I'm going to install a second pump intank and wanted to know if the diagram I attached looks right. I want the second pump to come on when I activate my master nitrous arm switch. I think I am thinking too hard and making this more difficult than it needs to be but I just want to be sure I get it right.

Add a fuse to the heavy power wire leading to the relay as close to the battery as possible.

For your arm switch are would you be able to use a hobbs switch? I'm not how the hobbs switch works, I just know that is what people use with two pumps. Kinda hoping someone could explain how it works. I know Steve has them for sale though.

i would wire it to the n2o silinoid power wire. run # 86 wire to the power wire on the n2o. when you mash the gas and the n2o is activaded it will turn the relay on and send power to the pump

A Hobbs switch activates on pressure. So a pressure system, turbo or supercharger, will activate it. If you are not one of those, another, such as a self-activated switch, should do.
And absolutely put a fuse right at the alternator/battery. IIRC, 20 amp.

I have a front mount, so I'm going to use that when I install another walbro. I just have to find out exactly how that works and how to install it.

Are you guys pushing the extra fuel through the same stock fuel line, running dual lines, or have you switched to a return style system?
