Sicherung....Auspuffklappen

[Treurentner]

Hallo,

Also ein Soundfile hab ich nicht - wozu auch

aber so könnte man es auch optisch und elektrisch schick installieren:



Your first decision is whether you want to light a little LED in the switch to differentiate between the two modes. Since there is always power applied to the exhaust cutout fuse, the LED will be on when the switch is in the "quiet cruise" mode. The LED will stay on in this mode even when the car is not running. When the LED is off, the switch is in the "aggressive" mode. This means if you decide to go with the LED, you should always leave the switch in the aggressive mode when you shut the car down or you risk some long term battery drain. This is OK with me because I'll leave it in the "aggressive" mode 95% of the time.

STEP 1: Modify a fuse

The easiest way to make the mods to switch the fuse in/out is to modify a fuse so that you don't have to get to the wiring harness behind the fuse panel.



Always wire a fuse in line!!

Modifying a fuse without having it fall apart was the toughest part of this whole process. Buy a few extra fuses from the auto parts store and try to keep your cool! I used 18 gage wire. Make sure you epoxy or RTV the end of the fuse after you solder the wires to it to give it some structural strength.

Step 2: Remove the mounting panel

There is a little removeable panel in front of the center console glove box. Open the glove box and gentley pry out on the bottom of the panel to pop it out.



Step 3: Drilling the panel

The switch that I used required that a 15/16" hole be drilled in the panel. Since I only had a 1" spade drill, I used it and compensated for the tendancy of the switch to rotate by applying a little RTV to the back of the switch after it was snapped into the panel. If you use my approach for drilling the hole, make sure you have the panel well clamped or you will tear it apart while drilling. After drilling, smooth the edges of the new hole with sandpaper.





Step 4: Install modified fuse/harness and ground lug

The fuse panel is under the passenger footwell. Pull the carpet back and then flap the cover back to access the fuse panel.

If you want to light the LED you will need a ground return and I decided to attach a ground wire lug from the shielded electronic box mount screw next to the fuse panel.

I added an inline fuse that accepts the same mini fuses as the fuse panel to one of the lines running from the modified fuse/harness. I bought the inline fuse holder at Kragens Auto Parts (Cooper Bussman p/n BP/HHM).

Remove the existing fuse that is labeled as "spare" (lower right side of fuse panel) and plug in the modified fuse/harness into the fuse slot. Bend the harness into the right shape so that the modified fuse/harness wants to stay in the fuse socket.



Step 5: Threading harness along tranny tunnel

Pull the carpet and insulation along the passenger tranny tunnel back starting near the fuse panel. Pull the front part of the Emergency Brake boot back (there is a clip that pops out rather easily).

The wire harness is routed from the fuse panel and then in back of the tranny tunnel insulation and up into the Emergency Brake boot area. You can then poke the harness underneath the center console and into the cavity where the panel mounts.



Step 6: Attach spade lugs and connect to switch

Mount the switch to the panel (it snaps in place) and apply a little RTV to the back side so that the switch will not rotate.

Attach spade lugs to each wire and plug them into the back of the switch. For the Radio Shack switch the two fuse wires plug into terminals 1 and 2, the ground wire plugs into terminal 3.



Step 6: Pop panel/switch back in place

Snap the panel/switch back in place and enjoy your ability to change your exhaust note at will!
