Using Relays for Window Roll-up!

Hello,

  I have a 94 explorer XLT and want to add window roll up, and window roll down to my existing alarm (omega/ 4-button remote). I want to use relays, instead of a module. Would I start with the wires coming from the driver door for all the windows, or do I have to do all doors seperate? How do I go about wiring these relays for up/down. I know how to do a drivers door priority relay configuration, would it be similar? Any help would be great!   Thanks,   Jeff

well, since you have such an abundance of relays and want to learn, you could build your own module by doing the following:

get yourself an amp meter capable of reading 0-20 amps.  connect it inline with your current window circuit and measure the current it uses when the window is going up and down..... then measure the current when the window is already up, and you try to roll it up (or it's already down and you roll it down) -- lets assume you already did that, and the free moving amperage of the window is about 12 amps - and the "bottom out" or blocked current draw is around 18 amps.   go to an auto parts store, and get yourself a couple of 15 amp auto-reset circuit breakers.  now, what you can do is something like this for each window (since i'm not sure just what you want your alarm to control, i'll have to assume you want them rolled up on lock, and i'll also assume your alarm has a momentary output circuit for door locks (which i wouldn't reccomend using for rolling the windows down, unless you have a two or more button remote, then you could use the trunk unlock button as the unlock/roll windows down function) - anyhow.... I'm also going to assume your alarm has a + when armed or a - when armed (for my example, i'm going to use a - when armed, but if your alarm has a + when armed, you can improvise by reversing polarity from the door lock input on the relay)  use the diagram below for each window to roll it up, you can improvise on it for rolling down, etc - you shouldn't have a problem with it -- just remember that your circuit breaker must be a couple of amps below the blocked current draw but at least the same or preferedly 1 or 2 amps above the unblocked current draw.  enjoy.
