Wow!! This is an impressive thread. I have read it front to back a couple times and still don't have this figured out. One more full read should do the trick.......I hope.
My current, and very simple take away is this, and PLEASE let me know if I'm off base!!! *****I am skipping over all of the complexity in the wiring and color changes. I will go back and study this carefully before getting started.
Locks:
The master switch panel requires the addition of two relays , one up and one down. 14guage wire should be used. I'm still not clear if there is a definitive way to maintain the window lock function???
Windows:
All four doors need to have 14guage grounding wire run to the chassis. And two relays wired into the switches of all four doors. These switches now only activate the relays. So the master switch panel only needs relays added for the drivers door. The two relays added to the other three doors will now be activated by both switches, the one in each door and the switch in the master switch panel.
Both mods will require 10 relays. 2 for the locks, and 8 for the windows. Is this an accurate big picture description so far???
I did a third read through of this entire thread as planned. My simple summary is NOT correct. Both mods only require 8 relays. The drivers door does not have relays added for the window mod, as this door has relays inside the door already. The BIG GREEN BOX, as is explained two or three times with the 12 pages of posts. This now makes much more since to me. Adding 4 relays to the drivers door would be A LOT.
After editing my original summary, this is now my plan of action,
Door Lock Mod.
1) I'm going to add two relays, one up and one down to the hiring harness side of the door lock, which will allow me to secure the relays with ease, and then simply plug the master panel switch into the OEM connectors as always.
Window Mod.
1) I plan to run new 14guage ground wires to all three passenger doors though the door grommet, to a clean grounding point under the dash. This will be simple as I am already in the process of inspecting , repairing, and rewrapping the factory wiring harness. I will be able to fold in the three new ground leads to the factory loom. I have inspected the positive leads to each door. The original positive wiring is in good shape, so I do not plan to run a new positive lead wire to each door.
2) I will add two relays to all three passenger doors , splicing into the door switch as described in this thread.
3) I have been applying standard grease to the power window mechanical assembly in each door, thinking this would help improve their functionality. This was a mistake as it turns out standard standard grease gets sticky and slows down the motion of the window. So I will take each unit out of all four doors, clean them in great detail, and apply white lithium grease to the moving mechanical components.
This is a link to the relays I will be using.
Any notes, please shout out. Otherwise, I'll catch ya'll on the flip side with an update after installing both mod's.
