Saab 9≥ 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
youíre going to break a clip, stop, reread the instructions, perhaps
interpret them differently, then try again. If that still doesnít 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.
Tools youíll need to complete this installation:
Etadyne recommends using the Removal Tool from Saab, part# 8293474
-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.
Prepare a work area.
Step 2: Remove & unplug HVAC faceplate.
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.
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 itís 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.
Step 5: Remove two right side center console side
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.
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.
Step 10: Reassemble radio.
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.
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.
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.
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.
