Today I installed my Prosport Premium (with peak) using 08SubieWRX's A-pillar pod he made for me. Install went pretty smooth, I'll go over the basic process I did.
Since I don't have easy access to a jack and stands, I decided to keep the wheel on for this install. First, I turned the wheel so that I had plenty of access to the wheel well.
This gave the me ability to take off part of the fender liner. The main two pop's are displayed here.
You must also remove part of the side skirt, and then remove the fender grille piece. Start by popping out the plastic pops under the side skirt up front.
Then remove just pull the side skirt, it will pop loose.
Next, starting at the top of the fender piece, pull it directly towards you, working your way down till you get it off. After removing this piece, you can start pulling out the fender liner, eventually you'll get it to right about here:
Unplug your BOV's vacuum line, and install the T-fitting that came with the gauge. I DID NOT CUT my stock vacuum line, there is no need to do this! All I did was add on a small piece of new vacuum hose that I found at my lab, literally it is only 3" in length. I then connected the sender using the supplied nylon line.
Next, setup the sender unit somewhere in the engine bay, and run the sender wires through the side of the fender as seen here.
Eventually, you'll fish the line through and it will reach as seen here.
I then ran the cable directly through the grommet seen here, I did NOT cut the grommet, I simply added it underneath the bottom side, and then pulled the grommet back over top of the wire. There seems to be no gap, and I'll be watching for any strange issues.
Finally in the interior.
Once you get to this part, your basically 90% done. All of the hard work is finished, now it's up to your location of the gauge (SMY cluster, A-pillar, stock mount, etc.) in how you decide to route your wiring. I constructed my own harness using the stock Prosport supplied harness.
Seen here is how I decided to get power; I hooked up plug and play fuse taps that are 100% reversible and do not damage the fuse box. I also installed a ground prong (ring terminal) that is able to be screwed down into a chosen spot. All the wiring is done with butt connectors and shrink wrap, which is all wrapped in electrical tape. Didn't feel the need to use the plastic sheathing since it will never see the outside.
Finally, I removed the A-pillar.
Pull towards you not to the side..
I then fished the wires through the A-pillar gauge pod, replaced the new A-pillar with pod, connected the gauge, ran the wires down to the fuse box, installed them as
Red: #3 fuse titled "DOOR LOCK"
White: #31 Fuse titled "ACC"
Amber: #16 fuse titled "ILM"
Finally, this is the end result.
Daytime is white, for better visibility.
Nighttime is amber, white is too bright anyway.
