    Aquamist HFS-4 install

    I recently purchased the Aquamist HFS4 kit from Protuningfreaks and finally got around to installing it. I chose this kit because Iím flash only and when you add all the features and items that you get its worth it. Mods are in my sig and I will be getting a ptf protune shortly, but this thread is just to help others with some alternatives and insight on install methods that Iíve come across during my research.
    My controller is mounted like many others in the glove box. Itís actually behind the glove box panel that is used to access the fuses.

    From there I shrink wrapped and routed the power harness to the front cigarette lighter harness under the center console. This provides the +12, ground, and Dim needed for the guage.
    (Pics coming soon)
    The ECU and User harness were routed the same way as the JB4 usb cable through the firewall directly into the DME box. Most likely your kit will come with the posi-taps and those make it easy to tie into the dme wires.

    I mounted my gauge on the dash as seen in the pics and routed to cable under the dash board to the glove box. I also used this route for the FAV and Flow sensor harness and passed them through a grommet on the driverside firewall.

    The Trunk harness was routed along the passenger side under the doorsills and to the trunk. I have my pump and tank mounted on the driverside of the trunk. My tank placement may change because I thought the DO tank would fit perfect in the corner with the pump mounted to it. I guess the e90 trunks are not like the e92s that Iíve seen where the tank is mounted.

    I wanted to be different and decided to plug my power cable for the pump harness directly into the distribution block on top of the battery. You will need to buy the2 pole socket housing and flat-type connector, which were a couple of bucks at the dealer.

    The 6mm hose was ran through the vent on the side panel and comes out behind the rear bumper. Then I zip-tied it to the fuel line and ran it underneath the car up to the engine bay.

    The FAV is mounted to the power steering bracket.

    I tapped into my ER CP right after the elbow for one nozzle while the other is tapped into the intercooler outlet pipe. PTF suggested this way for cooler iats and better atomization.

    Well thatís my install and I hope it will help others with theirs. All in all it wasnít as hard as I thought it was going to be. Now Iím waiting to get the meth map from PTF to take full advantage of the kit.

    Great right up! @alpinedevil335 helped me install mine last Saturday as well. The wiring we found to be the most difficult part but we finally got it figured out.

    Interesting to see more and more folks tapping the IC end tanks or J pipe...I really should do that. Spraying solely via the CP seems overly rudimentary.

    Nice writeup OP

    Has there been any significant data to prove that tapping into the IC yields better gains though?

    I think if you're running upgraded turbos and you need to have a dual setup then this would be ideal.
