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

2001 chevy tahoe 5706 viper Db3 bypass module shop took over installation since I didnt get any feedback on my original thread regarding the wiring schematic I had laid out hoping to get sum feed back after this pic of what the shop did to my tahoe and get to fix it. Quick run down they eliminated the Db3 added 3 relays use tape and butchered my wiring after I had solder, shrink wrapped, and tesa tape my harness.Mr.562

I believe that this write up by kreg357 is the only thing close to my tahoe viper and module except that I run negative MH 5 connection. 2002 Silverado with Viper 5806 and DB-ALL2 flashed with 4.02 GM5 Ver 3.12.106a firmware. Assumptions : Gasoline engine, factory door locks, going with D2D between Viper & DB-ALL2. There is no need for the 451M door lock module, the DB-ALL2 will handle the locks and alarm via it's connection to the J1850 Data wire at the OBD2 connector.           Pin Color          Description     Destination MH   1 Red      (+)12VDC Constant Input      Red (+) @ ignition harness MH   2 Black             (-) Chassis Ground      Chassis Ground MH   3 Brown            (+) Siren Output       Viper siren MH   4 WHITE/ Brown     Parking light isolation        Not Used MH   5 White             Parking light output BCM Gray Connector, Brown wire, pin 6 (+)     * Set jumper to (+) MH   6 Orange          (-)500mA Ground when armed        Not used DL   1 Blue (-)500mA Unlock output            Not used - handled via D2D DL   2 EMPTY DL   3 Green (-)500mA Lock output Not used - handled via D2D RS   1 NC RS   2 RED / Black   (+) Fused 12V acc/start input          RED / White (+) @ ignition harness RS   3 Pink/Black (+) Flex relay input 87a key side     Not used RS   4 Pink/White (+) Ignition 2/flex relay output        White (+) @ ignition harness RS   5 Red   (+) Fused 12V Ignition 1 Input      Red (+) @ ignition harness RS   6 Green   (+) Starter Input (key side)       Yellow (+) @ ignition harness     cut wire RS   7 Violet   (+)Start output (car side)           Yellow (+) @ ignition harness     cut wire RS   8 Orange       (+) Accessory output          Orange (+) @ ignition harness RS   9 RED / White (+) Fused 12V Ignition 2     RED / White (+) @ ignition harness RS 10 Pink (+) Ignition 1 Input/output Pink (+) @ ignition harness AST   1 Pink/White   (-) 200mA Ignition 2/flex Output           not used AST   2 Blue/White   (-) 200mA 2nd Status/rear defog output          not used AST   3 RED / White    (-) 200mA trunk release output not used AST   4 BLACK / YELLOW   (-) 200mA dome light output              not used AST   5 Dark Blue    (-) 200mA status output           Not used - handled via D2D AST   6 WHITE/ Black   (-) 200mA AUX 3 output        not used AST   7 WHITE/ Violet   (-) 200mA AUX 1 output        not used AST   8 ORANGE / Black   (-) 200mA AUX 4 output      not used AST   9 Gray (-) Hood pin input (NC or NO)             to kit supplied hood pin AST   10 Blue (-) trunk pin/instant trigger input (NC or NO)      not used AST   11 WHITE/ Blue   Activation Input        not used AST   12 Violet/White   Tachometer input Not used - handled via D2D AST   13 BLACK/ White   (-) neutral safety/parking brake input            Not used - handled via D2D ( E-Brake ? ) AST   14 GREEN/ Black   (-) 200mA Factory alarm disarm output       Not used - handled via D2D AST   15 Green (-) Door input        Not used - handled via D2D AST   16 BROWN / Black   (-) 200mA horn honk output optional ( already have Viper siren ) AST   17 Pink (-) 200mA Ignition 1 output     not used AST   18 Violet (+) Door input           not used AST   19 Violet/Black   (-) 200mA AUX 2 output      not used AST   20 Brown (+) Brake shutdown input    White (+) @ brake pedal switch AST   21 Violet / YELLOW   (-) 200mA starter output    not used AST   22 Gray/Black   (-) Diesel wait to start input not used AST   23 Orange (-) 200mA accessory output       to extra relay Pin 85 ( for Brown ACC2 wire ) AST   24 GREEN / WHITE   (-) 200mA factory alarm arm output Not used - handled via D2D DB-ALL2 D2D harness to Viper Blue 14 Pin Plug Pin 2 Violet / YELLOW to OBD2 Pin 2 Violet Red 12 Pin Plug Pin 1 BLACK/ White to Tan (-) @ BCM, purple plug, pin B4 Pins 8 & 9 to Yellow Passlock2 wire at steering column harness Black 10 Pin Plug Pin 8 Violet to Viper     RS   Pin 7 thick Violet (+) Start output Pin 9 Pink to Viper       RS   Pin 10 thick Pink (+) Ignition 1 Input/output Extra relay ( 8617 ) for ACC2 : Pin 85 to Viper    AST   Pin 23 Orange (-) 200mA accessory output Pin 86 and 87 to Red (+) @ ignition harness through 25 amp fuse Pin 30 to Brown ACC2 @ ignition harness Pin 87a not used The DB-ALL2 must be flashed with the above specified firmware. Here is a link to the install guide : http://www.xpresskit.com/DocumentDownload.aspx?documentid=9294&productid=553&firmwareid=6501 Follow the Type 4 diagram / instructions. You will need an XKLoader2 cable to flash the DB-ALL2. There will be some programming changes necessary for the Viper. Things like Transmission Type, Engine Checking, etc. Mr.562

OMG. It's work like that that gives the 12 Volt industry a bad reputation. First question. Does it work? ( the pre-question is why did you bring it to someone? I'm sorry you didn't get a reply from you original post.    I don't use Directed products and after their recent purge, don't answer too many questions due to lack of    current knowledge of their products. ) Even if your Tahoe has a Factory Alarm system, you really don't need a full featured bypass module like the DB-ALLx series. Sure, they make things easier but a simple Passlock2 bypass module is all you need. And that appears to be what the install shop did. They used the old school "Relay and Resistor" method to bypass the Passlock2 during R/S. The other two relays are used convert the Vipers (-) Door Lock outputs to a (+) signal that the Tahoe needs, one for Lock and the other for Unlock. Don't know what to tell you. I would be very hesitant to bring it back to that shop. If it didn't work properly, I would ask for a refund. If it works properly, I'd be tempted to clean up the install, getting rid of the crimp connectors, soldering and heat shrinking everything, etc, making it neat and call it a day. Remember that the removed curved metal plate has some unfinished edges on it, so make sure the harnesses are well protected in that area. Soldering is fun!

I already had wired up using solder, heat shrink, and Tesa tape all that needed was the programming according to the flashes from the module it wasnt communicating and after reading that this modules dont take on the first try I assumed it needed to be reflashed with the proper software called around only shop that would reprogram it for me. It locks and unlocks but it doesn't start the tahoe, cranks but doesnt engage. Relays have no resistors from what I see and no they was not payed since they decided to do that work without contacting me and advance they butchered wires that were solder and they left wires without no protection (bare wires).Mr.562

Check the instrument cluster to see if the "Security" light is on during R/S cranking. That would indicate that the Passlock2 is not being bypassed and preventing fuel from getting to the engine.Soldering is fun!

Can't see the wires all that well, but it looks like the Yellow Passlock2 wire has something connected to it. Guess that the 3rd relay was for the Brown ACC2 wire. If that's the case, you will need a bypass module for the Passlock2 being as the DB-ALL3 is removed. If you trust the Viper alarm system to protect the Tahoe, you could do a permanent bypass on the Passlock2 or get a Fortin Passlock SL2 or a Directed 556 LW bypass module.Soldering is fun!

When I use the key it starts up fine when I use the rs it just cranks three times and then everything and the cluster goes dark (no lights).Mr.562

Any "Security" light on the instrument cluster during R/S crank attempts?Soldering is fun!

Seems that they connected the orange from Rs to my brown ignition harness the black/white rap off to my passlock and no it doesnt show security it does show my battery when I start using the Rs.Mr.562
