dei 530t dual switch

I have a vehicle and I would like to install 530T's for the windows but I would like to have the setup with two switches per window (complicated reasoning). Can I simply wire both switches in parallel or do I need to use Diodes to isolate them? If I need to diode isolate how can I determine the size of diode I need? The vehicle is a 1972 Chevrolet Chevelle

Series.

Sorry didn't explain too well*. Are you using regular window switches or just switching to ground to power the 530t? * I'm confused by your question and I rushed in with the wrong answer. I thought you meant "regular" window switching then wire in the 530t to the looms. In fact it doesn't matter HOW many switches if you are using switches to simply control the 530t trigger wires, the only place you would need diodes would be where you were joining from an alarm's aux output.

I will be using regular window switches. Basically ones mounted on the door for each window and then a set remote mounted to control all windows from the drivers seat

Look at this diagram, it shows one driver's door and one passenger. This is the standard type "A" wiring. The slave switch is in the passenger door and is wired in SERIES. Please read and follow the 530t instructions and wire as I've shown to the motor. This will give you one-touch up and down. 530t_wiring.bmp

I know how the a normal wiring setup would be as I have one installed on another car. I'm looking to have 2 switches per window both switches going through the input side of the 530T. So I can have 1 touch operation from both switches. I will try to put together a diagram later if I can but basically 4 power window motors all controlled by the 530T (2 of them) and 8 switches all going to the input side of the 530T's (2 per window) IE 8 switches for 4 windows.

Exactly and I showed you the wiring for one of them. Remember for one touch on all go directly to the motor.

I took a second look and I see what your saying now. So does the Master switch run through the slave or are they T'ed off? I'm just trying to understand how this works. I have attached a diagram to see if were on the same page (Yellow=White)

Yes but the 530t goes to the slave (right hand) outputs, not inputs.

Wouldn't this bypass the 530T on that second switch and only allow one touch on the switch that goes into the 530T?
