DIY Cruise Control FAQ (2006-2010 Yaris)

[cicici00]

I have been really busy and did not have any chance to install my cruise control since I bought my OEM stalk from ebay (like months ago). I finally find a weekend to do this thing. I just want to make sure I get the set-up right before I break into my car.

I have a 2008 LB Yaris.

1. I first cut off the red+black wire clip at the end of the stalk

2. I see the "Spiral Connector Repair Terminals" in the parts requirement. I wonder if I really need it, if I treat the stalk = diy switch/button. Can I hook it up like in Fig. 1?


3. I think I will get "ECM repair terminal" for Pin 40. I know CTScott sells them. Since I finally find a free weekend to do it, I need that part sooner. So, I wonder if I can buy that from Toyota Dealership and get it on the same day? Or can I just get one from the junk yard? Or if Advanced Auto / Auto zone / radioshack sell them?? I am just afraid if I don't do it this weekend, it will be months after I can do it again.

4. I thought about just insert the wire into Pin 40. But, I am scared it will not be secured. How far do I need to insert the wire into the A21 ECM? Does the ECM terminal has some clip to hold all the wires in place? Anyone here did it without the "repair pin"??

Thanks again for all the help!!

1/2. You don't really want to clip the connector. If you are planning on mounting the stalk in the steering wheel, then it needs to go through the spiral cable.

3. If you want to use the pins, I can ship them today via priority mail for $5 more (bringing the total to $15 for the three pins), so you would have them in hand before the weekend. I believe that the dealer price on them is $12 each, so you would still be saving quite a bit, and I don't think that dealers typically stock them.

4. People have done it this way, but it does not always make good connection and is not sealed, so it will allow moisture to enter the connector.
