Digital Touch Entry System Conversion

Ive been looking thru the FSM at the GXE keyless entry system, tons of other pages as well, theft warning system, the tcu, window switch, etc. I also have a VE SE in my driveway, and a digital dash GXE in my garage. After 2 days of crosschecking things in the fsm, and on the cars, I have somewhat of a start for a conversion write-up, there are only 2 or 3 wires im unsure of so I thought id post this up and see if I can get any helpful information..

when thinking of doing this conversion, I would only use one keypad/beeper in the driver door, and forget about the passenger side keypad

things you need
DIGITAL TOUCH ENTRY SYSTEM CONTROL UNIT w 2 harnesses
KEYPAD w harness
BEEPER w harness
KEY-IN SWITCH w harness
TRUNK LID OPENER RELAY w harness

HARNESS 1 (LARGER) AT CONTROL UNIT

TRUNK LID OPENER RELAY

white/red needs to go to w/r (trunk pop?)

3 of the wires that go to the CONTROL UNIT, also pass thru what seems to be some kind of diode box at joint connector 8 and 9. ORANGE/BLACK in HARNESS1 and BROWN and GREY/LAVENDER in HARNESS2. here is the schematic of that box.

sorry its so small

the ORANGE/BLACK (wire going to digital touch control unit, bottom half of the picture) also goes to the DOOR IDIOT LIGHT in the instrument harness, so I figure if I tap it from there to the control unit if will have the right kind of signal since its already thru the 'diode box'

the other 2 wires come from the driver window switch (they are door lock/door unlock wires), thru the diode box, then to the control unit

so far the SE has all the wires needed except for the brown wire in the window switch (SE door harness has 6 wires for the driver window, GXE has 9)

this diode box is somewhere around where the HUD goes and I dont have access to it to see if the wires are there in the SE...im gonna guess they arent...wondering if someone more electrically inclined knows more about this 'diode box?' im hoping i can run the 2 wires from the window switch straight to the control box (bypassing the diode box), but maybe ill have to add in some diodes of my own or something?

btw if no one looks at this or responds my feelings wont be hurt
