I have been searching multiple forums and google for which splitter I actually need for my 04 330i zhp with the bi-xenon, to activate the flash to pass lights with the high beams. I?ve also been searching for a free version of the ISTA software to do it through coding. I?m not having any luck with either so far. Can someone help me with the proper splitter? HR sent me a H7 m/f- 9006m, that I don?t see how it would work. What I?ve done so far to upgrade the lighting. Replaced the zkw lights for good AL?s, Phillips d2s bulbs, new lense covers. I did keep the lenses from the Zkw?s, yet to install them. Any help would be greatly appreciated
