Default Wiring gurus, step inside!

Next week I am going to start with my head swap. At this time I will be also upgrading my fuel system. I bought a Kenne Bell Boost a pump and the racetronix harness and I only want the boost a pump to come on when I activate my nitrous system through the switch on my switch panel. How would I go about wiring this?

I would think the easiest way would be to replace NOS switch with a "double pole single throw" switch. Wire the NOS to one side and the KB BAP wiring for the vacuum/pressure switch to the other side.

Very easy, simple and foolproof.......

It is just a switch with four lugs and two positions ( ie one position of the switch is off = contacts open and the other switch position is on = contacts closed. There is no electrical connection between the two switches.

The switch for your NOS is most likely a single pole-single throw..

The double pole acts just like 2 separate switches built into one switch.

Just wire your NOS to one side of the switch and wire the BAP vac/pressure switch wire to the other side. The wires will proably be red and black and they can be hooked up either way, it makes no difference as the switch is just connecting the two.

Your new "DPST" switch will replace the vac/press. switch...

So my Nitrous activation to one side of the switch and the BAP to the other? And....The racetronix harness from the alt. to the fuel pump and BAP and the BAP pressure switch to the Arm switch of the nitrous system? If that it, it doesnt seem to hard
