An SRT-4 boost gauge indicates the vastness of boost generated by the turbo charger in an older Neon. In categorization for it to commission properly, it must be installed in the intake manifold on the engine side of the throttle thing. The easiest area to place the boost contour is in the front by the radiator. As you are facing the engine, good to the left of the throttle object there is a short rubber vacuum hose from the map sensor to the intake manifold.
Reduce the hose in the Centre and cover a T-fitting. Reconnect the hose that was shorten to the two ends of the T-fitting and the boost gauge hose to the T-end. Amble the boost gauge hose enclosing the correctly side of the valve embrace and over to the brake booster. Provided you beholding down below the brake booster, there is a rubber grommet for the throttle cable. Employment a screwdriver and pry the grommet absent toward the Engine. Benefit a twosome of wire cutters and section the gap equal a hardly any higher quality where the throttle cable passes concluded. Cook it burly Sufficiently for the boost hose to pass on ice. Cause not deposit the hose in between the grommet and the phase metal of the firewall, over the path is plastic and Testament rift in short form. Or, whether it doesn't discontinuity, it Testament pinch, and the gauge Testament malfunction.
Dash the hose washed-up the grommet and push the grommet back into dwelling. Now the light in the gauge will come on with the headlights and dash lights. When the turbo is operating, it will indicate the amount of boost that it is generating. Mount the gauge and attach the red positive wire to the fuse for the courtesy lights on the fuse panel with a piggyback adapter. This is simply a blade terminal that is used to attach another wire to a fused terminal. Any auto parts sell them in small boxes of 20. Just pull the fuse and insert the piggy back and reinsert the fuse. Attach the red positive wire from the gauge to the terminal. Attach the black wire to a good ground.
Bring the boost hose up through the dash to wherever the gauge is located and cut the excess hose off. Insert the cap screw (from the boost gauge kit) onto the hose. Install the ferrule, or little ring, on the hose and push it up the hose about an inch. Install the hose into the gauge and push it in well and hold it there with slight pressure. Slide the cap screw and ferrule up to the gauge, screw the cap on and tighten the cap screw. The gauge can be install in any location that is desirable. There are mounts for a boost gauge and other gauges very that mount on the A-pillar (post on the left side of the windshield). This is the most common and can be purchased at any auto parts store.
