2001 Volkswagen Jetta Turbo Timer Install & Mod

by LhYnxz Tue Oct 21, 2008 9:06 pm

Modification Explanation: Fuse #6 receives power from Ignition while the engine is ON. Basically this fuse tells the Comfort Control Module (CCM) that the engine is running and as a result, it will NOT allow you to use your remote control or arm your factory alarm. By re-routing the (0v/signal side) of the fuse to Key On wire, it will cut off power to the CCM when you remove your key from the ignition switch. Once the CCM does not receive a signal from fuse #6, you will be able to to use your remote control and arm your alarm. Listed below are the parts and tools necessary to perform this modification. Links are provided as examples where to purchase each item. NOTE: All electrical connections were joined together by soldering. If you don't own a soldering iron, then use plastic crimp style connectors which can be purchased at Pep Boys, Radio Shack, etc. WARNING: This mod was performed on a 2001 Volkswagen Jetta. I cannot gaurantee this will work on your vehicle. Work at your own risk. Installation times will vary upon the installer's experience. It took me about 60 minutes to complete this install and mod.
Items Needed: Turbo Timer (ie. Greddy Full Auto) Automotive Relay Automotive Wire (ie. 12-18 Guage) 4 Female Crimp-On Quick-Disconnects 1 Large Ring Tongue connector Solder Electrical Tape Zip Ties/Wire Loom
Tools Needed: Wire Stripper/Crimp Tool Soldering Iron Panel Removal Tool Small screwdriver and/or pick Razor Knife Torx 20 & 25 bits/driver Multimeter
Procedure: Step 1: (a)Begin by removing the 3 T20 screws underneath the column panels. (b)Insert the panel removal tool behind the top and bottom portion of the fuse panel cover and release the 4 panel clips. Remove the cover. (c)Pull the left column panel straight out to release the panel clips. (d)Now remove the T20 screw you see that was covered by the left columng panel.. (e)Insert the panel removal tool behind the top portion of the column panel and release the panel clip. Insert the panel removal tool behind the right portion of the column panel and release the panel clips. (f)You should now be able to remove the panel completely. a. b. b. c. d. e. f. Step 2: (g)On the left side of the metal support bracket, remove the 2 T20 and 1 T25 screws. (h)On the right side of the metal support bracket, remove the 2 T20 and 1 T25 screws. You should be able to remove the bracket completely. (i)Remove the 2 phillips head screws from underneath the column trim. There is also 3 T25 torx screws, 2 on the adjuster handle and 1 on the column trim. Remove all three of them. (j)Rotate your steering wheel and you will notice another 2 phillips head screws, 1 on each side of the wheel. Remove both of them and then the bottom column trim should come completely off. (k)Now you have full, easy access to the ignition harness. This is where you will tap into for +12v, Accessory, Ignition, and Key on power for the relay. g. h. i. j. k. Step 3: (l)Depending where you want to place your turbo timer will depend how much wire you will need to use. For this install, we mounted our turbo timer in the dash just below the air vent. For this, we will need to extend our harness to reach that far. First cut a piece of wire about 1 foot long and connect it to the Blue wire (Accessory) on the turbo timer's harness. Connect the other end to the Black/Red wire in the ignition harness. Solder and tape both connections. Repeat Step 3 for connecting the Green wire (Ignition) to Black and the Red wire (+12v) to Red). Since we are not utilizing the speed sensor option we taped off the Purple wire. (here is a drawing of the turbo timer wiring) l. Step 4: (m)Connect the brown wire from the turbo timer to the White/Yellow wire at the brake switch. Solder and tape your connection. (This wire works off a negative pulse. When you depress the brake pedal the voltage will read (0v). When you release the brake pedal, the voltage will read (+12v).) m. Step 5: (n)Remove the T25 screw just below the fuse box. This is where you will connect the Black wire from the turbo timer and ground wire for the relay. Cut a piece of wire approximately 1 foot long and crimp a female connector onto one end. Crimp a round connector onto the other end. Slide the turbo timer's ground wire and the small piece of wire you just cut between the metal frame and black plastic so there is a good ground connection. Insert the T25 screw back in and tighten. Make sure the wires are secure. (Leave the ground wire you made for the relay hanging there. It will be used later in Step 8.) n. Step 6: Please test the turbo timer and be sure that it works properly before continuing. Turn your vehicle on, set the turbo timer to a desired time (ie. 20 seconds). Turn the key to the off position and remove the key from the ignition switch. Your car should continue to run for 20 seconds. Depress the brake pedal and your vehicle should shut down. If so, continue to Step 7. If your vehicle turned off when you removed the key then you need to go back and check your connections and make sure everything is secure and attached to the appropriate wires.(Check for cold solder joints if you used solder. If you used crimp connectors make sure they are tightly crimped. Use your multimeter and read each wire you tapped into on the ignition harness. Ensure you tapped into the correct Ignition, Accessory, and +12v wires. Also check the ground connection.) Step 7: (o)Remove the 2 T25 screws that secure the fuse box in place. Then pull the fuse box out and unhook the black cover on the back. (p)Search for the Black/Purple wire behind fuse #6. Cut the wire several inches from the fuse. (q)Cut a piece of wire approximately 1 foot long and tap that wire into the Brown/Red wire (Key On) in the ignition harness. Crimp a female connector on the other end of that same wire. If you are not able to find a Black/Purple wire then pull fuse #6 out. Put your key in the ignition and turn the key to the on position. Using a multimeter, read each side of the fuse location. The side that reads +12v is the ignition side. The other side should read 0v. The 0v side is the CCM side. The wire behind that spot is the wire you need to cut and connect to the relay. (Some cars may differ. Refer to your service manual to locate the Key Power fuse if your unsure.) o. p. q. Step 8: (r)Cut 2 pieces of wire approximately 1 foot long and crimp a female connector on each of them. Connect the non-crimped side, of one of the wires you just made, and connect it to the fuse side of the Black/Purple wire behind the fuse box. Connect the crimped side to 30 post of the relay. Take the other wire and connect the non-crimped side to the other end of the Black/Purple going to the CCM. Connect the crimped side to the 87 post of the relay. Take the wire you tapped into the Brown/Red wire (Key On) and connect it to the 86 post of the relay. Take the ground wire you made in Step 5 and connect it to the 85 post of the relay. (here is a drawing of the relay wiring) r. Step 9: Please test the turbo timer and be sure that it still working properly. Turn your vehicle on, set the turbo timer to a desired time (ie. 20 seconds). Turn the key to the off position and remove the key from the ignition switch. Your car should continue to run for 20 seconds. Exit the vehicle and close the door. Press the lock button once and your doors should lock and the alarm should beep(armed). If so, continue to Step 10. If your vehicle turned off when you removed the key then you need to go back and check your connections and make sure everything is secure and attached to the appropriate wires.(Check for cold solder joints if you used solder. If you used crimp connectors make sure they are tightly crimped. Use your multimeter and read each wire you tapped into on the ignition harness. Ensure you tapped into the correct Ignition, Accessory, and +12v wires. Also check the ground connection.) If the turbo timer functions properly but neither the doors locked or alarm armed, then you need to go back and check your connections to fuse #6 wires, Key On wire at the ignition harness, and ground at the T25 screw underneath the fuse box. Step 10: (s)Now that everything is working properly you can clean up your installation by covering the wires with either wire loom or electrical tape. Secure any loose wiring with zip ties. Note : Be sure to leave a little bit of slack so that the telescopic steering wheel can fully move in and out as well as up and down. Reinstall all the panels in reverse order you took them off. s. Step 11: Your all finished! Test the turbo timer out and make sure everything is still working good. (It is possible to damage wires that were accidently left exposed when putting the car back together. Its always good practice to test your finished product once more at the very end A few examples of the finished product Enjoy your new mod and please tell your friends about this page
