Here are the specifics:
Vehicle: 2015 Jeep Wrangler w/ OEM Alarm
Unit: Fortin EVO-CHRT5 w/ Flash Link
Programming: Everything is set to off, with the exception of C1 - Send Lock/Unlock, D1 - Stand Alone Remote Starter, D1.6 - 15min runtime, D2 - Unlock Before / Lock After to diasble OEM Alarm
Symptoms: Unit installed per instruction set C (stand alone). Press lock 3 times triggers start, engine turns over, starts and immediatly shuts off. Saw from another Q/A that I should try connecting the GWR (Ground while running) wire. Tried this and all of the electronics went haywire when trying to start (radio, dash lights, etc.). I'm now stuck - not sure what to try next.
