Here's a very basic Tab for the song I wanna know what love is. 
Its simplyfied and therefore not the version recorded on cd.

          C                   Em

Em          D            G
Now, this mountain ...
       C                     Em
              ... upon my shoulders
            D                 G
Through the clouds ...
               C               Em
It keeps me warm  ...     .. colder
C      Am                 D            C
In my life ...
         Am            D       C
I don't know  .....  face it again
            Am         D         C
Can't stop now ...        ... so far

          C            Em
A little time ...

I've got nowhere ...
               C               Em
               ... has finally found me
C      Am                 D            C
In my life  ...     .... heartache and pain
         Am            D       C
I don't know if I can ....
            Am         D         C
