To get distinct highlighting for each field, try the following:
syn match pipeFirst /^[^|]*/ nextgroup=pipeSecond
syn match pipeSecond /|[^|]*/hs=s+1 contained nextgroup=pipeThird
syn match pipeThird /|[^|]*/hs=s+1 contained nextgroup=pipeFourth
syn match pipeFourth /|[^|]*/hs=s+1 contained nextgroup=pipeFifth
syn match pipeFifth /|[^|]*/hs=s+1 contained
hi link pipeFirst Constant
hi link pipeSecond Identifier
hi link pipeThird Statement
hi link pipeFourth PreProc
hi link pipeFifth Type
and so on ... and replace the "pipe" prefix with a more appropriate name ;)
