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 Lane

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

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 series
4X4'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.

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.

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 with

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.

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.

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

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.

Well i found another schematic of the message center the has the wit to start feature in it. the message center has a common ground that looks to feed the whole circuit board. So my best guess is that the wait to start is a positive wire on this truck.

Your best bet is to use the built in timing feature of the Viper. I had the same truck and it worked perfectly that way. You will also need to put a "five wire" relay pack in the drivers door. I installed two relays just under the handle. Worked like a charm until I sold the truck.

Thanks for the info, im actually wiring this right now. I have the 5 wire relay, it came with the remote start. Glad to know someone else has done this to this red headed step child of a truck.

Ok well its all hooked up. the only thing is it doesnt work, when i hit the remote start all i hear is relays clicking inside the Viper's brain.   
When i hit lock the light blinks on the Valet and when i hit lock it goes off, I didnt hook the locks up yet though because i ran out of daylight, so only the remote start is hooked up. Neutral safety switch is plugged in and in the on position, hood switch is not hooked up so its not grounded. Brake wire is good. Any thoughts?

You near Lafayette by chance ill give u a hand?

I am about 45 minutes north of Lafayette, Demotte/Wheatfield area

If you want pm me your phone number you can come down and ill help you get it sorted out

If you have a meter and are good with it see if you are getting voltage on ignition wire from remote start unit

I will do that. it will have to wait until this weekend when I get some free time. Maybe i can get five minutes to check

I've figured it out! Lol i had the dang thing in manual mode! and its an automatic. Once I figured out that the lights were flashing 7 or 8 times and looked up what it meant I changed it over lol. Thanks for all the help you guys have given me on the adventure.

Now if someone could give me some directions in simple terms on how to program the wait to start timer I'd be the happiest man in the world lol

Anyone? I've searched the forums and Google repeatedly and have turned up nothing. I've followed the direction but must be doing something wrong

Anybody?
