I created a Video demonstrating how to use an MSD 6AL2 with two Rev limiters to control your burn out and launch ... This basically giving you two ways to use the first rev limiter and use the second one as the catch all when racing.
I think you could also wire up a separate hot wire to a separate button for the line lock to use only the line lock without the two step turning on when doing a burnout then after do the staging process like in the video using his method engaging two step and line lock together. Good video btw about to do this myself. Helped alot. Def gonna wire up a light too now.
Would it be possible for you post a pic of the micro switch mounting on the clutch? I have a 78 trans am and would like to install this set up. I already installed the MSD box and just need to wire up my switch and line lock. Also a close up pic of the relay would be good too. Great information and video! Thanks!!!
Is the clutch switch positive or negative? In your drawings, its showing the clutch as 12v (+). Most forums show the clutch switch as the negative connection. Also there's two sets of harnesses on the clutch switch. Which one did you use to tap in?
Wait a second - you have to use the clutch to do your burn out. I didn't see you touch the clutch when doing your "second gear burn out". Seems like you would need a toggle to select burn out (no clutch activation) and to arm the clutch activated switch for the launch. Tell me if I'm missing something... thanks for posting this!
Brian David to do the burn out you just use the button, shifter in 2nd gear and clutch down. When you release the clutch you are still holding the button which energizes the rev limiter. Even if the clutch is released. You could even shift as long as you hold the button.
I'm really just wondering how you wired everything up ? How does it work like that with the clutch switch ? And how did you do that set up on the shifter
