Hi, first of all i'm new within all of this so bare with me ![Cool 8)](http://www.vemssupport.com/forum/Smileys/default/cool.gif)
VEMS boardversion v3.8 and 6 IGBT + 2 Logic levels
I have been hooking up my VEMS and will soon be able to fire up the engine i believe. But i am unsure that everything i have done is correct, especially when it comes to protection of the ECU, the worst nightmare would be to fry the ECU, so please help me not do that

I'm worried about if i need to place some kind of protection diodes on the p259 channels. I have used "Pin 16 EC 36 P259 ch.1" as a electric fan controller. But i've been talking to a friend of mine, that i might need some diode to protect the ECU.
I've made these drawings

(Bonus question --> i use 875 cc Deka injectors high impedance, will i also need protection diode here?)
Kind regards, Mads.
