Here are the questions that I have:
1. I cannot find the Rx and Tx wires for the Bypass. Does my car even need the bypass? How do I know if my key even has a chip in it? 2. How do I know if my car has a factory alarm? If it does, where are all of those wires located? 3. Before hooking up the remote start, all doors would lock but just the drivers door would unlock. Can I hook up something differently so all doors unlock at the same time? 4. Do you need to hook up any of the "satellite harness" wires that are all (-) 200 mA status, accessory, starter, ignition outputs? 5.Do you need to hook up any of the following (if so, where to): (-) 200 mA factory alarm disarm (-) 200 mA factory alarm rearm (+) ignition our (to alarm) (-) activation input 6. There are two BLACK / YELLOW wires running down from the ignition switch. What do I do with the one that I did not use? Thank you in advance for any help you can offer. I am baffled!! ------------- just another car guy Replies: Posted By: kreg357 Date Posted: June 21, 2015 at 3:51 PM An easy way to determine if your key has a transponder chip and you need a bypass module, is to do the foil wrap test. It is described You can program the Viper to a double Unlock pulse output ( Menu 1, Feature 5, Option 2 ) to unlock all the doors with one Viper Unlock Your car probably doesn't have a Factory Alarm. To test, get in the car, press the lock button on the drivers door while the door is open, If you have the transponder based engine immobilizer system, you will need the (-) 200 mA Status Output wire, if you don't go D2D to One BLACK / YELLOW wire is Starter 2 and the other is IGN 2. You will need to use a Digital Multi Meter to determine the difference. That is Here is a link to the Wire Guide from ReadyRemote : https://www.readyremote.com/main.asp?make=Toyota&model=Camry They even have a photo of the main ignition connector for wire identification. Bulldog Security has the wire info for your car along with a bunch of photos.

First of all thank you for all of the information that you provided. I found out that my car does not have an alarm, nor does it have a transponder system. That is the good news. The bad is that I still do not have the remote start working. Here are a few more questions: 1. Does relay pin 30 (satellite harness starter output) go to the same BLACK / YELLOW (+) (20 gauge) wire that the pink/white goes to? 2. If so, that is how I have it hooked up. 3. Here is what it does: I hit the remote start button and the chime goes "ding". The lights on the dash light up. The radio comes on and all sounds good for a brief second. Then the radio goes out and everything sounds like it is powering down. 4. Any idea why, before and after the remote start install, only the driver's door unlocks??? Any more help would be great!!!!!!! ------------- just another car guy Posted By: kreg357 Date Posted: June 22, 2015 at 7:29 PM Not sure of your question. Here is the install : There are two thick Red wires in the Vipers main ignition harness. Both or these get soldered to the WHITE/ Red +12 Volt constant wire Going by the photo, just to the right of the RED / White wire is a BLACK/ White wire. This is Pin 8 and the Starter1 wire. The Vipers thick Again, going by the photo, just to the left of the WHITE/ Red wire is a BLACK/ Red wire. This is Pin 6 and the Ignition 1 wire. As shown That does it for the top row. On the bottom row, the unique wire is the Blue/Red wire. ReadyRemote lists this wire as the Accessory That means that the Black Yellow wire just to the left of the Blue/Red wire is Pin 4 and the Ignition 2 wire. The Viper's thick Pink/White All that is left is the BLACK / YELLOW wire that must be at Pin 1 and marked as Starter 2 by all the available wiring guides. The Viper is Reference #1 ReadyRemote wire guide Reference #2 Bulldog Security photo Reference #3 Viper main ignition wiring Reference #4 Starter 2 relay ------------- Soldering is fun! Posted By: kreg357 Date Posted: June 22, 2015 at 7:33 PM There are a few programming changes the Viper needs and you must do the Tach Learn process.

It works!! I did not have the relay hooked to the correct BLACK / YELLOW wire. You have just made me the greatest Dad on earth. I would not have been able to do this without you. You are truly an amazing person, with kindness and patience that we all wish we had. Thank you again for sharing your knowledge and allowing me to witness a smile on my son's face that would provoke a tear or two in any man's eyes. ------------- just another car guy |
