Why Did The Shop Do This? 2001 Tahoe, Viper 5706, DB3

Does your Tahoe have the Factory Alarm? What exact Viper model are you using? Anything connected to the Tahoe's Yellow Passlock2 wire? It might help if you listed all the actual connections.Soldering is fun!

Yes factory alarm Viper 5706v Passlock to db3 rap off output I can try to look for all the connections but might take me a while since I have to go through the diagrams and harness to make sure since they extended wires using pieces and also clipped wires I had already ranMr.562

"Passlock to db3 rap off output" ???   Thought the DB3 was removed.Soldering is fun!

The module was removed but they left all the harness attach including the one to the brake and obd 2. I think at this point I'm better off removing everything and starting all over again.Mr.562

If you do that, you should plan now on what type of Passlock2 bypass module to use. As you already found out, going with any type of module that requires a special firmware flash prior to use is a bad choice for DIY'ers. Too many hurdles to jump and issues to get around. There are a few "full featured" modules available that are ready to go right out of the box.   Of course these modules probably won't be able to handle the DBI D2D comm so they would be hardwired between the Viper and the bypass module. If you want to hardwire the door locks, etc, you could go with a basic Passlock2 module as mentioned above.   It would appear that is what you currently have from the local 12 Volt installer. Anyway, let me know what bypass module you plan to go with and I will either supply you with a wire chart or review the one you propose. (I did not find the earlier post you mentioned with that info that no one responded to.)Soldering is fun!

If you start with the key and then engage the RS does the vehicle remain running when you turn the key off?Steve G

When I start it with the key then use the rs the motor turns as if it was starting but also the starter keeps cranking as if it hasn't started.Mr.562

Please verify which color wire in the vehicle is connected to the Solid Pink Ignition 1 input/output wire from the Viper. I can not tell from the photo if it is connected to the vehicle Pink or White. Are you using tach or virtual? Has that been set properly in Menu 3? Is this an automatic transmission? I see a labeled wire for e-brake and I’m wondering what it is for? If automatic was this properly changed from default manual to automatic in Menu 3?Steve G

Pink to pink ign. Virtual tech I dont see no actual wire to either my cluster or ECM. The vechile is automaticMr.562

Is there any specific bypass modules you recommend besides the db3 from what I'm gathering calling this shops today that's what they are selling for the viper alarm. I will continue to call see if I can find another option. As off right now I will run the viper as alarm and the db3 as the bypass module hopefully this reflash I got done works and it all goes well apparently my local shops dont carry any other bypass or they just really wanna push the db3 out. So with no luck for other options I must proceed to get my vechile up and running this is how I presume the wiring should go. Mh.
