I'm just finishing up the installation of a new trans in my 90 LX. I'll be running a trans brake for my first time and I'm trying to decide on what type of trans brake button I want to run. Does anybody prefer 1 over another? Are there any advantages or disadvantages of a remote button on a coil wire?

Thanks

I loved my Griner. Some trans brakes need to be held on for you to be able to use reverse. Not a Griner, and why I liked it.

You should be able to get around that by wiring in the reverse tail light if you have to tbrake in to use reverse. Thats what I'll do with mine but just haven't yet. As for a button I've used cheapy ones before and now I have a decent Jegs branded one. They can get pretty expensive so it depends on how competitive and dialed in you want to be.

This is the jegs one I have used.

I don't get it. Wiring a reverse light engages a gear? I should add I had a Griner valve body too. Rmvb

It all depends on how it engages. Mine for instance engages with a 12v source. For reverse to activate I have to engage the tbrake so sending 12v to it will allow it to shift into reverse providing i'm in R or N. Alternately I could splice in my reverse tail lights 12v into that wire so it would send 12v to the tbrake if the shifter is in R.

I got ya. Thought you were talking about just the rev light itself.

Good info so far. I'm probably going to order something like the Jegs button posted above. I'm leaning towards mounting the button on my center console near the base of the shifter. I don't want a remote button hanging loose and bouncing around while making a pass or cruising on the street.

I haven't looked at a wiring diagram yet, so I'm not sure if I'll have to hold the button to engage reverse.

TCI small button micro switch is my preference.

I have one on a coiled cord for the nitrous and one on the console for the TB.


387600 and 388400 are the part #s.

I'll be running nitrous also. I'm still researching and trying to figure out how I want to wire everything together. I'm planning on adding a 2 step and I'd like to set it up so that I'm spraying as soon as I let go of the tbrake button. I have an RPM window switch and TPS activated WOT switch in place already.

Depending on your launch RPM and window switch settings, be sure to wire it up with dual relays so the TB button interupts the N20 switch signal.

There are a couple companies that also offer "pre-built" units that do the same thing

Thanks for the tip. I knew I would have to use at least 1 relay. I didn't realize I would need 2. My car is a pretty mild street/strip build. I have a 3500 RPM converter, so I won't be launching it at crazy RPM. My plan is to set the bottom of the RPM window to just below my launch RPM and interrupt the nitrous until I release the button.

One relay for the TB, and one for the N2o.

They have to be wired to each other though so it interrupts properly.

Ahh okay, thanks for clarifying. I have 1 relay already installed to switch the nitrous and fuel solenoids on and off. I just found a wiring diagram on NX's website that is helpful. Thanks for helping out a newb :bigthumb:

You will probably want to use a diode so you're not turning the rev lights on when you get on the brake

Matt come by my office and we can figure out all your wiring and build a harness

In! If I can find some time next week, I'll stop by.

I really don't care if the reverse lights turn on. As long as the track officials don't give me any crap for it, I'm not worried about it.

I just ordered a Dedenbear XL button. I'm going to mount it somewhere near the base of the shifter. I may make a panel to hide it in the ash tray and fix the broken ash tray door so I can hide it when I'm just cruising on the street.

I also ordered a NX 60 amp double throw relay to interupt the nitrous system from activating while on the brake.

It was the relay NX suggested. I'm sure a 30 amp would have done just fine. The relay has a nice pigtail on it to make wiring easier and it wasn't very expensive. When I'm ready to blow up my engine so I could build another, I'll spray 30 stages. lol
