V2 with LC-1 wiring

[JUSTASBC]

I have searched high and low, and have been unable to find the proper wiring for the LC-1 (as both NB, and WB) with the V2. Can anyone help me out? I have a 7 wire LC-1, and I have a 4 wire O2 sensor (2 black wires, blue wire, and white wire)
Thanks

What is the year, make and model of the vehicle you are trying to setup? Look here, lots to find with Google. http://www.ls1tech.com/forums/pcm-di...same-time.html

I have an 05 Silverado 5.3l. I have read that post, and when I try and open the "LC1 connections", I get oops, link is broken. That looks like what I need to see, but I just can't see it.

You have to look at a PCM wire schematic for your truck to make sure that the NBO2 heater power/ground is not switched by the PCM... if it is, then you have to power the LC-1 from a source other than the NBO2 heater power/ground.

The LC-1 has Channel 1 (yellow) programmed to emulate the NBO2 signal...
connect yellow to NBO2 signal and green to NBO2 signal return.

BTW: regardless of NBO2 emulation, you should be using serial comms connection to FlashScan V2, see here:

Thanks, that looks like just what I need.
