Help me with LC1 Wideband install plzzz
 

I'm reading all kinds of conflicting information and I'm a wiring noob and totally confused. All I am trying to do is wire it up to get the readings.

One problem, I'm missing the "switch" for calibration. Any chance my problems are because I have yet to calibrate? Can I rig a switch?

Problem: The numbers just bounces all over the place from 22 then goes to 7.x then blinks, then goes everywhere, then back to 7 and blinks. Sometimes it seems like it just stays at 15.x. When I first power it up, it does climb slowly up to 14, then soon after it goes wild again.

This is how I have it wired up

Black/purple from gauge, blue/white from sensor, all connected to one ground.
Blue signal wire from gauge connected to brow signal wire from sensor
Red power from gauge and sensor, connected together to one wire, then wired to cigarette power.

Scouts honor, I'll put together a picture how too if I can just figure this out.

Did you buy the unit used? Sensors usually bounce all over the place when they are bad.

Yes I did.

here is a video

All I needed was calibration!
I'll make a picture guide when I plug in the MSP where I'll also clean up the wires/connections. :D

BTW, I connected both power and ground wires to the cigarette plug.. Is that okay?

To get a cleaner signal it is recommended to power it with a relay from the fusebox or battery. And ground it to a signal ground. I used the ECU ground. If you have any issues with it turning on on startup powering it with a relay will fix that. It errors out if it doesn't have a full 12v during the warmup sequence.

I actually did have that problem one time I think. It needed a recalibration after sitting over night. It hasn't happened again though :/ next week is spring break so I want to clean up the wiring situation. If I do the fuse box/relay thing can I run all my gauges off that one line? Or will it be different once I have the ms3 hooked up?

Okay so the thing lost calibration again and so I hope it's only because of my wiring. I'm going to buy whatever I need to wire all my gauges. What would be THE BEST way? I don't mind wiring from the batter or the fuse box. Also, any recommendations on what types of connections to make? Is soldering really the best method?

I use solder heat shrink crimp connectors and they work great.
