Sure:

Code:
awk '
  NR==FNR{                       # When the first file is being read (only then are FNR and NR equal) 
    A[$1]=$3                     # create an (associative) element in array A with the first field as the index and the 3rd field as value
    B[$1]=$2                     # create an (associative) element in array B with the first field as the index and the 2rd field as value
    next                         # start reading the next record (line)
  } 
  $2 in A{                       # while reading the second file, if field 2 is present in array A (we could also have chosen B)
    $6=B[$2]                     # then set field 6 to the element in array B with the second field as the index
    $14=A[$2]                    # and set field 14 to the element in array A with the second field as the index
  }
  1                              # print the record (line)
' FS=\| OFS=\| file1 file2       # Set the input and output field separator to the pipe symbol and read file 1 and then file 2

Hope this helps...
