...I have the 4 pin connectors with wires in the pins that are long enough that I can solder probably right on the GPS board...

Be careful not to make them too short because the reason for the aux mag is to get it as far from the magnetic disturbances caused by the motors and power wiring as possible.  Within reason the higher the better on one of those GPS mount masts.

You are right. I will add some wire, the ones on the plug are only 5" long

Thanks again

After boot of fc i connect it to lp but i2c is always orange...

Dead you read this form fully?
Because if you did you know what you could have done to have it working

Anyway i have the same gps. If you cant get it green you need delay firmware.
How why where -> read, its all on the forum

Okkay but the value i need to use for grren i2c is??
Do you have a same antenna and you have solved with this firmware?

Have 2 GPS supposedly with Mag!  Pics below. 1 is M8N other M7N. 
I have looked at posts pics of M8N and it says no mag chip.  However if I look with a magnifying glass on mine there is a very flat chip or something there.  Question is this the mag chip?  Also I do not see the SCL and SCA labels on any pads. Assuming I do have the mag chip where do I solder the 2 wires for the Flexi port?

It appears to me that the M7N has the mag chip? Am I correct?  I plan to solder the 2 wires on the pads labeled SCL & SCA (or do I have it wrong looks like SDA) to connect to the Flexi port.

Thanks

Roy

The pictures didn't make it for some reason.

The mag chips are tiny square chips labeled either 883 or 983.   There's a pic of a gps with one in the post https://forum.librepilot.org/index.php?topic=1555.msg11573#msg11573  and my answer to him (about a minute or two ago) tells about how they're wired up.  If that doesn't match your gps well enough go ahead and post your pics here and I (or someone else) will help you more.

Sorry forgot the pics.

[Jhinta]

You can clearly see above pic is missing a chip that sould be te mag and the other on has it on the white board

Just to be sure, I mentioned in my post that there is some sort of very flat chip or maybe some sort of thin plastic piece soldered in the space for the chip. It has the 90degree arrows on it and a white line on one edge. If I look with magnifier its is not just the circuit board, there is something soldered or glued on there?

No, he's right, the upper one (black board) doesn't have the mag chip on it.  The arrows/line are printed on the board.

The other one (green board) has one and you should be able to add wires and use it.  The SCL/SDA pins where the wires solder on are clearly marked.  Details of how are in the post I referenced a couple of posts up.

Man I hate to keep coming back for help but!  (Asked vendor for return of 1st unit without chip, thanks guys) Soldered wires to SCL & SDA on unit with chip plugged into Flixi port pins 3 & 4.  But the I2C port stays black in flat info.  Spent hours reading posts etc and think I have setup right - Main port GPS etc and GPS works, Flexi port to I2C.  Magnatometer tab set Aux Only, I2C and of course says no aux mag found.  Calibrated onboard mag and it goes green

Hope I provided enough info,vwould appreciate any help

Ps. Ohm metered connections from GPS board to Flexiport connector both good

Verified SCL to pin 3 and SDA to pin 4 on Flexi
