Does anyone have the wiring info on a 2001 impala? Reason I'm asking is because the wiring sheet I have says, for remote start I must relay isolate the park light wire from the BCM to avoid the SERVICE ENGINE SOON from coming on. What is relay isolate? I know what diode isolate is. I'm going to install a Commander 7000 which has the alarm & remote start, also I was wondering which bypass to use the 555t or 555L? Could I use the 456G for the locks & dome supervision to save some time or is that for certain GM vehicles. Is there a similar product like 456G for GM, that Ford, Chysler, & Mazda make? I have done quite a few of these remote starts with alarms but not on this particular car. Thanks in advance if anyone can help on these question?
