I2C pull up- GR Lychee

Question

Hi all 
 Jumper connections 
 How to short JP3/JP4 ? There is no exposed jumper connector, so do we need to permanently solder ? 
 I want to use I2C lines for communicating sensor data to the Controller. 
 
 So, How to short JP3/JP4 ? Is it permanently to be soldered or any idea of shorting it when required ? 
 Also , 
 Pullups 
 Unable to 
 located R43/R45 on board which says two.seven k ohm, Is it internally pulled up or 
 should i use the same value resistors for external pull up ? 
 
 Thanks,

Hey, 
 
do we need to permanently solder ? Yes Once you solder it, it will be permanent, there is no separate connector to short between these jumpers 
 
& Yes R43/R45 are internally Pulled Up so no need to add any external register for same value (Near JP3/JP4 Jumpers, the last 2 registers are R43 and R45)
