Hey all,
I have a Hobbs overboost switch that i installed today and i want to verify that i installed it correctly.
I read online that you splice it into the black with the red stripe power wire going to the ignitor coil.
engine is a 91 ka24de
so it sits like this without overboost
Power from ecu -> in switch COM -> out of switch on top pin -> ignitor coil
and then when it does have overboost
Power from ecu -> in switch COM -> out of switch in middle (the one that is selected when the switch clicks on according to the side of the switch) -> grounded to chassis.
Will this set up work or is there any ill effects of having the power wire be grounded?
Thanks everybody!
