Battlefield 4 schematics are as followed: connection (1) goes to RB & connection (2) goes to LS.
COD Ghost schematics are: connection (1) goes to "B" & (2) goes to "A".
Veiw the schematics below for instillations. Pic #4 shows the proper connection to solder the led to. View all other pics for button and trigger locations.
Veiw pic#3 for alternative positive power sourse. If u look across to the left from the LS connection u will see a test point #9 or (TP9) on the board. This is much easier to use when mounting your chip or chips to the backside of the board.
Pic#5 shows a good spot to wire your ground pin to.
If u decide to do a dual chip setup wire pins 1,2,3,5 & 8 together on both 12f1822 microchips. From there just run 1 wire from any of the two chips to the solder locations on the controller PCB board following the schematics on pic#1 & 3. All that's left is running the wires from pins 6 & 7 (labeled button connections as (1) & (2) in the schematic print pic#1) to the button locations specified for the individual hex code the chip was programmed for. Then u will have to hook up two 6×6×7 mm tactical buttons (spst) from both microchips.
I'll update more when I get a chance. I'll post codes to members only through PM and a drop box link. I'll post my mod roster here shortly. They will both now be 10 modes each.

The akimbos and burst shot codes I've made can be used on both chip as far as programming goes. The quickscopes unfortunately have to be coded to the BF4 chips. This is why its best to do a dual chip setup. So much more benefits + being able to run 2 modes at once. A lot of my codes already run multiple mods at once. This will give u all a idea of what I have to offer.
Let's just say u tell me what modes u want in what order or a specific rapid fire speed u want and I'll custom make u a hex around your settings up to 10 modes for each individual chip.  
  
Here are pics for the dual chip setup. In this pic u will take your two flashed chips then cut the legs short on your microchip. Remember to label what chip is what, be that a sticker or something other.
Here is a pic of the chips being solderd together by pins 1 & 8. Make sure the chip is flipped on the other chip correctly where the same pins line up.
Here is a pic of pins # 2 & 3 being linked together.
Here is a pic of pins#5 being linked together.
Now all u have to do is run one wire from the linked chips to the board connections power, ground, led, LT & RT. Then connect pins 6 & 7 to the locations based off my schematics for the individual chip, ex( BF4 chip (1) goes to RB (2) goes to LS; Ghost chip (1) goes to B (2) goes to A) this is based off the schematic in pic#1 at the top of the thread.
U will also need to wire 2 tac switches to run each individual chip. I'll update where to mount the chip or chips and a operations guide at a later time.
