Viper 4105v, Flashlogic FLCAN, 2004 Chevrolet Silverado 1500

Can anyone give me insight into this setup. I got the setup as a Christmas gift from my wife. It also includes a 8617 relay. This is my first attempt at a remote start. I’ve tried doing some research but I’m still kinda stumped on where to start exactly and show the remote start and bypass tie into each other. I am both mechanically and electronically competent. Just not on GM vehicles, more so aircraft. I have the wiring diagrams for both units and a wiring list for my truck. Any insight or help to get started would greatly be appreciated.Kyle D Mack

https://www.the12volt.com/installbay/forum_posts.asp?tid=133000 for a pictorial. The FLCAN has multiple ways of interfacing with the remote start module. Do you know if the FLCAN was 'flashed'? That will determine its wiring requirements.

How would I know if it’s flashed? It was bought from crutchfield. I looked at that thread. Still having trouble wrapping my head around some of it. For example the hardwire vs data mode. How are the wires from the bypass to the remote start connecting? Depinning those were and soldering them together? Things like that.... I’m just trying to make sense of it all and find a solid place to start from.Kyle D Mack

May have to contact Crutchfield, ask if they flash them...maybe shows on the receipt. If flashed as hardwire, physical connections between the remote start and bypass need to be performed. if flashed as data, there's an interconnecting cable between the two modules, less connections between the two. Connections between the two modules can be done by soldering yes...or even crimp connectors/crimp caps.

Ok I got this all wired up thanks to kreg357, and it works like a champ, but now I’ve noticed some type of battery draw while the truck is off. If it sits for more that 24 hrs I have to jump it off. Are there any common occurrences with remote start systems and this issue?Kyle D Mack

I'm curious, do you have anything connected to the ground-while-armed wire?My ex once told me I have a perfect face for radio.

I do not. I was instructed that the FLCAN would handle this function. I have the black wire from the 9pin harness and the black/white wire from the 5 pin harness of the viper connected to ground.Kyle D Mack

Pull the fuse(s) for the Viper/FLCAN for 24 hours and see if your need to jump it go away. That or use an amp meter to find out how much amps it's pulling at rest.

Out of curiosity, did you add a relay to power the second accessory wire? If so, how did you wire the relay? Lectric Guy

I did install the second relay.
