'02 monte carlo remote start issues

I don't want to bring up an older thread, but I did want to post as to the resolution of my situation. I ended up purchasing a PLJX, and my problems were fixed! The system remote starts with no problem, and the wiring for the bypass was relatively simple. I wired in the door lock/unlock harness with resistor, as well as the relay for the (-) trunk release. There is a note on the wiring diagram from the Bulldog Security website that states: "NOTE *3 An extra Relay part #775 is needed for the (-)Negative Parking Light Isolation Circuit on this vehicle." Could someone explain to me the necessity of this? Out of curiosity, I wired in the the remote starter directly to the parking light wire at the BCM, and it seems to me that everything works just fine; the lights flash as confirmation of a signal received. Thanks again for the help, it's been WAY more helpful than the questionable at best quality of service I've received from Bulldog.

Apparently there's sometimes a problem if that white (-) parking lights wire from the BCM sees a ground and the light switch is not sending the "parking lights on" signal - this could cause the "service vehicle" message. If you don't have this problem, it's nothing to worry about. If that message does come on, I would suggest just cutting that white wire, inserting a diode with the striped side towards the BCM, and connecting the output from your remote starter on the non-striped side.C Renner's Auto Electronix

My service is cheap, quick, and good - pick any two

I see, thanks for clearing that up. I do now have a SES light, but I attributed it to multiple starts and shutdowns, without really letting the engine warm up. Before I begin cutting and soldering, I'll pull the codes and see if it is in fact referencing an issue with the parking lights or if it's something else. This site is a wealth of information, and I doubt I could have gotten everything installed without it! Thanks again to everyone!
