Flandrs Posted December 19, 2017 Report Share Posted December 19, 2017 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 Quote Link to comment Share on other sites More sharing options...
Shedley Posted December 19, 2017 Report Share Posted December 19, 2017 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 Quote Link to comment Share on other sites More sharing options...
Flandrs Posted December 19, 2017 Author Report Share Posted December 19, 2017 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?

Shedley Posted December 19, 2017 Report Share Posted December 19, 2017 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.

Adamw Posted December 20, 2017 Report Share Posted December 20, 2017 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?
