GT-R and he has no choice but to go with it. We must say we're a little disappointed that nobody voted for fruity pink, but whatever. The winning color was blue, and that worked out well since Defi just released the new Blue Racer lineup. These are electronic gauges that are free of the gazillion different functions that most of you aren't going to use anyway, which keeps them a lot more price friendly than most gauges out there. So why not just make them manual? Because the readings from the sensors are quicker and more accurate. The gauges we went with are boost, oil pressure, oil temperature, and voltage. Signal Auto performed the install for us while we got a $9.95 oil change across the driveway.
1. You don't need a lift, but use a jack and stands at least. Drain the oil and remove the filter. | 
2. Use Teflon tape to wrap the threads of the pressure and temperature sensors. The sensors are sold by Defi and not included with the gauges. |
3. Find the right hole for each sensor on the oil filter sandwich adapter. Insert and tighten. No dirty thoughts. | 
4. It's really hard to see, but the sandwich adapter fits in the location of the stock ilter. The filter then bolts directly onto it. |
5. The harnesses for the sensors are short and need to be connected to the extensions so they can be run inside the car. | 
6. Grab a vacuum line off of the intake manifold, cut it, and slip the included T in place. This will be used for boost sensor reading. |
7. Search along the firewall. There should be an opening for you to run the wires into the driver's cabin. Use a coat hanger if you must. | 
8. Get under the steering column and find the wires you just ran. Start laying out the rest of the harnesses for the other gauges. |
9. Pop off whatever dash pieces you need to in order to be able to access a power source for the gauges and hide the harnesses. | |
