Wiring on SDStudios Pulse Rifle?

Does anyone have any detailed pictures of how the SD Studios Pulse rifle was wired? Specifically the trigger. I have seen the pictures on Phil Steinschneider's page, but they are kind of small and hard to make out. I know that the battery is housed in the magazine with contacts at the front, top. and a delrin block with contacts is connected to the upper reciever (have on one order from SD). It's mainly the trigger wiring that I'm interested in. I am planning on wiring mine up in this fashion, so any help would be appreciated.

Thanks.
 
Since he was the one who made it, did you ask Steve how it was wired or if he has any pics you could use?
 
I just use a standard, heavy-duty lever switch. You will need to grind off a bit from each side to fit into the cavity.

The wires will have to be routed through a trough cut into the top of the Thompson grip frame with a Dremel. I glue them in as well. Leave plenty of wire. You can always cut it later. But if it is too short, you have to start over (or splice). These two wires go to the count-down contacts on the board.

Just MAKE SURE that the switch clears the moving bolt above it BEFORE you final-glue it into place, or on the first pull you will smack the switch into oblivion.
 
Steve,

Thanks for the info. Would you happen to have any pictures of how you fit the switch into the trigger group?
 
Taking a look at my thompson parts and the pictures from Phil's site, it looks you removed a couple of parts from the trigger group to make room for the switch. Is this correct?

Edit:

I just took mine apart and removed these parts:

Which left me with the trigger group looking like this (sorry about the flash):

Sorry, I don't have any pics. I have removed several non-critical parts from the trigger group, but you don't NEED to do that. The lever switch will fit right on top of the trigger in the open area, no problem.
 
No problem. I have removed a few parts and I think I see how it will fit together.

Thanks for the help. Looking forward to getting the parts I ordered from you.
