power folding mirrors ls400

Hi I just purchased a set of power folding mirrors for my lexus ls400 with the JDM switch included but i dont have a control module to control the opening and closing of the mirrors so i need to make up a relay to control there opening and closing.

 The motors in the mirrors have two wires coming out of them and they work of reverse polarity. the button that came with the mirrors is a one press open one press closed design and has 4 wires coming out of the back of them.

 i would like to know how to test what each of the wires at the back of the button do and i would also like to know how to wire up the mirrors so that when you put the key in the ignition the mirrors open at the same time as the steering wheel droping into position and of course closing when the key is removed but i would also like to have the function of the button working aswell .

 From testing i have found that the mirrors keep turning if power is being constantly delivered to them so i will need some sort of timer to stop them moving after a certain point. i think i need to use a dpdt relay to control the mirrors when my key is put in the igntion but i dont know how to wire that up with the addition of the button and the timers so that the mirrors dont keep turning.

Sorry for being vague i dont have alot of experience with electronics can someone please help me out

Thanks for the reply. No there's no light in the switch, the button has no feeling to it , it doesnt stay depressed once it has been pressed or feel any different just clicks and pops up again with the same feeling ( but that is how it should feel )

I would get a control module but they are very rare and i would have to get it from japan.

your simple approach sounds very sensible so if i was to hold it down they would fold and if i was to release and then press again it would unfold? how would i go about wiring it up like that with the mirrors unfolding with the key in the ignition? thank you so much for your help

I dont think i made sense in my earlier post saying about how the steering wheel drops. with the lexus when you touch your key on the ignition switch the steering wheel drops down into the position that you set it to before you turned it off and i would like the steering wheel to drop down along with the folding mirrors unfolding

Thanks

On hondas aside from the control switch with the power folding mirrors there is a timed relay that accompanies it. This helps because the timing on opening an closing is perfect.Everything works moving a couple of wires around on the stock plug going into the mirror switch. I also connected the mirrors to the door locks and everytime I arm the vehicle the mirrors close and disarm the mirrors open. Of course I disabled the ignition controlled door lock/unlock feature on the Viper alarm that I dont like anyway. If no factory timed relay is available than the 528t is another option instead of two relays.
