Connect the red USB 5v from the SE motherboard to Cthulhu’s VCC screw in. V1 to red USB 5v to the Imp board. Make sure your wires GO THROUGH the holes when soldering on the SE PCB. When I first soldered my TE board, the wires didn’t go through the holes so I couldn’t power the board, once I solder the wires through the holes, then everything was fine.
I keep hoping that Faux123 will answer you because he has a better understanding of the electrical connections than I do. 
You should have a wire going from the 5V screw in on the Cthulhu to the VCC point on the SE PCB. (Or the point that Faux suggested.) I’m sure I tell you to do that in the guide…
You don’t have to use the Ground point that’s next to the VCC point if you don’t want to. All of the Ground points on the SE PCB do the same thing.
Edit: And there he is!
Hello,
Me and a friend successfully completed this mod about two weeks ago, and so far it’s been going without a hitch, but last night on two occasions the stick just stopped functioning. I had to restart the system for it to work again. However, when the stick stopped responding the power wasn’t shut off, because the guide LED was still on. Does anyone know what could be the problem? I DID duct tape the cthulu and imp to the board, and I made sure they were separate when I opened it back up, but they were kind of loose. Would the duct tape be a problem?
That was before. 
Having the weirdest problem with my stick right now. My joystick will not register on my 360. I can turn on my 360 using the guide button on my stick, and the LEDs around it all turn on, won’t flash, then turn off, and the stick is not registered on the 360. Anybody got any hints as to what be causing this?
Note: I did this mod with a DPDT switch.
You should’ve let me touch it with my voodoo magic at AR last night.
It was a 360 base stick? It could be any number of things, worst case scenario the security chip on your madkatz board died… Try plugging it into your computer on the xbox setting?
lol. Yeah, it was the SE with a Cthulhu dual modded in. I’ll probably try that tonight.
Doesn’t bomberman’s guide say V1 goes to VCC on the imp? I am confused. My V1 goes to the VCC hole on the imp, I dont know what I am doing wrong then?
Here is my confusion, aren’t you guys contradicting yourselves? VCC and 5v USB on the SE/TE stick are two different points. Right here Bomberman you tell me to connect the VCC SE point to the Cthulhu 5v screw in. yet here:
Faux Tells me to put the USB 5v to the Cthulu VCC/5v.
edit: I just looked at Faux’s picture and he has resistors by the USB ONLY parts of the cthulhu (the two red and two black ones) that I do not have. Are those only neccessary for the Multiconsole cthulhus, or am I missing parts maybe? :sad:
For connecting 5v to the imp from the cthulhu MC, is there any reason why I can’t use the row 2 or 3 column V on the cthulhu? I am going to add a PS2 controller and I’ve planned everything out so it will be very tidy, and would prefer not to have to solder 2 wires to the same point (row 1 column v).
Can you some photos of your setup right now? Sometimes it is difficult to figure out what people meant on-line.
You don’t need to solder 2 wires to the same point. Feel free to use row 2. Row 3’s the one that doesn’t have a diode protecting it.
Row three should have a glass diode.
thats tight i would try it but id might mess it up.
Whoops… Okay, what is row 3 lacking again?
Is there only one 5V connection point on the MadCatz SE/TE PCB? I see solder point labeled 5V and I see a USBVCC that is ribbon cable and much easier to access. For connecting just a regular Cthulhu pcb, can I use the USBVCC point to connect to the Cthulhu?
Edit: I used the USBVCC and it works great.
Are the start and select joints on Faux’s diagram labeled wrong? or is that how you’re supposed to wire them?
Back, Start (360 TE) to Start, Select (Cthulhu), respectively.
OR is it supposed to be
Back, Start (360 TE) to Select, Start (Cthulhu), respectively?
the latter would seem the logical choice, and I shall go with my gut feeling on this one.
Thanks though, this thread helped big time.
Salutations.
TE 360 + Cthulhu + Imp = Dual-Mod
I just wrapped up the soldering, plugged it into the ps3, to find out it’s not working.
I read through the forums, and am noticing some details about powering the imp etc.
To clarify, a few people mentioned connecting the V column Row 1 to the Imp’s VCC (as in Faux’s diagrams) works fine on an MC Cthulhu.
What about a regular Cthulhu?
Toodles also mentioned that if you desolder the V1 connection, strip the end, and screw it in the VCC screw terminal ( I already have a wire in there per Faux’s diagram) that it would power the imp. I’m lost, is that what I’m supposed to do here? Please clarify.
Help appreciated. Thanks!
Like Airthrow and sackofrice13, I’ve got a regular PS3 Cthulhu, Imp and 360TE and am scratching my head as to why this isn’t powering on at all…
Currently, I’m wired according to Faux’s diagram (thanks for that, btw). Still, neither the PS3 or 360 are registering. Guessing I’m having a problem getting power to the Imp. But there’s a few different suggestions in the thread (I didn’t see one in the original post)
This one, for example, I’m not understanding:
Got the 5v running to the vcc on the cthulhu… check. But what’s this about running the V1 to the red usb 5v, then to the board? I’m not understanding. Right now I’m running V1 to vcc on the Imp. Is that not correct?
Also, like Airthrow’s, the two pads Faux & Toodles mentioned needed to have a jumper - my board came with the points being soldered together. Do I need to do something else?
I’m struggling with this, guys… could really use some help.
I’ll work on the regular Cthulhu part of the guide, you guys. I wish I had known that they required different wiring before I wrote the guide. In the meantime my advice is spend a few dollars more and get the better board, ya cheappies!
