I like the MSD unit better then the LPE because it seems to be more steady on the twp step RPM, the LPE has more osculation or bouncing. Although we did have one go bad this last weekend.. but we have had LPE units go bad too. Customer lost a race over it, luckily the points series starts this weekend so not a big deal.

I originally ran the lingenfelter unit but I could not get it to work because I had different spark plugs and wires. I'm fighting them right now for a refund but at least the MSD works perfectly.

Its has factory style plugs that go inline to the main connectors for each bank of coils. The unit can be switched by either a 12v wire or a ground wire. I rewired the clutch switch so that it provides a 12 source when depressed using a relay

im trying to wire up my msd 2 step to the top clutch switch, problem is that it provides 12v when the clutch pedal is up and 0v when the clutch is depressed.
is there a way to wire in a relay to either "a" provie a ground when clutch is down or 12v. reversing the output.

I know this is an old post, but I am trying to hook up the MSD 2 step to my 2002 Z06, i want to use the clutch switch but there are 2 wires coming out of it, there is a purple and a yellow, which one are you guys using for the 12 volt power source? I tried both with a test light and neither has power. I want to be able to hook this up to the clutch lever switch so i can use it to launch for drag racing.

You are correct, both wired you tested are grounds that get completed by pressing the pedal/ switch
This diagram you remove the wires from the clutch switch and now send 12 volts to it.
Rather than completing a negative circuit to the computer it completes a positive circuit to a relay
The relay then cloes the connection between both wires
At the same time that yellow (12v+ swiched by pedal wire splits to send a signal to the 2 step
Im assuming the 2step box is switched by +?
Also i would avoid a test light, our cars are sensitive and the current they emit can damage components

Only reservation is that if you use the switched wire from the factory clutch to complete a ground on the 2 step it could fry a computer component. best of luck!!

I dont know where those wires go, without a diagram you are blind.
Say the wires return to the computer and expect 0.5 amps or current then you toss on the 2 step ground switch which feeds in 2 amps of current, overloads that circuit.
Our car's electrical system is sensitive so the best thing you can do is build the diagram from that link which preserved the OEM clutch wiring
I would not connect the wires to free up the switch, yes your car will start because car will think clutch is pressed but that signal also tells cruise control to stop
If that diagram is too complex let me know and ill do my best to make another. I want you out enjoying your 2 step asap
