93 dodge cummins remote start

Hello everyone. I'm new to the forum and new to installing remote start on vehicles. I'm pretty proficient in wiring and reading schematics so this shouldnt be an issue, however, I have a 5101 Viper remote start and I want to pair it with my 93 Dodge D250 Cummins Turbo Diesel. I have all of the Dodges wiring diagrams and the Viper install sheet. I'm just confused on what wires in the remote start harness i dont need and exactly what ones need to be hooked up and to where. I have power door locks that I'd like to have wired to the Viper system as well. Any help or information is greatly appreciated. Thank you in advance, Travis Lane1

Anyone? I can provide the Viper Install sheet if it would help?1

I will give it a go.  But there are some variations on the Viper models and their harnesses.  I'm not positive I have the

correct listing for your truck.  I assuming a D250 is a rear wheel drive ( 4X2 ) Ram pickup ( as opposed to the W series4X4's ).  Obviously, you will want to verify all this info with a DMM.

Soldering is fun!

This is precisely what i was looking for. Thank you so much. I have the diesel tach provision wire, Grey/Light Blue. and yes the D250 Ram is just a 2WD and the W250 is the 4x4. Let me ask this, the harnesses that have no wires to hook to, do i still have to plug those into the remote start module? Its a dumb question I know. And I'm sure i know the answer to it already.1

Used to have a 1977 W150 Power Wagon. 

No such thing as a dumb question.    Yes, if a harness has no needed wires, leave it off.  Unused wires in a harness can be cut to 2" and bundled neatly or even de-pinned / removed.  Keeping the install neat is important.

Do you have any info on a Wait-To-Start wire?  That could work better than a fixed 15 second delay.

Soldering is fun!

Yes i do, the wait-to-start wire is Dark GREEN / WHITE. DO i just hook the Grey/Black directly to this wire? It says something about a resistor in the install sheet that came with1

The Viper is looking for a (-) input signal on it's WTS wire.  Depending on the vehicle brand ( Ford, Dodge, GM ) and the engine, the WTS signal type varies.  Sometimes a diode is also necessary.  Follow the install sheet, but if it does work properly you can always use a fixed time delay. Soldering is fun!

Excellent, thank you for all your help. I will be tackling this this weekend. I appreciate everything and I'll let you know how it goes.1

here is the schematic of the wait to start circuit. I'm not sure if its positive or negative?1

Can't tell from the diagram.  The sure way would be to put a DMM on the wire and see what happens during a start-up.  Maybe another forum member has prior experience with this model truck and can help out.Soldering is fun!
