2003 Silverado, Avital 4103 Remote Start w/GMDLBP

im wondering if anyone could possibly help me out with the wiring for an Avital 4103 remote start and a GMDLBP bypass. i found an awesome thread for a GMC yukon but it uses a different bypass kit, any help is appreciated.

W2W connections for 2003 Silverado w/Auto trans using GMDLBP bypass module and Avital 4103 R/S.

Programming :

The GMDLBP comes set to Type 1 platform.  You must change this to Type 4 for your truck.  See Page 4 of the installguide for the directions.1) To change the Vehicle Platform Setting, press and release the program button until the LED flash rate is the same as      the TYPE of vehicle required. The number of flashes from the LED confirms the Vehicle Platform Type that has been      selected. Ex: 1 flash = TYPE 1, 2 flashes = TYPE 2, and so on...EX: If TYPE 4 is required: Please note the module is already in Vehicle Platform TYPE 1. Press the programming button to advance to the next TYPE selection (3X times in total). The LED will then flash 4 times to confirm TYPE 4 selection.2) Once Vehicle Platform Type has been selected, press & hold program button until LED blinks once to confirm setting     is saved & ready to program to vehicle.3) Release programming button and the LED will come ON solid.4) Start the vehicle with the ignition key: The LED will turn off confirming the GMDLBP is programmed to the vehicle.

The Avital 4103 needs a few programming changes.

If you connected the Horn wire & want Horn Honk confirmations :   Menu 1, Item 1 to Opt 2If you want ignition controlled door locks - see Menu 1, Items 2 and 3It is best to run in Tach Mode.  Connect the Tach wire and set Menu 2, Item 1 to Opt 4.  You must also do the TachLearn process described in the 4103 install guide, Page 28.As listed above, to support the White IGN wire properly the Pink/White Ignition wire must be programmed to IGN.This is the default setting for Menu 2, Item 6.

Soldering is fun!

Thanks a lot for that info seems like a lot, but i think i can do it, first time doing a remote starter, but i guess i should start somewhere.   Bob

Plan on the whole week-end. It's not a 2 hour job.When all else fails, Read the Instructions

ya thats what i was thinking,im a little confused on this part:is this a relay i have to buy or is it part of the RS Extra 30/40 Amp SPDT relay for ACC2 circuit Relay Pin 85 to Avital 4103 Orange (-) Accessory Output Relay Pins 86 and 87 to Silverado RED / White +12V constant @ ignition switch harness with 25 Amp fuse Relay Pin 30 to Silverado Brown (+) Accessory2 wire @ ignition switch harness

It is an extra part that is not included in the Avital 4103 kit.  The truck has two Ignition wires and two Accessory wires.  The 4103 can only directly support 3 of those four circuits.  The relay with 5 wire harness is available "on-line" and at better auto stores.Soldering is fun!

ok i understand now thanks again   Bob

Sorry about this possible issue.  This wire should be connected to a solid metal , clean, rust & paint free frame location under the dash.
