Hi all,
I've been searching for the past couple of hours for the wiring diagram (originally posted by soundengineer) to wire an LC1 to work as a narrowband and as a wideband for HPT. I had done this once before (a few years ago) and I need to re-do all the wiring, but I don't have access to the wiring diagram anymore. The one originally posted (located in the sticky) no longer works (the link is dead: http://www.audiohelix.com/tuning-documents/lc1/lc1.htm). Does anyone have a copy of that diagram, or know where I could find it? I've searched ls1tech.com and hptuners.com but no luck so far.
Also, I did find this other diagram in my searching. From my memory, it looks a little different than the original, but I could be wrong. Would this work?

Thanks!

Your diagram look right from memory but as poconojoe says, page 17 is the "beginning". You can certainly verify which wires are correct with a multimeter by measuring voltages but don't trust the manual. I found it inaccurate with my LM-1 (same for the LC-1) because of wire color coding. I posted my success on the innovate forum several months ago and it should still be close to the top because of the small level of LC/M-1 activity within the forum. I would need to get on the forum to give you the link but I think I have the same info here on LS1TECH somewhere.
From my perspective, Innovate has abandoned forum support for the -1 series in favor of the -2. The only problem from my post will be that the wire colors will be different for your LC-1 but I think I have explained it well enough for LC-1 owners to determine the correct wire-up.
