OK, I have one on my 6 digital but haven't used it yet and don't really know how. I'm putting on a line-lock so I can warm up the slicks (which go on as soon as I can get down to the tire shop). Do I wire the two-step in to the line-lock with a switch so it gets a 12v signal when I stage? I was thinking the line-lock could hold athe front tires against the converter at 3,000 rpm while I buried the pedal against the two-step. Then releasing the button would disengage the two-step limiter, release the front brakes and put the car in motion. I just dreamed this up this morning but it seems to make sense. Am I close???

Scott,That will work if was a manual tranny. But, the front wheel line lock won't hold the car back with an automatic. (unless it was a 5,000 stall and you two stepped it to 2,000 or so)
Connect the two step (blue wire) to 12v from your brakelights. You'll need an arming switch, so the two step isn't activated during the shutdown. SteveW [This message has been edited by steve'66 (edited 09-10-2003).]

So I'm guessing it ought to be a momentary switch just to make sure I don't forget???I'm also guessing the 2-step could be wired to the transbrake if and when I get that put in for a better launch (better reaction time)? Thanks, Scott

Hey Scott, do you have front discs on your 69? When you get your linelock hooked up could you post on how you hooked up the linelock to your brakelines (what adapters you used and where you got them)? I could never find the right adapters for my 69. Thanks.

Most folks that wire up a 2 step to thier line lock put a line lock on both front and rear tires. Otherwise, (normally) one set of brakes wont hold it at the starting line. They generally call that a "poor man's transbrake."

Afret, I picked up the Hurst package with the line kit. Haven't hooked it up yet, but whatever lines I don't have I'll flare myself. I don't anticipate too many problems (that's what usually leads to the real problems).  Kid, I was planning on the line-lock for the front only to heat the tires. Hadn't thought about a second one for the rear brakes. Properly set up that could give me better reaction times for a lot less than a transbrake. Seems like it would load the chassis better too. If I wired it to the rear line-lock, that would give me the 2-step trigger I need. Thanks for the help, Scott

Kid, putting a line lock on the front and back breaks is not legal nor is it safe. Most front brakes (disk) can hold a car with no problem to round 1800 to 2200 rpm.Scott, if you are going to run a line lock put it on your shifter handle. Hurst and B&M both make a handle with a switch built in. I like to start out in first and then into second when I feel the engine starting to bog. If you are running an auto never come out of the water onto dry pavement. That is an easy way to frag your tranny. As far as the two step, put that switch on your brake pedel. It will deactivate when you take your foot off the brake. I do not know if you are carbed or are runing EFI, but most carbs with need adjusting to run a two step. Also you have to make sure that you do not load up the engine too much with unburnt fuel or you will have a real big bog off of the line.

Depends on the division in which you live. IHRA and NHRA divisions 5 and 3, it is perfectly legal to run a dual wheel line lock wih a 2 step in the no box class. Where I moved from, lots of people do it. Nothing unsafe about it if it is set up properly. As for 2 stepping below 3 grand, MSD has a warning label right on the package that using the 2 step that low can cause crank breakage.
As for the burnout process, if you have enough motor there is no reason to start in first gear. I start in second and go to high, as does KK with her glorified street car (and she doesnt even have a linelock.) If your car cant start in second gear and turn wet bald tires over sitting in water, you have something wrong.
