Hey, nice mod on the 430, zoti.
I wasted way too much time on off camera speedlight setups, going from ETTL, wired, optical slave, and the lastest--Ebay trigger. Here are ways that is provened to work, for me anyway.
A. 430 and 383 connected to a spliter, then sync cable to camera.
B. 383 on sync cable, 430 triggered by Wein Peanut optical salve; two flashes could switch places.
C. Both 430 and 383 trigger by the same Ebay radio receiver.
D. (not picture) Ebay trigger trips the master 580 in manual mode, 580 trips the slave 430 by Canon wireless mothed, 430 triggers the 383 with Wein Peanut.
