Viper 4104, 2012 Toyota Tacoma

Hello all, I've just installed a Viper 4104 in a 2012 Toyota Tacoma. Not sure if I'm missing something obvious or what, but the only thing that is working is the panic feature. No light flash. No horn honk. No door lock/unlock. I can't even get an led flash on the control center. Any ideas? Please help! Thanks

Perhaps if you listed your Viper to vehicle wire connections we could get a better idea of what is going on.Soldering is fun!

Sorry Main 6pin harness: Red - WHITE/ red Black - ground Brown - GREEN/ red Wh/br - green Door lock 3pin: Blue - gray Green - blue/white R/S 8pin: Pink - WHITE/ blue RED / wh - wh/blue Orange - wh/green Violet - GREEN/ black Red - wh/blue Pink/wh - BLACK/ red RED / black - wh/bl Aux 24pin BLACK/ wh - ground Brown - blue Violet/ wh - BLACK/ wh

I unplugged the remote start harness, and now all the keyless entry functions work correctly including horn, lights, and locks.

R/S 8pin:

For the Starter2 circuit you will need a 30/40 Amp SPDT relay with fuse

Relay Pin 85 to Viper thin Violet (-) 200mA Starter OutputRelay Pins 86 and 87 to +12V constant ( WHITE/ Red ) through 20 Amp fuseRelay Pin 30 to BLACK/ White

Bypass module?

Ok, thanks. I'll try that tonight. Why would I need a bypass module? Thanks

Does your ignition key have a transponder chip?  Most do.  Look for a dot ( . ) or a G stamped on the top of the blade.  If you have a transponder chip, the engine won't be able to remote start.  You can test for a chip by wrapping the key head in several ( 4 or 5 ) layers of aluminum foil and the trying to start the truck.Soldering is fun!

Yes, I picked up a DBALL2 for the bypass. If I use this module, do I still need the relay for starter2? And, if so, why would relay pin 30 go to blk/wh? Thanks

The DB-ALL2 bypass module only handles the transponder bypass function.  You will still need an external relay

to power the BLACK/ White Starter2 wire during a remote start.  According to my info, here are your ignition wires :Ignition1 = BLACK/ RedIgnition2 = Blue / YELLOWStarter1 = GREEN/ BlackStarter2 = BLACK/ WhiteAccessory = WHITE/ Green

Pin 30 is the relay output wire that supplies +12V to the vehicles Starter2 wire.  More info on relays can be found here :

Did they flash the DB-ALL2 with the correct firmware for your truck?
