Any interest in P/W w/key off delay DIY?

[southpawboston]

if the fact that the mazda5 does not allow you to continue to operate your power windows for a period of time after you turn the key off irks you as much as it does me, then i *may* have a solution for you.

back when i had a mazda3, someone from the mazda3 forums designed a simple circuit to modify the power routing through the fuse box and incorporate a timed delay for power window operation after key off. i built a module, and it worked flawlessly on my mz3 for the four years i owned it. i had the module programmed to provide power to the windows for two minutes after the key is turned off. a nice touch on the design is that it did not involve any splicing or modification to the car. it simply replaced some of the fuses in the passenger compartment fuse box with modified fuses wired into a small module.

now i can not live without this feature. when i traded the mz3 in, i removed the module, reverting the car back to stock. i am planning to install it on my new mz5, but it won't be quite as plug-n-play, as the mz5 fuse box is quite different and some of the circuits that i need to tap into are in the engine compartment, not the passenger compartment. if it all works out, i will post the details and complete DIY here.

I used one of these for the dome light. It would work perfectly for this application also.

nice. very similar to what i used:

Wow, if that thing will do what it claims you can do some seriously heavy-duty stuff with it. I need that for my "evil toys" toy box.

The only thing that has me concerned about that, is that fact that it only works with up to 2A max.

I don't think you could roll up more than 1 window without exceeding it's output. This means it would require an external relay to achieve reliable integration. If that's the case, the 6062 is probably the better choice for this application.

you are correct, and i did indeed use the PAC with an external 30A relay. since the 6062 is rated for 8A, i would probably use an external 30A relay with it anyway, just for extra precaution. external relays cost less than a buck each, and they just about never fail.

the altronix is nice because it's cheaper and can do the same thing as the PAC. i may try it next time i need another timer module. interestingly, a simpler altronix module, which i just found googling around, is the 6030, which will still do a timed delay... can be bought for as little as $10.

Cheap is good!

I don't see how the 6030 would work because it's a delay ON timer. Timing starts when power is applied, then the relay energizes at the end of the timing cycle. TRG input only seems to be a reset or OFF without pulling power.

interesting... i didn't catch that.
