Default Efi Live Cos 5 wiring?

I searched and couldnt find what I need.

Can any one help me with Bulding the switch that will Arm the nitrous, and go to the pcm for Efi Live COS 5? Im getting it setup for when I get tuned they can work their magic,

Someone out there has to be able to have a diagram or some instructions


Thanks

You can go to EFILive and do a search. But I believe it is pin 56 on the red connector and it gets a ground signal toggle the mode. You may want to verify before you do it though.

The EFI Live forum has the info.

Red pin 56 is what you need to to run a wire to a toggle. From the toggle you go to ground.

Then you load the COS 5 over a 2002 Operating system. Follow the COS tutorial.

Pins for the PCM are cheap you can get them from

I used the 18 Guage one.

Valet mode (Used for Nitrous Monitor)...Punch the connector through the yellow membrane, you should feel it "Snap" into place.



Run the wire to a toggle/rocker

Run the toggle to ground

When the switch is grounded and w/ COS 5 correctly loaded to your tune, it will use the nitrous monitor tables.

You can bypass the switch and go with hooking it up to the noid and when the noid grounds it sprays and grounds the PCM pin automatically using the nitrous tables when spraying.
