Lc-1 wide band grounding?

[talonsteve25]

I just bought a new lc-1 and iv searched a bit on how to hook it up and such but i didnt really find an answer of where to ground it? My idea was ither where the ecu is grounded, of the battery or off the motor through the fire wall. What are your guys set ups? Ideas?

The blue and white wires should be grounded on the same lug to a chassis ground, not a sensor ground (ECU).

So just anywhere? Or should it be relatively close to the ecu? Or does it even matter? And one of your links said the blue and white wire should be grounded separately, so if i was to do that i would just use two lugs one for the blue wire and the other for all the other grounds. But i would put them close together, is that the right way?

I'm not sure which link you read that in, but the blue and white wires should be put together in one crimp ring.

I believe mine are mounted to one of the brackets near the ECU. Either that or my distribution block (however I don't see it in the picture).

Any piece of metal on the chassis is a good place to ground. It doesn't matter where on the car. If its close to your radio, I would just put a spade terminal on your ground wire and put it under one of the screws that holds your radio in.

Any piece of bare metal. Painted, powdercoated, anodized, rusted, etc. will not allow for a good ground.

"The BLUE and WHITE wires should all be grounded to the same ground source and although these grounds are of the same source, the BLUE wire should be wired separate from the WHITE wire to avoid analog ground noise. Optimally, these (and any other MTS device ground) will be soldered to the same lug, and connected to a single point. When this isn't possible, connect each one to a separate lug, and attach in close proximity. Multiple lugs on the same bolt is not optimal, and can result in unwanted signal "noise." When possible, soldering is always better than crimping. "


Actually snowboarder this is your quote from the first link, you qutoed from some one else and it says blue is apart from white?

Brian just got lazy and didnt want to post a link...He's usually really good about this stuff. What happaned today Brian? I'm just screwing with ya btw...

But really yeah any chassis bare metal will be good enough...

Alright Ill wire it in tomorrow, thanks for the help guys. Oh and one more thing am i suppost so hook up the push button and the led even with the db guage?

That was a quote from Innovate's manual for the LC-1. I kind of understand it, but I think it is a bit confusing and contradicts itself. I followed the part where it mentions being soldered to the same lug. My guess is by "separated" they mean both wires need to run to the grounding point, not one wire with the other spliced into it before hand.

I'm not familiar with the DB gauge so hopefully someone else can lend a hand.
