Installing RS on A 1998 Blazer. Auto Command. Does this vehicle have a 3rd Ign.? Vehicle starts and runs for 10 seconds, works fine with key. Troubleshoot code says vehicle was shifted into gear. I used resistors to bypass Passlock 2. The 3rd I gn wire from the RS module I hooked up to the relay is a ground output. Should this 3rd ignition power a relay first ? Thanks !

Did you use this diagram to bypass the passkey 2? https://www.the12volt.com/installbay/file.asp?ID=250
You may want to use a "ground output when running" or "status output" wire to power your relays, it comes on BEFORE the ignition outputs.
