Supplies




Blitz Dual Turbo Timer - DC Version

Steps

  1. Remove the lower dash panel, two screws below and one plastic screw on the left side panel. Pull from the bottom to loosen and the pull the top parts straight out. Rest panel on floor.
  2. Look for the blue connector for the ignition wires. Looking in with the tab on the left, the wires are as follows:
    Top Right - 12 +
    Bottom Right - Accessory
    Bottom Left - Ignition
    Ignition connector at the base of

 the steering column
    You can either connect the harness, or splice into the factory wires if you did not get a harness. Only attach the 12+ and the Ignition wire, do not attach the accessory wire to the turbo timer.
  3. The accessory wire at the ignition juction must be tapped and a length of wire must be run to the alarm module located above the fuse panel. Look directly above the fuse panel and you will see it. Remove the connector and look for a dark green wire with a black strip (there are two green/black wires, make sure it's the darkest green of the two). Cut the wire and attach the length of wire to the module side. Tape off the extra green/black wire.
  4. Another juction must be made from the accessory wire from the ignition harness. This must go to the other alarm module located in the center console.
  5. Remove the plastic piece that surrounds the parking brake (piece where the mirror controls are). Pull up from the back, it's just a snap in piece.
  6. There is a grey wire that goes to the sensor module. You must cut this wire and splice the accy wire on the module side. Tape the extra grey wire to the side. This splice will allow the alarm to be set while the TT is counting down.
  7. Ground the TT, and then mount the remote panel.
  8. Test it out and then put the car back together and have fun.

    editor note: add pink wire hookup info for parking brake later

    Boost Gauge Hookup

    • Look at the firewall from the engine compartment on the passenger side. Look low and you will see a grommet that will let you in near the passengers feet.
    • Run the hose from the gauge through this grommet and remount the grommet in the firewall.
    • Use some silicone adhesive to seal gaps in the grommet, otherwise rain can get in and get your feet all wet!
    • Set the hose aside
    • On the passenger's side of the front intake runner, there is a vacuum hose that runs to the FPR (fuel pressure regulator). Look under the steering pump and you will see a 2" hose! We'll tap this hose to get boost/vacuum to the gauge.
    • Remove the hose and prepare some lengths of hose. The TT fitting will not fit in there, so you have to use some longer pieces of hose. Use some lentgths, about 3-4" each to find the right size.
    • Assemble, and use zip ties to secure each end (like a clamp) and trim the excess piece off.
    • Double check all your fittings, then start the car.
    • Listen/check for leaks. You won't get a boost reading unless you are driving the car under boost. Revving while stopped will not create positive boost!
