Saab 9³ 2003+ Tel1 EHU Leads DIY Installation Instructions

These instructions are intended to be used by a person with moderate skill. More involved than changing a wiper blade, but less than installing a subwoofer.

 !Please read all instructions prior to actually diving in!

Standard disclaimers: While Saabs in general are put together very intelligently, with parts that are meant to come apart logically & easily, please use your own judgment in how much force to apply. If you feel as you’re going to break a clip, stop, reread the instructions, perhaps interpret them differently, then try again. If that still doesn’t work, ask for help. Lastly, ask your dealer to do it. Etadyne Industries LLC or Nova Technology Inc. will not be held liable for turning your warranted car into a big paperweight.
    Also, these steps are performed on a left-hand drive vehicle.  It is expected that all these steps are the same for right-hand drive vehicles.  If not, please let us know!

Tools you’ll need to complete this installation:

            Etadyne recommends using the Removal Tool from Saab, part# 8293474

Step 0: Quick notes.
    -These instructions are for a 2003 US Arc with single CD player & automatic climate control.

    -The only difference between manual & automatic climate control is that manual has 1 plug in the back instead of 2 for the automatic.  Faceplate removal & re-installation is exactly the same.

     -The only difference between a single CD & 6-CD changer is...nothing.  Removal & re-installation is exactly the same, and it does not have any different connection method.  The Aux-in plug used for this installation is still available.

Step 1: Prepare a work area.
    Activate the parking brake & put the vehicle in Drive. You can do this by turning the ignition to the “On” position, pressing on the brake pedal, shifting into Drive, pulling the parking brake lever, releasing the brake pedal slowly, and turning the key to "Off".  Also turn the radio off & eject all CDs (if you don't, while the unit is out you may hit the eject button causing them to be ejected unintentionally).
     This allows you to pull the radio out of the center stack without hitting the gear shift. We do not have access to a Manual vehicle, but the procedure may be similar. Place the towel in between the gear shift & the ashtray, as this is where the radio, or Electronic Head Unit (EHU) will rest while being worked on. Also note: while disconnecting the vehicle battery is not needed since no power circuits are being worked on, the stereo should not be on.

Step 2: Remove & unplug HVAC faceplate.
    Insert the butter knife in between the far edges & grained soft plastic trim about 4mm & using a prying motion, gently pry edge away & forward towards you. Repeat for the other side. While prying, slide the knife from top to bottom until the catch is found. If you are successful, the faceplate will quietly pop out with a minimum of fuss.  The picture below is for the automatic climate controls, but manual controls are removed exactly the same.

Pull the unit towards you, stretching the 2 cables that attach it. Pull the maroon clips that hold the connectors outwards. They will extend 10mm, and take a little bit of force. Once extended they will automatically unplug themselves from the HVAC unit. Place the unit someplace safe for now. NOTE: Manual climate control will only have 1 cable.  This does not affect removal.

Step 3: Remove EHU.
    There are 2 clips holding the EHU in. They are thin metal, so too much forcing will deform them. Staring on one side, gently push forward edge of the clip inwards so it touches the metal. Repeat on other side. Then pull the CD player out. This is a coordinated effort of pulling the CD Player & keeping both clips inwards.

Eventually you will work the CD player loose. The EHU is attached to it, on top. Gently slide it towards you. Take note of the rails it slides on so you can put it back. Continue to slide it out until it’s free. Angle it down so the face sits on the towel you placed in Step 1.

Caution! Take care not to damage the orange fibre-optic cables by bending them too much. They are very sensitive to bends, and are made of glass, not flexible wire.

Step 4: Remove center console side trim screw.
    There are 2 panels you should take off in order to properly route & secure the cable.  First, on the right-hand side, locate the trim attachment screw. It is a cap with a hinge. You will have to move the seat full rear to allow access to screw.  Carefully pry the cap off to expose the screw head. Then remove the screw with the Torx screwdriver & place it somewhere safe.

Step 5: Remove two right side center console side trim panels.
Remove the forward panel by sliding it down slightly to come out from under the curved trim. Then, slide it rearwards. Using a combination of these movements, and keeping in mind the attachment points, slide the panel free & place somewhere safe.  The picture below shows the 3 attachment points.

Optional: For the rearward panel, move the seat full forward, release the 2 attachment points in the rear of the panel, & slide it backwards. Move the seat full rearward again.  You are now ready to route & connect the leads!

Step 8: Plug leads into EHU.
    The main connector must be disconnected in order to properly insert the terminals into the terminal block.  To do this, use your thumbs to open the lever-lock.  After a little force & a small pop, the handle will rotate outwards & cam the connection away from the EHU.  Eventually, the connector can be pulled free without further obstruction.  Do not worry about which way it went in, it will only go in one way.

Next, remove the blue terminal lock by simply pushing it outwards.  There are 2 blue locks.  Choose the middle one close to the fibre-optic cables as seen below.

Flip the connector so you can see the other side.  Prepare to insert the terminals into the 3 cavities.  This is where they will go.  Please note that the terminals should be inserted in a specific orientation.

The orientation of the terminal is such that the triangular indentation on the terminal faces the center slot.  The center slot is located between the thick black wire & the thick red/blue wire.  Push the wire in gently.  Once in it will snap.  Pull gently to ensure it has seated properly.  You should not be able to pull it out.

Step 9: Know how to remove the leads.
    If you ever wish to remove the leads, they can be removed easily.  Using an unfolded paperclip, push the terminal outwards slightly, and pull the lead out.  The triangular indentation is what is keeping it locked into place.

Step 10: Reassemble radio.
    Replace the blue terminal lock by sliding it in the groove.  It will go in only one way.  If sliding it in is extremely difficult (more difficult than removing it), then perhaps one of the terminals is inserted incorrectly.  Examine & redo if necessary.

      Replace the main EHU connector to the back of the EHU.  Line it up & close the lever to cam it closed.  The lever will snap into place indicating that it is home.

Step 11: Test your installation.
    Connect your handsfree device to the Tel1 EHU leads & test the operation.

     Alternatively, you can connect the Black lead to any bare metal part of the car and that should mute the stereo.  You can also connect a mono audio source (just left, or just right, or combined) to the red wire and signal ground to the Silver lead.  This is basically another Mono source in for your stereo.  Verify sound is coming out of left & right speakers by using the Balance control.

Step 12: Secure cable.
    Using included cable ties, secure the cable in a couple places so it does not wander, or rattle against the plastic trim pieces. Also remember to use the scissors to cut the excess length from the zipties.

CAUTION! Pay special attention to ensure cable will not interfere with operation of parking brake, if located nearby. If you choose to test the parking brake to see how it hits the cable, remember your car may roll as it is in Drive!

Step 13: Reassemble vehicle.
    This is pretty straightforward. First, while holding on to the 2 HVAC cords with one hand so they don’t disappear, use your other hand to slide the EHU back into the center stack. The bottom of the CD player should be right on top of the ashtray. It will get slightly harder to push the EHU in. This is due to tension form the 2 side clips. As long as the fibre-optic cable & other wires are not kinked, it is okay to continue pushing in until the clips snap & the unit’s front is flush with the sides & front edge of the ashtray.

Plug the HVAC in using the 2 cables you have in 1 hand. Extend maroon clip & place on the HVAC side. Push the maroon clip in. It will cam itself into place. Repeat for other side. Slide unit into center stack. It will slide in & snap quietly into place.  This illustration show the connectors properly connected.  Remember manual climate control will only have 1 plug.

Reinstall the plastic trim pieces. The rear one has 2 attachment points in the rear of the panel.  The pin goes in the slot, and the tab sits on the metal flat.  Line the forward hole up with the screw hole.  Like so:

The forward one has a guide leg to help you. Once the leg is engaged, and the top edge of the trim us under the top black fixed trim, slide forward until the screw holes match up.

After both pieces are in, align both panels with the screw hole, install the screw & snap the cover closed.

Step 14: Clean up.
    Remember your car is currently in Drive with the handbrake pulled. Turn key to "On", press brake pedal, shift into Park & pull key from ignition. Start car as normal (turn stereo on if necessary) & test the whole installation once again. Congratulations, you’re done!
