Non-diesel RS into diesel vehicle?

My lovely wife bought me a DesignTech 20092 Remote start today, it was on sale for $40..  While I know it's not the best, the vehicle it's going on isn't either - 1998 Dodge Ram 3500 diesel.

My question is..  using some sort of timer-type module, do you think it would be possible to have it wait the 10 seconds after the ignition is activated, fo the grid heaters can finish doing their thing?

There's a wire (parking brake light) that wants to see ground before it will allow a start.. perhaps a 10-second delay could be put on this?  Though, I'd hate to go through the hassle of installing the whole thing just to find out it won't work (perhaps the system would just cancel the whole start request if it didn't see that ground?)

Any ideas are welcome, and thanks in advance..

Yes, if it doesn't see the ground on that wire it will cancel the entire start process, so that won't work. There is no way to add any kind of delay on the start for the glow plugs..the unit has to be designed with some type of "wait to start" feature or it won't work.

What I would do is contact the manufacturer and see if there is a way to program it for that, otherwise you will need to use another system or live with it trying to start the truck too early.

The DEI 528T Pulse Timer Relay is an adjustable timer-controlled 30-amp SPDT relay (Single Pole Double Throw). The timer is adjustable from 1 – 90 seconds. You can activate the DEI 528T with either a (+) trigger input or with a (-) trigger input. The DEI 528T will provide a temporary circuit "connect or disconnect" and can be used in many applications. The DEI 528T can provide either a (+) or a (-) temporary output. The DEI 528T can temporarily disconnect either a (+) or a (-) circuit. The DEI 528T Pulse timer Relay provides complete flexibility whenever you need to temporarily either connect or disconnect any circuit (+ or -) with either a (+ or -) trigger input.

Im NOT a DEI guy...but why would this not work?

That DEI 528 piece is one of my favorites..it allows me to do almost anything. I guess it would be possible but in this case he needs this to happen..

you could use another negative output of the RS and have it pulse the timer, send an output of the timer to a relay to activate the ignition switch..hence heating the glow plugs for a length of time,

You would then need to press the remote again after the plugs are ready to perform the start. Now although this should theoretically work, it is a slight inconvenience and if you forget to hit the start in time you may need to repete the whole process again.

I really can't think of a better way to do this but if the sytem has a neg input hardwire for start I guess you could have a second timer activate the RS start after a length of time as well but now it's getting more expensive. I still reccomend a unit with a built in "wait to start" but regardeless, almost anything is "possible"..it's just a matter of how much work, time, money and head scratching you want to do to make a cheaper unit perform like a slightly more expensive unit will do out of the box.

This is for when using it with a unit that already has a "wait to start" feature. It is a timesaver if it is difficult to get to the "wait to start" light, you could program the unit "DEI has this feature" to wait a programmable lenth of time before it engages the remote start funtion. During this time the timer would do as I stated in the last post and power up the ignition circuit first. However, since he states the designtech does not have any kind of wait to start for deisel it would need to be done the way I stated.

I still would double check the instal manual for any way to delay it, or with the manufacturer. If there is none you only have the options posted.

"This product has many popular uses by installers of mobile electronics. Some examples include: creating a wait tostart trigger for remote starting diesel vehicles that do not have wait to start triggers."

This can be used if the VEHICLE does not have a wait to start....or has I posted it has one but it is difficult to access. It is another way to have the delay but the RS unit still needs a wait to start feature.

In other words without a wait to start feature on the unit itself the timer of course can be used to heat the plugs but it won't actually wait to start this way. It actually won't start at all without pressing the remote again AFTER the pulgs heat.

No sweat Car TuneMan, that info is not useless at all. If more people knew about this pulse timer and how to use it that can only be a good thing.

I have been using them for years and they are extremely handy and I think they retail under 30 bucks. Now most of the newer high line DEI systems have built in programmable timers but for other brands or entry level systems that do not, it's use is virtually endless.

However, I guess you understand why in this case it is not really a "cure all" but it can be done theoretically.
