Power window module ?

Ok here's what I think

for the first question, no you don't need a relay simply hook your output to your input since both are ground signals

Second you don't need a relay for that because power window modules already have built-in relays just hook it up as the diagram says

Third, the power window module acts as a bypass allowing you to still use your windows under normal conditions so don't worry they'll still work normal if you install it right

good luck!

Ok I believe this is a window roll up module. So for this you'll use the armed signal from the alarm usually the same armed signal used for the starter kill so when you arm the system the windows will go up. Normally window roll up modules have an armed input, armed output, so you need to cut the armed signal wire from the alarm and connect the input and the output from the window module.  otherwise if you don't split it your windows will roll up when you turn the ignition off or on. I don't know if this makes sense to you it's kind of late but this is how it works. Or you can save all of that and just hook up the window module like the diagram says, and use a channel from the alarm to activate the window module.

good luck any other ? let me know

What you need to do is find an activation wire that outputs 500ma ( either continuous, latched or 4-6 second pulsed ). This is what the window modules do:

• When activated through the activation wire, the module will operate as long as there is a pulsed (-) signal.
• If you hook up a 1 second pulsed output, the window module will only operate for 1 second ( keep in mind that SOME window modules only require a pulsed output while other require an output long enough to close the window )
• Now, it doesn't matter if you have a constant output on this wire because the internal voltage sensor will detect a voltage spike when the window is closed or open all the way. The module will automatically cut power off to the windows and it will not drain your battery at all
