LNC-2000 install issues. Hey all, i'm trying to install an lnc-2000 in my buddys '98 vette 6-speed. I have the easy part figured out (coil pack connectors). I'm working on the launch control part right now since he doesn't have his nitrous kit yet.
I wired it for activation via the neutral safety switch near the floor and I can get the relay I installed to "click", but now the starter won't engage, as if the neutral safety switch isn't working. Does anyone have a clear representation of how the wiring should be in a C5 vette? I thought I had it figured out but i'm stumped at the moment.

1998 Corvette clutch switch install Did you follow the instructions included with the LNC-2000 for connecting to the neutral/starter switch? Did you use a relay as described on page 12?
Attached is a JPG of that page.
Here is a link to the full instructions as well:

Yes that's the exact diagram I followed, The only difference is that the green wire is yellow on the corvette which i'm sure doesn't make a difference.

One thing that might be wrong is where I sourced the keyed 12v. I spliced into an ignition fuse in the passenger side floor mounted fuse box. Is there a better spot to do it on a C5 corvette?

Clutch/starter switch wiring As long as the source is key-on +12 volt, that should be fine.
If the LNC-2000 is activating then you likely have a +12 volt source. I
If the LNC-2000 is activating when you have the clutch depressed but the starter doesn't then you likely have something on the other side of the relay wired wrong (on the NC/NO side) or you don't have a good ground on pin 86.

Found the issue...
The 12V keyed source I used was accessory only and turned off while cranking. Found an ignition source and boom! Fired right up and worked flawlessly.

12v source Glad you found the problem. I hadn't thought of that as a potential problem - I will try to remember that if this comes up again. Next time I update the instructions I might put a note about that as a reminder.
Thanks for keeping us all informed on the solution - always helpful when we get closure on a thread like this and know how it was resolved.

Yeah that's a good idea! The instructions were pretty good I thought otherwise.
And yes I hate when a thread dies and never gets an answer to a problem. I figured it would be a good idea to update.
Just an FYI for C5 vette owners, I tapped into an ignition fuse in the under hood fuse block. I will have to look at which number it was, I can't remember.
