Bmw e46 ms42 boot pin location need
First time booting this ecu so I cant get this ecu to boot mode

Tell me if I do something wrong here instruction what I use for 512kb read http://www.autonumen.com/blog/2015/11/20...-ms43ms42/

What I did :

Connected all pins on ecu like on instruction

I connected pin 7 and 26 on ecu ( power pins) then I connected on black socket + of galleto 1260 , then connect all them to 12v + battery

Gnd pin 4 connected on ecu like on picture , I connected boot pin with gnd wire and on boot pin 104 , than connect all them to black socket minus ( - ) of galleto 1260 and on battery minus

K line pin 32 connected on ecu like on picture , and on white socket K on galleto 1260

When I power this I have power on galleto light go on , after 6 sec I remove boot wire from pin like in instruction try to.connect and I got error ecu not in boot mode

I use JM garage flasher like in instruction

I do somethings wrong?
