04 jeep grand cherokee parking lights

I have installed a viper 5101 remote start and a DEI XK531 transponder / lock control bypass. My issue: I can't find a way to make my parking lights stay constant when in remote start mode if the light switch is in the automatic mode. However I can send a negative to the flasher relay and cause them to flash, this I cant stand nor my neighbors. Currently I have a negative pulse with a 1300ohm resitor running to the yellow wire at light switch. This provides constant lights on ONLY when light switch in off position (So no auto Lights on while driving) I have attached a wire to the parking light relay pin 30 and get the same effect. Anyone know how I can keep the switch in the auto on light position and turn my lights on during remote start mode? Thanks in advance! jc

Did you isolate the switch with the WHITE/ brown wire? If not, Cut the wire in half, connect your white wire to switch side and the WHITE/ brown wire to the other side. Put your resistance in the negative fuse spot and fuse the line elsewhere.

I am confused as to what wire I am suppose to connect the non switch side? I am using a viper 5101 so my white wire has adjustable polarity via a fuse link under a cover on the unit, so i only Have one wire from the viper unit. What is the function of the WHITE/ brown wire. I am assuming it is in the harness at the column with the yellow parking light wire and the blue/pink flasher wire?jc

The yellow parking light wire(on vehicle) needs to be cut - connect the WHITE/ brown(from Viper) to the switch side of the cut wire, and the white(from Viper) to the side facing away from the switch. The purpose of the WHITE/ brown is specifically for controlling the parking lights on Chrysler products with resistance switching parking light circuits. On these vehicles, like your Jeep, instead of having a switch which directly powers the parking/head/fog lights, the switch sends a negative-through-varying-resistors signal to the Body Control Module, which then activates the lights. Basically, when the Viper is not activating the parking lights, the switch on the vehicle functions normally. When the Viper activates the parking lights, it cuts off the resistance signal from the switch and tells the BCM to turn the parking lights only on.C Renner's Auto Electronix

After reading through the forum I found a tech tip from autocommand that requires breaking off pin 84a relay. I did do this so will i need to replace that relay?jc

Sorry I meant 87a. chriswallace187 you where exactly right everything functions fine now. I did have to replace the relay with one that had a 87a pin. Thanks for your help!jc

Excellent...glad to hear it!C Renner's Auto Electronix

Sorry to resurrect an old post, but I am looking to accomplish the same thing on my 2002 Grand Cherokee with Auto headlights. However, I have a compustar 6200 brain and it does not have the equivalent (to my knowledge) of the BROWN / white wire on the Viper. Is there a way I can leave the lights set to auto and have only the parking lights come on during remote start with the compustar? Thanks, Jason

lilngineer, Yes, it's doable. You just have to use a separate relay controlled by the parking lights wire from the brain. I'm not sure exactly what parking light outputs that Compustar model has, but here's 2 ways of wiring the relay. First, if you have a positive parking light output: 86: positive light flash output from alarm 85: ground 87: ground, with a 1300 ohm resistor wired inline. Also as I always recommend, cut a piece of cable tie and tape it lengthwise along your resistor connection to help prevent the resistor from breaking. 87a: cut the yellow multiplex lights wire and connect this pin to the side facing towards the light switch. 30: yellow lights mux wire, side facing away from the switch. If you only have a negative light output from the Compustar: 87, 87a, and 30 are connected the same way as above. 86: 12 volt constant fused 85: negative light flash output from alarmC Renner's Auto Electronix

Chris, Thanks for the help. My compustar has both negative and positive triggers. Compustar sent me a Fortin diagram that showed the positive trigger setup you mentioned, however on the diagram it says that the parking lights will not work in the auto setting. Do you know if this is true?
