window automation using just relays

So after weeks of trying to figure it out about a year ago, I decided to give another go today and see if I could get it to work this time. Well i finally got the relay system down 100%. I havent put it into the car yet (my wife's 06 Liberty), but I tested it using a DMM and with grounding the "aux 4" input I get a + 12volts on the meter, and with grounding the "aux 5" input i get - 12 volts. Which means that it should be ready to go. The only issue I still have is how to set it up so that it shuts off when the window is fully closed/open. Obviously with using the aux outputs, I can simply let go of the button, but as far as timing it goes, Im a litle stuck. I know that the DEI module uses a resistance "shut-off". Does anyone know how I can recipricate that??? Here is my diagram I came up with. I tried to make it as easy as possible, but with 8 relays, its not exacly easy to do. Let me know what you think. Thanks Kenny Edit: dont mind the additional switch/motor.. diodes dont work, so each additional window requires 2 extra relays. Also, when i rewired it following the diagram to double check it, I believe the diodes are reversed (cathode direction)Kenny

Most window closers use safety circuits such as thermal or load sensing as cut -outs or end stops; therefore it would be far safer to use one. Even here I would rather use` a 530t  at $75 than relays, 2 per window for up down.

PS your diodes are the wrong way round coming from the alarm at least.

the one I made i ended up using 5 451m's (adding 1 451m for the second window). due to the whole motor thing, I think I will end up going with the actual part, but I was quite happy with myself knowing that i was finally able to make it.. lolKenny

Did I read that right? So I will need four 530t's at $75 a piece for two windows?

No. 1 530t per 2 windows.
