we are trying to see what it would cost just to add the mosfets to the board instead of a second board. Looking around $130 with them added to the board but that means you will have to run anywhere from 4 to 12 wires from wherever you locate the module to the drivers door switches, the sunroof switch and the keyless entry module.

Easiest would be to mount control board in the drivers door to keep all the window motor wires short, then remote mount two relays for the sunroof. Then you would only need to run two wires to the sunroof relays, and two wires to the keyless entry module.
That should keep it affordable too.

We can probably design the board with everything on it then when you order yours you can ask for all the add-on components and we'll just add them onto it.
Each of these mosfets is probably no more thatn $2-$3 so you would need ten or more of them to do every window, hense the $130 versus the $100-$110 range without them.

Sorry about the instruction manual, I'll fix it later or I'll email it out. It will be the old manual but I can update it for the new features if this group buy takes off.

To make it worthwhile I need a minimum of 6 at $110 or 12 at $100 since the boards are made in groups with enough mosfets to run the sunroof included. Sor for those of you who just want sunroof control there will be no additional costs for relays.
If we do anthing less than 6, like 3-4 then we might consider doing it for $120 each since we will still have to order boards that we can't sell in the first batch. This cost is without the mosfets added for the power windows, only the moonroof. We add those on as an additional fee, up to that $130 that I described before.

So here it is:

<6 = $120
6-11 = $110
12+ = $100

*I reserve the right to either continue or cancel the process if we don't get at least 6 buyers.
