Ok here's the deal, I recently found out my Mallory 685 has a two step. DUH!! Well I am going to wire up the two step and also wire up a line lock. But my question is this:

When I wire up the two step, my understanding is that even though my pedal is all the way to the floor, it will only rev to my desired RPM. But, I have my nitrous wired up on a window switch and a WOT switch. So, if I have my pedal to the floor wouldn't it be spraying while I am sitting at the line???

How do I go around this problem or how should I set the two step/window switch???

 

anyone?

 

Turn the arming switch off for the N20 and then use a push style button Like a purge button for the two step, and mount it close to the arming switch. So then you turn off the arming switch, hold the two step button down, then press the gas pedal to the floor, launch, let go of the button and turn on the arming switch let the window switch do the rest. I will be hooking my two-step up soon and this is how i plain to do it. The Mallory is a nice box i love mine.

 

See that is how I was thinking to hook it up, but the deal is I really don't want to have to worry about arming my nitrous switch while I am trying to launch. I have a Hurst T handle with 12v button on the way and I am going to wire up a DPDT toggle so the middle is off, one way is my line lock and the other way is my two step.

What if I would have my window switch arm a few hundred RPM higher than the two step?? I wouldn't have to worry about them crossing over and one being off since they are both being ran from the same ignition. Think this would work?

 

That seems like it would work to me. But there has to be a better way to wire it up all togather. What if you wired in a normally closed relay into the nitrous system that was activated by the two step? That should let the nitrous system operate like normal until you hit the button for the two step and it shuts it down. I'm not positive this will work because I've never tried it myself, but it seems like it should. Anyone else have some input on my theory?
It would be really nice to just stage, hold the line lock/ two step button, put the pedal to the floor, and let go of the buttom on green. Then all at once it disengauges 2step/line lock and activates the nitrous.

 

If someone could write me up something to wire this up that would be great. I never thought about the line lock at the line. I was just going to use it in the burn out box but now I realize you have a good point and I should use it for the line too!!!!

 

I just got a line lock and am going to wire up my two step on the Mallory. I ordered a Hurst T handle with a 12v button and was going to use that to wire up something.

My original plan was to wire up a DPDT switch where one direction would be for my line lock and the other would be for my two step. I could have the switch in one position when I was doing my burnout and then put the switch in the other position when at the line using my two step. Well I was hoping that I could wire it up somehow where I can have the line lock on one position of the DPDT switch and then also have the line lock and the two step on the other position so when doing the burnout I can just use the line lock and then when at the line I can use the line lock and the two step.

Well also I am running a window switch from the Mallory 685 and a WOT throttle switch to arm and use the nitrous. Well if I am at the line and I have the pedal to the floor I don't want to be spraying the nitrous. Any suggestions?

 

Is this for your '97 6-speed car?

 

it sure is

 

Have you considered operating your 2-step off the clutch switch and the line-lock off your T-handle switch? I'm not familar enough with the Mallory 685 to know for sure, but it would seem that if the 2-step is activated, it would lock out the nitrous activation. If not, then a relay activated by clutch engagement or SPDT clutch switch would take care of that as well.

 

I've got really no idea what you guys are talking about, or how they all work, but I've got a suggestion. Why not have momentary pushbutton on the T-handle that's normally open? Hook that up to the ground on your line lock. Pull up to the line and just hold the button down. When you launch, slide you thumb a bit to release the button and it'll release the line lock. Or, you could set-up the line lock to work on a flip switch, like normal, and then splice into the ground with the afore mentioned method. That way, when you pull into the burnout box, you could flip the switch to engage the line lock so you don't have to worry about it, then disengage it and use the momentary push button to engage it at the line?

 

^ That would work just fine, but he wants to use his two step also and make sure the nitrous isn't on when the two step is engauged. The best way I think to do it would be wire it all to the T-handle button with a seperate toggle for the line lock during the burnout.
The clutch switch is a good idea, never thought about that one.

 

I've got it all figured out thanks to s_willis. The diagram he sent me a few months ago already had provisions to wire up a two step, line lock and nitrous kit. I was just too stupid to look at it closer!!!

 

Cool, post it up for future set ups.

 

I'm curious to see the wiring diagram you used to see how it compares to what I came up with. Could you post it or send it to me?
