upgrade from viper 560xv to 5901

Hello all, This is my first alarm /remote start installation I've started, even though I'm able to read schematics and wiring diagrams that I have had to deal with, I'm having some difficulty understanding exactly which wire from the 5901 has to be connected to the appropriate wire in my 2004 F150 xlt. I've managed so far to have successfully connected the alarm using some of the existing wiring connections from the 560xv, my small dilemma is understanding the wiring for the remote start and whether or not I have to use the existing relay that's part of the circuit operation of the 560xv. I would sincerely appreciate any suggestions /information that will help me to successfully complete this do it myself project. Sorry for the lengthy post.Learning is unending and as such the knowledge acquired. Vic

Sincere thanks tedmond for the input, I have the bypass that was used with the previous system its a 566S specific to the F150; I don't have a wiring diagram for the truck but I have the schematic (text that states wire color and voltages, not all voltages; /use) that's what I've used so far and was able to get the security part of the 5901 functioning. I'm going to try to do the RS hookup as you've pointed out (12v, acc,etc.) Question; Do I need any relays or diodes or it's just to connect correctly that remains?Learning is unending and as such the knowledge acquired.

you might require a few diodes for door triggers, but other than that i think you are ok. you may also need an extra relay for what reason it may be (ie defrost, etc)

Thanks tedmond, will let you know how it all turns out.Learning is unending and as such the knowledge acquired. Vic

I've been running like crazy; finally got back to the install I hooked up all the needed wires (as far as I can see) however the RS isn't functioning, I get a code which represents "Manual trans mode, not initialized" my ride is automatic I also checked the setting of the 5901's brain (shows automatic) someone told me the bypass module I'm using is the cause (it's module specific for F150, hmmm?) any suggestions? The security feature is still working great distance and all.Learning is unending and as such the knowledge acquired. Vic

You need to program it to the automatic setting, factory default is manual!commit your way to jehovah and he will act in your behalf. psalms 37:5

The viper 5901 is not at default setting of "Manual" it has been switched to "Automatic" so I guess I'm overlooking something else. I plan to clear all module memory and start configuration from the ground up, to see if I can find what step I may have overlooked.

Hello again, attempt to remote start "The lights flash, I hear relay(s) energize but no cranking of the engine" the system tries about 3 times and then I get remote start error displayed in the lc3 transmitter, however there are no flashing lights (diagnostic code(s))being displayed. Any suggestions anyone?Learning is unending and as such the knowledge acquired. Vic

Sounds like a bypass issue! Try disconnecting the bypass, and insert the key in the ignition barrel and leave in the off position and attempt a remote start and post back with results!commit your way to jehovah and he will act in your behalf. psalms 37:5
