LNC-2000 on a LSA or LS9 Actually the LNC-2000 DOES work on an LSA or LS9 BUT the LSA and LS9 use different coil pack connectors compared to all the other Gen III/IV GM V8 engines so the LNC-2000 is not plug and play compatible with the LSA and LS9 engines like it is with the other Gen III and IV engines. The LSA and LS9 combine the injectors and other sensors in with the coil signals so the connectors are different on the harness.
At the time you purchased the LNC-2000 we did not offer a version that was specifically wired for the LSA and LS9 engines so to use an LNC-2000 on a LSA or LS9 you had to either:
We now offer a version of the LNC-2000, the LNC-2001, that has the LSA/LS9 specific connectors and wiring.
BTW - not sure how this has anything to do with the original topic of this thread.

- rewire the LNC-2000 harness to the mating connectors for a LSA/LS9 engine (as indicated in our LNC-2000 instructions)
- change your LSA/LS9 harness to have separate coil and injector harness connectors like other Gen III/IV engines

CTSV tach signal Are you referring to the pinout document Ryan posted?
If so, that is the correct location for the tachometer signal on a 2009-2014 Cadillac CTSV. The production harness is not populated in that location so you have to add the pin and the wire to the harness connector but that is the correct location.
It is the same location as the ZR1 Corvette (2009-2013) that uses the same ECM (and in some years the same ECM software operating system) as the CTSV but the Corvette still has a direct output from the ECM to the dash for the tachometer signal so you don't have to populate that location on the ZR1 (since it is already populated).
That pin (pin 25 on the blue connector C1) is also the same location used for the tachometer signal on all of the other E67 applications that I am aware of including the 2005-2006 CTSV and the 2007-2009 Trailblazer SS. Again, on those applications that location is populated because the instrument cluster still gets a discrete RPM signal from the ECM via a dedicated signal output wire.
If you don't want to have to populate the tachometer signal pin on the ECM harness then you can also get the tachometer signal from the coil connector.
