I'm just in the process of re-wiring parts of my EMS (Wolf 3d), mainly just the relays.

So, the way I had my injector power relay wired was like this:

Pin #30 +12V from battery
#87 +12V to injectors
#86 +12v from IGNITION
#85 to ground

But as I'm reading the manual, I says the following:

"The Wolf3d injector outputs ground the injector relay."

Does this mean that the relay itself should not be grounded via the #85 pin? Since its grounded by the EMS grounds.

If that is the case, should I wire:

#30 +12v from battery
#87 +12v to injectors
#86 +12v from IGNITION
#85 +12v to injectors

Or did I have it right the first time?

I really stink at electrical stuff, so I would be gratefull for any help!!!

 

someone must be smart on here...
