Car Electronics Questions? Ask an Electronics Expert for Answers ASAP
there would be no "wire to wire" instructions, as it would depend on what you want your 4105 to do & how you want it to operate.I can supply a Vehicle Wiring Guide that shows the Color, Polarity & tells you the Location, but does NOT tell you how to take the vehicle apart to locate.IF you do NOT have the 4105 Installation Manual I can see IF I can post that alsowill that help?
I understand.........As you go thru the Viper wiring colors, you will have to compare them to the Ford Wiring Guide.IF you have the Remote Start wires connected, then you are 1/3 doneThe 1998 Expedition uses Negative Door Locks, but you should use "Relays" to Lock & Unlock, because the Viper does NOT supply a strong enough Ground (250ma)The 1998 Expedition uses PATS (passive anti theft system), which you will need a "ByPass" Module......be sure to get one that is D2D for the Viper (data 2 data)Other than that, you need to decide what else you want the Viper to do

Please understand..........I have been installing, Selling & repairing Electronics & Remote Starts for over 30 years.The Diagram I posted is more than enough information to Install the Viper.You have to compare each one of the Viper wiring to the Vehicle Wiring.There will be wires on the Viper that you will NOT useThere will be wires in the Wiring Guide that you will NOT use.IF you have NO experience in this type installation, It would best to have someone with experience there to help you or have a shop install.One wrong wire connection can cause damage to your vehicle.Sorry, I am sure that is not what you want to hear, but I have seen to many jobs that has cost the customer more $$$$ than letting someone with experience install
Let me know if you need further
o.k...........you did not tell me if you have any experience with Remote Start InstallationsI am assuming not, as the Installation is a "comparison" of the 2 diagrams & I am sure you did not know that the Door Locks require RelaysIF you need wiring diagram for the Negative Lock / Unlock Relays, please let me know
Are you still with me?
