1 year ago I installed a Viper 4706 RS into my son's 2003 Silverado ss with a Fortin INT SL+ bypass module (service number 002102 074369). Works great. I bought an identical (red-not blue) 2003. I am installing a 5706V RS and alarm with same bypass (service number002102 091815).
Followed the exact same wiring install. When I try RS, it turns over but does not run. I have tried changing Tach sense from virtual (bypass module orang/black to RS violet /white pin 12) to wired (white behind instument panel to violet /white). Both cases the module does not light on command and the dash security light stays lit. If I remove the module and program it into my son's truck it works fine. It acts like it programs fine in my truck (light comes on, flashes after you turn the key, start with key, then light goes out.)
Called Fortin tech support and they said I had to have Firmware 0.53 flashed. The INT sl+ worked fine on the 1st install so I bought it again just so I would not have to flash it. No install shop near me is interested in flashing it. So now I'm questioning my install.
