Two DEI 535T Window Modules

Hi Forum, I have 2 x 535T (one for front and one for rear windows) - looking to hookup with the Viper system and all good so far but I am a little lost on the connection. ( I get the purpose is to stagger power draw for window rollup) This is the operation flow I seek: WINDOWS ROLL UP PAUSE ON REMOTE START 535T FRONT WINDOWS ROLL UP FIRST , THEN 535T REAR WINDOWS ROLL UP IfI hookup the H2/5 from the front 535 to H3/4 on the rear 535 and this will stagger window roll-up. how is the starter (-) integrated into this ? (I would think this would create a loop of sorts?) - SEE DIAGRAM SKETCH (if so which way do I orientate the Diode?) H2/5 GRAY: (-) 500 mA Output during activation Connect this wire to an optional relay to bypass sensors which may trigger the security system during operation of the 535T or connect to the Gray/Black (-) delay of a secondary 535T to have the windows stagger when closing. This wire continues to output (-) ground for 5 seconds after the window motors have stopped. H3/4 GRAY/BLACK: (-) Delay input This wire will prevent the 535T from moving the windows as long as it is receiving a ground. Once the ground is removed, the 535T will begin to move the windows.
