did i hook up LC-1 correctly?

[spic21]

im installing my LC-1 and have a few questions. this is how i have it hooked up so far. i did soldier all wires except where i pulled power.

Red-12v switched (to ign.)
Blue/white- grounded to chasis on the same lug
black- calibration switch and led then both grounded
brown- db gauge
yellow- not hooked up yet. needs to go to ecu(confused on which pin)

is this correct so far? i read that people have to yellow to gauge and brown to ecu. i just went off the instruction that came with lc-1 so im not sure if im doing this correctly. im also confused on witch pin to bring ecu wire to(and if i using right wire off LC-1). i would like to keep my stock o2 if possible.

my car is down right now and im doing alot of other work to it (including ecmlink, SD, FMIC and more) so id like to get everything right before i put it all but together.

my best guess on which pin to use would be pin 15 EGR temp. is this correct? if so do i just cut it and soldier the brown or yellow wire (dont know which) to it.

I instaled my lc-1 this same way and is working fine,

about brown and yellow cable, both are analogs outputs, the only difference is that the yellow one is factory calibrated as a narrowband, but you can change this calibration on log works to make both outputs wideband or whatever you want

i conected brown to the gauge and yellow to the ecu

ok well happy i got all that correct. why are there two jacks to plug in serial cable. i should only need one correct? i have then both sitting behind radio now because i was thinking i wouldnt need them since it would be ran to ecmlink. no big deal if i do because i dont even have a radio so access to them is easy. is there a def in the two? if i need one or both all just install them near led.

they are digital output/input, to log or program

Connect the Serial OUT connection with the included 2.5mm stereo to DB-9 cable to a serial port on your laptop.

Connect the terminator plug (2.5mm male plug with no cable) into the Serial IN connection of
the LC-1.
