And what about feeding the 12v into the gnd input on the ecm?

Because 12v - n switch - gnd = fire.And to address the previous two posts... whats the difference if it goes from 12v - n switch - gnd or 12v - n switch - relay -gnd. Same shiz. too much current either way.
So you're loading a switch?PoisonDrop wrote: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.
Ryan: if you do this you will be feeding +12V through the relay coil to the ECU input. DO NOT DO THAT.PoisonDrop wrote:You guys are reading way too much into this. Here's what you should do:
First off, put your tranny in neutral and test the ECM wire coming from the neutral switch for continuity to ground. Just to make sure. If you are concerned about the ECM, you can pull that pin while you're testing, but you should be fine.
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.
Sorry I can't draw a picture, but I'm not really set up to scan and upload stuff from this computer. If you'd like, I could e-mail you a diagram...
I will also tell you that if you do what I described, it will NOT click every time you press the clutch.

Who did ever say the ECU would provide the +12V?PoisonDrop wrote:What I'm trying to tell you is that the ECM does NOT provide 12v to the neutral switch. If you do what your diagram says, and hook up 12v to it you WILL kill your neutral switch. I have done this before and I still do not have a neutral switch.

If you involve 12v without a load it will be like touching 12v directly to ground. With the added load of the relay it acts like a regular circuit. The neutral switch is just shares a ground point for that circuit.Ryan wrote:howso...? If you involve 12v with the neutral switch anywhere, as I understand it, it will toast the ECM.
