Layout is pretty much stock SC, especially in the engine bay.

Given the easy access to three of the four needed LC-2 connections on the left side of the engine bay, I am sorely tempted to put the LC-2 there, behind the plastic cover. Then, the only wire to run forward would be to the gauge. Or are conditions there too harsh for the LC-2?

So under this plan,
- Red to +12V, proposed to rear fuse box. I don't have a rear blower, so that's easy
- Black to ground, proposed just behind the rear fuse box. I'm not clear if I also need to run this ground to the gauge, and / or also to the OXS coax shielding.
- Yellow (0-5 V) to gauge
- Brown (0-1 V)to lambda box. Does this particular connector have a name or known source? It's a one-wire connection as far as I can see, and I'd rather not cut the connector off of a perfectly good oxygen sensor.

Andrew,

I dread this as I don't own a Windows computer with a serial port, and I think that's what is required to change settings. The oxygen sensor input is ignored until the motor warms up- how does the oxs warm-up time compare to engine warm up time? Or is this a warm start problem?
