Since Vinster03XR brought it up, here is a "how to" using what I learned from everyone here. All credit is due to the prior posters in this thread http://matrixowners....opic=56433&st=0 . Thanks to Tigger, hammy233, Squashtowner, tcmatrix, river1, mariagwyn, losmorob, angusmcoz, tman_00, camryvibe, and anyone else I might have left out.
These pics are from my install on my 2006 Matrix base model with a 5-speed tranny.
1st up, you might want to see if you have Drive By Wire. That's easy, look underneath your dash to see if it matches this pic.
If you have that, what follows should be all you need.
0. Pre-install. Write down all your radio presets and any head unit sound settings because you will be disconnecting the negative cable to your car battery. DISCONNECT THE NEGATIVE CABLE FROM YOUR CAR BATTERY!! Thank you.
1. Parts: Cruise control switch assembly and clutch switch (clutch switch not needed on the automatic transmission Matrix). I got the cruise control from http://www.rockauto.com/ and the clutch switch from http://www.discounttoyotaparts.com/ .
Cruise Control Assembly part number: AC Delco D1919E
Clutch Switch part number: Toyota 88280-14030 (If needed)
2. Airbag removal part a. Remove the T30 Torx screws that hold the airbag assembly to the steering wheel. Note: Even with the screws loose, they might not be free from the airbag assembly. I had to slightly pry open the rear steering wheel cover by the airbag assembly to knock the screws clear with a small thin screwdriver. (See new photos later in this thread!)
3. Airbag removal part b. Remove the airbag assembly or lay on top of the steering column. Use rags to protect the steering column from the airbag screws. Remove the green wired horn ground at the plug and ground tab. Save for later use.
4. Wire swap part a. The green horn ground wire must be moved to the new cruise control assembly plug. Start by removing the white wire locks on both plugs.
5. Wire swap part b. To remove the green wire from its plug, take a very tiny strong wire (like a re-shaped staple) and push into the tiny hole directly above the small hole that the green wire is in. With a little finesse, the staple will release the green wire terminal lock and let the green wire slip out of its plug undamaged.
To be continued.......
