All this is too complicated for me. Does anybody know who can do this service... I don't mind paying a few $$. I've got about 3x 540ez's and need a 3.5mm socket to them.

OP can you repost the photos of this mod on the 550 EX? I clicked your link to the FM forums but the image is missing.

I'd like to see what you mean when you say there isn't as much room in the bottom of the 550.

Thanks

I have 6 Canon 550EX's and I used the mod instructions found here.....
And I have had ZERO problems. LOVE all of my modded 550EX's now!!!

Google 550EX mod shows this link...

Just following.

"raising from the dead"...

using a 3-pin or 4-pin plug, its possible to pass power from flash to receiver (and also half-shutter signal to wake up flash), so the receiver is powered from flash batteries. also, its possible to make the receiver turn on together with the flash, so its s no-waste, perfect "symbiotic" working method ;P

i did to a 580ex2 + rf-602:
