I wrote up this little diagram to see if the way I want to wire my nitrous will work. Forgive the shittiness of it, just let me know if it will work.

 

FYI: the soldenoids will be getting their power from the Alternator fuse (14), and the MSD switch will be getting its power from the Radio fuse (8).

 

goodnight bump

 

don't know anything about the actual diagram, but there's 5 slots empty slots on the fuse box, all 12v made specifically for accessores, and accepts female spade plugs. definitely beats splicing into a fuse already being used.

you're gonna have to look up which is which tho, hopefully somebody chimes in with that pic

 

if its a NOS or Nx kit, there should be a relay in the mix as well, but yeah i had my old setup like that, with a WOT and toggle switch.

 

yeah im pretty sure you have to use a relay on the output of that msd piece.

 

With a bosch style relay (single pull).

 

/\ thats how it should be set up, without a relay you can be sure those solenoids with destroy that window switch

You have a high current. That's why you use a relay. It can switch a high current with a low current Trigger.

With that pic, I have three power lines. I need one going to the soldenoids (broken by switches), one going to the relay, AND one going to the MSD switch?

Basically, I want nitrous to activate only when both switches are ON and only when the MSD switch is in the pre-set RPM limit. Will that pic accompish that?

You can combine the relay and MSD power. Make sure you have it fused.

Yes, it will only work if you have both switches on and the window switch is within the right RPM.

What? How?

 

how exactly does that MSD window switch work, does it provide an active low (ground), because I have the ZEX window switch and it provides two wires with continuity when the nitrous is supposed to be activated, but It can only handle 0.5 Amps, which is practically nothing for solenoids that can drain over 5 Amps

 

you want it like this:

 

no window switch

 

id wire it like this



with the ground (white wire in this diagram) wire off the relay going to the msd switch
