locating txct and code wire

Hi, I am trying to install an Autopage 665 2way and an idatalink ids-tbsl-ko on a 2006 Sienna and I am having trouble locating the TXCT and Code wire on the car. I've downloaded the manual off of the idatalink site and it said the wire should be "yellow" for Code on a 4 pin plug and Yellow/Red for TXCT on a 5 pin plug but I can not locate these wires. The only wire that looks like yellow/red is on a yellow plug on the bottom of the steering wheel and I figure that might be for the airbag. Am I wrong? Any help would be greatly appreciated. Thanks.

I think you are confused, the wires are in a 7 pin plug, pins 4 and 5. It will be under the ignition switch and have the light around it in the same module. Not all Siennas had immobilizers in 2006, the base model did not. The easy way to tell is to look for a security light next to the radio, no light = no immobilizer...Mike M2

The seven pin connector should be at / on the igntion switch itself.   The colors are correct and Pin 3 should be empty.  While all the Sienna's in that model range ( 2004 - 2007 ) that I have done had the immobilizer, it is possible that your van does not have one.  Have you tried a remote start without the bypass module?

Stay away from that Yellow plug / connector, it's probably the airbag...

Soldering is fun!

Haha, thank you guys for your quick reply. Yea, I was a little confused when posted last. I do remember seeing the picture of a 7 pin plug on the idatalink information sheet, but I could not locate a similar 7 pin plug anywhere, so I assumed it was 4 and 5 pin plugs. It is already 2230 here, so I've already wrapped everything up. I will double check to see if it is equipped with an immobilizer and also try to remote start without the by pass module once I have some time to work on it again. I will keep you guys posted on the status. Once again, thank you.

Sorry, I don't mean to double post, but I can't edit for now. Mike, I am using the diagram you posted for the 2006 Sienna to do my install and was wondering if there is a way to verify the blue wire for the door trigger. I tried testing for voltage by opening and closing the door but the meter screen just stays the same. Thanks.

You are using the blue wire on the dome light switch? It is the only one on the switch. Sometimes it is easier to test on voltage instead of ohms. Try putting your meter on voltage, it will read 12volts closed, nothing open.Mike M2

TX and RX: Look at the keyhole where you put the ignition key. There's an illuminated ring around it. Put your hands around the black plastic part that houses the illuminated ring and follow it deeper into the dash. The connector with your TX/RX should be plugged in there. If you unplug it and try starting the car, it'll just crank and not start. From there you just have to find pins 4 and 5. Note that Pin 3 is empty; this will help you know which end is #7 and which end is #1. Door trigger: If you're using the domelight wire, the domelight takes a LONG time to go out after closing the door. Instead of waiting forever, insert the key and turn the ignition on. Now you'll notice that the domelight goes out right away when you close the door, so you don't have to wait while you're testing the wire. NOTE: You're already going to the ignition cylinder for TX and RX. The illuminated ring around the key cylinder catches all five doors. All you have to do is test the wires there and find out which is the negative light-ring-trigger wire. NOTE 2: The illumination ring is powered separately from the dome lights, and is not a high-power circuit. If in the future you decide to add more domelights to your car, don't tap in at the illumination ring.

Thank you everyone for the replies. I found the 7 pin plug containing the txct and code wire. I've been hooking everything else by looking from the bottom up and was not able to find the plug. I got in the car today and look straight down at the key cylinder and found the plug. The door trigger on the dome switch has one and only one blue wire and it is the one I probed. I also did set the meter on voltage. I decided to just use go with that blue wire and hooked up the last few wires, programmed idatalink, program my tach signal, and then the car started up remotely. But there are a few things I need to look into further. 1. The driver door did not trigger the alarm when I first test it by arming the system and then sticking my hand in to unlock the door and open it. So, I ignored it for a moment and went to check the other doors. When I flip the unlock toggle on the door handle on all the other doors there is a ~2 seconds delay and then the alarm triggers. I then went back to the driver door and it is also triggers now. 2. Second thing I need to look at, and this could be the actual module and or the alarm disabling it, is that the remote starts works fine for a few times and then it wouldn't start the system. I would hit start on the remote, get an "ign" icon as feedback saying it's trying to start and then it would beep twice and not start. In between the time it works and it stopped working I've set off the alarm severytimes testing it. I also got remote start to work again after several cycles of arm and disarm. 3. This was the last thing I worried about but I think I f*ed up good. The parking lights didn't come on when it started remotely even though I've connected the Parking Light Output of the remote start module to the GREEN/ Black wire on the headlight switch. So...I started the car remotely and flip the parking lights on and the car shuts off. After that the module didn't respond to any command from the remote. I checked all the fuses and it's still good. The system won't arm, disarm, or remote start. The blue light inside isn't blinking any more. I unplugged all the wires and reconnected it and still not working. I opened the brain up but didn't smell or see any burnt mark. Could I have fried anything inside? I'm pretty sure all my connections are good, but I will double check tomorrow or when I get a chance. Please help or tell me what I'm doing wrong. Thank you. BTW, this is my second install. The first one was a similar module, autopage 603 with just remote start, on a 2001 camry and everything is working fine. For those interested, the rear defogger wire is the YELLOW /GREEN wire behind the defogger switch.

Your first problem really isn't a problem, since you used the dome light feed for the door switch, the delay will cause the doors to only trigger once the dome light extinguishes completely, and also trigger a few seconds after you open the door, since the light does not come one right away when u do, so no problem there. commit your way to jehovah and he will act in your behalf. psalms 37:5

Thanks t&t tech. I will try the suggestion Chris Luongo gave when I get a chance.
