You want to use the neutral switch as a bypass for the bypass...

Let me tinker with it a little...

The ECM does not send signal. It receives ground when the tranny is in neutral.Ryan wrote:I was wondering how the ecm was sending signal to the neutral switch, and if it could handle an alteration to its circuit. Is it simple? as in, a constant applied voltage?
You're looking at it the wrong way. The ECM input (from the neutral switch) is grounded through the neutral switch, not the other way around. Essentially, you're loading the neutral switch with the relay, not the ECM. And the neutral switch is mechanical, so you should be fine there.Inodoro Pereyra wrote:Anyways, your circuit doesn't work. You're loading the ECU input with the relay coil (don't try it, you could fry the ECU), and at the same time your neutral switch is loosing the ground reference.

Sorry it took me so long. Photobucket has been driving me crazy.
You need to disconnect the neutral switch from the ECU, and use it to drive the relay. The rest is pretty straightforward.
Let me know if there's something you don't understand.

You definitely DO NOT want to connect 12v to the neutral switch AT ALL. I have done this and it WILL start a fire. The other end of the neutral switch is connected to ground, and it WILL kill your neutral switch. I cannot stress this enough. That is how I lost my neutral switch.
Does that not feed the neutral switch 12v?PoisonDrop wrote:
On the relay, hook 85 to the neutral switch ECM wire, 86 to one side of your button, 87 to one side of the starter interlock switch (on the clutch pedal), and 30 to the other side of the starter interlock switch. Connect the other side of your button to a constant 12v source. This should get you exactly what you want.
I will also tell you that if you do what I described, it will NOT click every time you press the clutch.
The relay coil is the load that allows you to do this.Does that not feed the neutral switch 12v?
