Nitrous and transbrake wiring system
Nitrous and transbrake wiring system I am using a standard bosch 5 pole relay to control my transbrake on my glide. I am running a very normal plate kit on my car with no bells or whistles just a step retard in my ignition box.
I am using 84 and 85 as control coil of the relay obveously, 86 as my load supply wire, and 87 as my transbrake supply wire.
My question is may I use 87a (the normaly closed pole of the relay) to engage my nitrous system so that as soon as the relay releases the transbrake the nitrous kit is activated?
In essence the relay will serve as a cirquit interupter for the nitrous as long as the transbrake is engaged but as soon as the relay returns to its relaxed position the nitrous is activated.
Anyone doing is?

Yes that is exactly what I am getting at. Mine is through a WOT also. How much power does your car make, what trans, how much spray, tire size, and what kind of 60' times does it cut if you don't mind me asking????
Thanks for the input.

Consider what I do, for added safety & reliability.
I also have the 5 pole relay to cut the N2O when the trans brake is engaged,
and when you release the button the N2O is on immediately.
What I do is run 2 relays and 2 WOT switches because I've had both go bad.
Those little micro switches are not really made for the abuse of a race car.
Good luck.

That's basically the same thing we use the micro switch for.
Us old carb guys don't have a tps.
As long as you use 2 relays, you know you will get a full pass 99.99% of the time.
Like I said, I've had 4-5 bad relays over the years that would not engage.
I don't really worry about the trans brake relay because it doesn't have 25+ amps going through it and they seem to last longer??
I can't even count how many micro switches I've broke??
It has been a lot better since I stopped using that little cheap bracket.
Now I use a nice solid piece of alum and the switches don't get beat up as much I guess??
I don't know where the photo went?? but I can send it if guys want to see how I did my dual switches.
