2003 saturn vue dei remote start

hello, im trying to install dei python 1400xp on my wife car , after reading all posts and possible info on web i know less and less. few questions , please help: 1.where on DEI product do i hook up keysense wire from car , do i need relay , do i hook it up to (-)200mA 2nd status/rear defogger- latched/pulsed , or somewhere else 2. do i need any relays when connecting to ignition harness? 3. how can i connect rear defroster to box to be started by AUX button on remote? do i need relay or just have to find wire on BCM ( witch one ) what output do i use on box ? 4. please direct me to schematic of connecting diodes for door opening . do i need it only for door opening or closing too? doncz

Do you have a DMM to test your wires with?? A soldering Gun?? Scotch  Super 33+ tape??

You are going to need a bypass module.

Thanks, I know this , but still need, answer for my questions Any help please , im realy confused with keysense wireing and door trigering with diodes. Sombody told me I need relay for accesories doncz

NOTE *1 THE LIGHT GREEN(-) KEY SENSE WIRE AT THE STEERING COLUMN MUST SEE A (-)NEGATIVE DURING REMOTE START TO KEEP THE SERVICE ENGINE LIGHT FROM COMING ON. THIS WIRE IS ALSO FOUND IN PIN A11, GRAY 24-PIN PLUG, @ BCM.

NOTE *3 THE DRIVER DOOR TRIGGER IS GRAY/BLACK (-) IN PIN B2. THE PASSENGER DOOR TRIGGER IS BLACK/ WHITE (-) IN PIN A12. WHEN CONNECTING TO AN ALARM SYSTEM USE BOTH DOOR TRIGGER WIRES AND DIODE ISOLATE, TO CONNECT, SEE DIAGRAM.

The above info is from the bulldog site. There is a diagram of diode isolation of the doors for your car.

I think the python 1400 is the same as the viper 571. You shouldn't need any relays for the starter, ignition, or accessory wires.

What brand od bypass are you using?

I used 556lw , it is working fine. Problem is that im mot familiar eith description of outputs on DEI unit, This is why I dont know where to hook up keysense, or rear defroster control. Need some detail info for my car , not generic one. Thanks for any helpdoncz

To me it looks like the keysense would go to the blue wire on the  remote start auxiliary harness wiring.

I DID CONNECT BLUE/WHITE WIRE FROM BYPASS MODULE TO THIS OUTPUT ON DEI REMOTE BOX still looking for wire to connect keysense . doncz

I found solution for key sense , im going to use same output as for bypass module separated with diode. still looking for info about wireing rear defroster.doncz

For some reason I remember the Saturn's key sense wire needing an output stronger than what the 200ma output of the DEI unit can provide. I would suggest using the pink (-) 200ma ignition output to trigger a relay as follows: 86 - constant 12 volts. 85 - pink 87 - ground 30 - key sense wire of car DEI's tech sheet does not list the wire color/location or polarity of the rear defrost wire. A quick google search didn't help either. Most wiring sheets back then didn't list the rear defrost wire, and they haven't been updated since then. An installer would have to test the wires at the switch until they found the correct one. This would involve removing the dash panel it is mounted to, and then using your Meter to find the wire that changes polarity when the button is pushed. Most rear defrost wires rest at 12v, then go to ground when the button is pushed. Sometimes it is a quick ground pulse then it goes back to 12v. You will then have to make sure the output you are using from the remote start has the correct output (pulsed or latched). Some Saturns have a switch that "lock in" when you push the button. If you leave the button "On" when you shut the car off at night, it will automatically turn on when you remote start the car in the morning. May be easier than worrying about finding the correct wire and possibly frying a circuit in the heater controls if you mess something up resulting in a high repair bill.

(Wires located at the Defroster connector)~It's me!
