I purchased what I believe to be a DP-DT switch from Painless Products through a local speed shop. It has "off" in center position and "on" both to the L and R of off. ON-OFF-ON. I am OK with that since I can easily determine it is OFF without seeing switch under dash..

EBL rear view of switch shows as follows:
1 4
2 5
3 6

So am I correct in that:

EBL-ECU A4 wire goes to pos #2 and ECU C8 wire goes to pos #5(formerly served EGR).

Switched 12V goes to pos 3 and pos 6 is ground.

The fact that is has two "on" positions concerns me.

Thank you.

 

Yes, that is how it is wired. The center off is an oddity in this case. But will work.

N2O off will be center position or the position of off.

Can always put an LED in place of the solenoids so that the driver/tuner can test out the wiring ahead of time.

I read another tip on verifying functionality is to power up system with bottle off and verify on WB the excessive enrichment along with obvious exhaust note change.

 

That's what I did. Then armed it, made it activate @ 2500 RPM and took it for a ride, works like a charm for me. Till the N20 noid took a crap!, lol. Now I haven't driven the car in like 6 months due to other problems.

buck at the lab, how are you making out with your set-up. feel free to call me, pmed you my number.

 

Liquid: For others info. NOS says activate over 3000 rpms. Chev High Perf says 3500 rpms and off 500 rpms under shift point...

 

I had mine between 2500 and 3000, right off the converter. My shift point was about 5600 so it ran right out to that. I never got more track time to play with it much more.
