2005 gmc denali 535t install

Just a quick question. Can i interface both the 535T's for all 4 doors at the master switch in the driver door? Or do i have to go to each door individually? Also, if i remember correctly i have to use relays for these Type C wire window motors, correct? Thanks in advance

Both front doors have window wires only inside the doors. I think you can get the rear-door wires inside the car somewhere.

Do relays have to be used with the 535t's for this type C system? Or can i connect directly do the 535t?

bump, does any one know if relays MUST be used for this vehicle (2005 GMC Yukon Denali) for the 535T's? The window motors are type C. Also, i would like to use the Ground when armed wire to roll up the windows, however this is also a remote start. I have read i will not be able to roll the windows down while the remote start is engaged since it is always supplying a ground during the remote start sequence, correct? What other output on the viper 5301 can i use that will allow windows vent/roll down while using the remote starter is enganged and being able to keep the anti grind relay enabled? Can i use the -500ma lock output with comfort closure to still have the windows roll up upon pressing the lock button? Please let me know what the best way to achieve this is? Thank you in advance im using a idatalink ads-alca bypass module.
