2003 impala remote start issues

One more question. Does acc2 need to be connected? Im assuming I could trigger the relay with either the white or green thick wires from the 600s? What does acc2 run? Thanks

I believe the Brown ACC2 powers extraneous items like wipers and power windows, not too sure.  It shouldn't hurt

anything to try it without.  If you you want to power it, the CM600-s makes it pretty easy.  Use the thin WHITE/ Blackwire (-) Accessory Output to control the extra relay. 

Wire as follows :

Relay Pin 85 to CM600 WHITE/ BlackRelay Pin 86 and 87 to +12V constant thru 20 Amp fuseRelay Pin 30 to Brown ACC2Relay Pin 87A not used - insulate

Soldering is fun!

I agree with kreg357. I never power it, including on my own personal GM cars. This way, the wipers remain off during remote start, even if you left them on when you parked the car. P.S. Just curious, did the parking light input on the INTSL work for you? I tried it once a few years ago and it didn't.

Did a 2005 Trailblazer with an INT-SL recently.  Went W2W and it did control the Parking Lights through the INT-SL module.Soldering is fun!

Yes the parking lights work. I opted not to hook up the acc2. Everything works great now. The only thing that I would like is for the doors to auto lock during remote starting. I couldn't find this programming info in the owners manual, but that's not saying it isn't written somewhere. Thanks a million!

Not sure if the D2D mode will complicate things but...here is a possible ( indirect ) solution.Assuming you are not presently using the CM600-s Orange Rearm Output wire, take a look at programming option 2-07.  If you program 2-07 to Setting 3 and connect the Orange wire to the INT-SL Purple Lock Input wire, it should accomplish your needs.Soldering is fun!

Thanks! I Googled programming compustar 600s and found an installation manual. I bough 3 of these online and neither included this manual. I was going by the wiring listed on the rear of the 600s and the instructions that came with the INSTL+. No wonder I had a hard time lol. I assumed that since all 3 units did not include this manual that it only had a users manual? I appreciate all of your help!!!
