how to keep a relay energized ?

I'm looking to keep the coil on a relay energized with a momentary positive switch.

I'm using the (+) pulse from the arm/lock wire to send a pulse to a relay for the window roll up module(#85 pos pulse from lock, #86+87 to neg from alarm ground when armed and #30 to neg input of window module)

. I tried using the ground when armed wiRED / but it sends ground as soon as the ignition is switched off which immediately rolls up the windows. (not desirable)

So I need a diagram that will keep the relay's coil energized for 10 seconds from the door locks .8 second positive pulse.

(does this make any sense?)

Using an autopage rf-310.

I tried tapping into the wire that goes conected to the starter kill relay, (ground when armed)  that's when I was getting an apparent ground that triggered the window roll up module.
