I wand to hook up the remote starter relays that you show a diagram of in the Special Applications with SPDT Relays

Can you please run down the install for me?

I see how to wire the relays but what do I hook it up to on a alarm? Accessories line? I want to start it with the alarm remote.

And also on a car with no alarm what should it go to?

Thanks

El Sandman

If you don't have a good amount of wiring and install knowledge, I would not suggest tryng to use this remote start. You would be much better off with a commercial microprocessor controlled remote start. They have many more features, will be simpler to install, and much quicker with less risk.

Hi El Sandman, that is a remote start I created from relays years ago. A few things it doesn't show are additional features I've added to it so it could be controlled by a single pulse to start and stop it, a timer to shut it down after a predetermined amount of time, the additional relay needed to shut it down when the brake is pressed, and any additional devices necessary to bypass any anti-theft system you may have in your vehicle. I drew it and added it to my site only to show what can be done with relays, however with the price of the current models available today and the additional features they include, I'd strongly recommend using a commercial aftermarket unit as NyxBass suggested for these reasons and more.

BTW, as the diagram is above, yes, it works. The leads to connect to activate it are shown as "(-) trigger to activate remote start" and to shut it down "(-) trigger to deactivate remote start". You can use an output from your alarm or keyless entry or even a momentary contact switch to provide a ground pulse to either lead. All other leads are clearly marked. If you are confident with relays and in your installation abilities, then you should be able to figure out how to make it work in your vehicle, but I do not offer any assistance installing this. Don't take it the wrong way, but as it's been stated many times before, using an aftermarket unit is the best way to go. It will cost you less in the long run for the features they include and take you a lot less time to install. Although I've built and installed several of these, and most are still in use today, I still prefer to only install aftermarket units.

Good luck and let us know how you make out.
