LC-1 widband hook up

[W_D_R]

1. brown and white with blue. connected to A1
2. it is grounded to main bar under dash.

LC-1 black wire is not a ground wire...
if you short this to ground you go into free air cal mode ...
if you don't release this from ground the LC-1 stays in free air cal mode...
if you have the black wire connected to ground then this may be the problem.

Brown is analog out #2 positive do not connect to ground.

6 wire LC-1
Black > Calibration wire (to momentary push-button switch between ground )
RED > switched 12v positive
BLUE > ground
YELLOW > Analog out 1 (to V1/V2 AD+)
BROWN > Analog out 2 (to V1/V2 AD+)
WHITE > System Ground (to chassis ground)
7 wire LC-1
GREEN > Analog Ground (to V1/V2 AD-)
connect both GREEN and WHITE wires to the same V1/V2 AD-

My lc-1 has 6 wires. none of which are green.

Yellow- goes to nothing
brown- v2 ad+
white- ground
black- to momentery push button then to ground- to led.
red- 12v switched power- to led
blue- ground

White w/ blue dots- v2 (ad-) to ground. I added this as a ground.

I don't remember, but it seems to me that the led should go between the black wire and ground (white) (in parallel with the pushbutton switch).

as you have it wired, does your led light up...?

if it does, then it's holding the black wire at ~0.7-1.2V below battery voltage (I think the LC-1 doesn't like this).

[W_D_R]

Your correct, its not to the red. Here is a diagram of how I'm wired up. I have all my grounds spliced together then ran to a single point. Should I change this or could efi live not br programmed correctly. I'm confused on how LM would read what I believe to be correct and efi read different.




Thank you Joecar and Mr. Prick for all your help!

The white wire should go to chassis ground.
Does this White w/ blue dots-
go between the LC-1 and V1/V2
or is it V1/V2- to chassis?


IMO
tape off the black wire and if you have V2 use serial connection to the LC-1.

I ran the white with blue dots is an extension of the white wire.

[mr.prick]

Here is how my LC-1 is wired:
power and ground (red + blue) come from the PCM
analog#1+ (yellow) to V2 AD1+
analog#1- (green) to V2 AD1-
system ground (white) to chassis ground.

.

correct.
