Wiring

Recommended Posts

Hi

I'm wiring in a g4+ storm ecu onto a Mitsu outlander 2006

But i'm stuck on getting the engine relay to work properly

Relay activates with ground on pin 57 at oem ecu

with link we cannot activate like that without a relay so i mounted a relay  between link and the oem harness of the car like this

 

30 Aux signal ground from link

87 ground signal out to engine relay

85 Chassis ground

86 Ign +12v

 

works great but when ignition is turned of the relay still draws power so it won't power off, if i manually set +12v to 86 it works but if i use power from the ignition block it doesn't work. It goes backwards.. Any help to sort this out would be much apreciated

Just use the standard relay, and let the link ecu switch it as an gp output, who’s always on, when the ecu is on

just make shure the pin 30 of the engine relay is a ignition switched power because aux outputs go to ground when ecu isn’t powered up

exactly, but it didn't work so i hooked it up like this instead

30 aux ground from link

87 ground signal out to engine relay

85 Chassis ground

86 aux6  +12v from link

didn't work either, probably because when the relay has drawn it's power the ground never release so it cannot turn off
is there any other way to wire the relay so it will work to send out a ground signal?

If your engine relay is Ignition switched, then it wil switch open anyway, if you turn of the ignition, so i think there is something not wired up as it should.

What you also can do:
Take an ignition switched power to terminal 85 of your engine relay, and connect terminal 86 permanently to chassis ground.

Im having trouble understanding what you are trying to do but your relay wiring sounds completely wrong...

Why do you even need a relay?  The ECU aux will send a ground out whenever it is active.  Cant you use this directly to switch your main relay?
