I did finally get my gauges installed. I ordered one of the Speedhut gauges simiar to OP. Different color/light combo and also installed an Aeroforce Interceptor gauge.
I used a Lotek A-Pillar mount. I am not too sure I like this mounting option for myself. It's OK but fit and finish is not as nice as the factory pillar. I will likely install the steering column mount at some point.
While I was at it I also did the DRL disable. It was simply unplugging the current DRL relay from the back of the fuse block and installing a non-DRL flasher relay and junction block. I left the DRL relay connections on the fuse block should I ever feel like hooking it back up.
I had ordered and installed the 2013 Steering Column dimmer/headlight switch that offers DRL Off, but this did not function. So I just turned the DRL off full time until I can try a few more options. It may be that the DRL on 2013 is controlled by the ECU and if that is the case, and not controlled by the relay, then I will reinstall my 2012 dimmer stalk and keep the other part around for sometime in the future when it's worked out.
I really like the look of the speedhut gauge, mine has white face, trd logo, and it lit red when the lights are on; but I am not too keen on the Aeroforce Interceptor gauge because it's difficult to read with polarized sunglasses on. My only issues with the speedhut so far is that being electronic, or maybe that doesn't have anything to do with it, but the gauge doesn't seem to start reading boost for me until it reaches about 3-4 pounds. It just jumps to 3-4 pounds and doesn't come on smooth with its' reading even though I can hear the S/C'r around 2K rpm. Not too big a deal right now, but I am a stickler for details. I peak boost a little over 7lbs with the 2.85 pulley.
:: Regarding hookup of the gauges. On my Aeroforce, I simply have it running to the ODBII port as the only connection for now. That port also powers that gauge. I did prewire for an Add-a-fuse for switched ignition power but I messed up my 2nd one before install. I used an Add a fuse for the Speedhut in the 10A ignition 2 slot. I ran vacuum line through the firewall using the area/grommet that the hood latch cable uses. I installed the little inverter box that comes with the gauge under the dash near the fog light switch, and used the 12v power (t-taps) off one of the green power wires from the fog light switch to power the lights for the gauge. This is switched 12v so only when I turn on my lights will the gauge light. I grounded on some bolt that a bracket the fuse block uses to mount to the truck.
