Well this song is impossible to tab out correctly, it's all improvisation, on TWO guitars,
but I thought I'd give you a few things to start with.

The basic pattern of the song is a Dm / F / C7 / Gm / A layout.
Don't strum the chords, you get the best sound when you pluch three or four strings
together.

 Dm F C7 Gm A
e[--1----1------3---3---0--] _
B[--3----1------5---3---2--] \
G[--2----2------3---3---2--] |---> B,G and D plucked give the best sound.
D[--0----3------5---5---2--] _/
A[-------3------3---5---0--]
E[-------------------------]

I've tabbed out a couple of the fills used throughout the song. 
Applied on the basic pattern, you get this (quite accurate) version:

 Dm F C7Gm A Dm etc...
e[--1-------------1-----------------------1---]
B[--3--3----1-------1---1-5-3--2----------3---]
G[--2-------2---------2---3-3--2--2-0-----2---] 
D[--0-0-----3---3---------5-5--2------3-2-0---] 
A[------------3-------------------------------]
E[--------------------------------------------]
 \_________/ \_______/
 'up fill' 'down fill'

Vary by using the high e string a bit more, skipping a few notes in the fill 
or plucking a chord a few times instead. Which could look like this:

 Dm F C7Gm A Dm etc...
e[--1-------1-----1----------------------1----]
B[--3-------1---------1---5-3--2-2--2-2--3----]
G[--2-------2-------------3-3--2-2--2-2--2----] 
D[------0--------3--------5-5--2-2--2-2-------] 
A[------------3-------------------0-----------]
E[--------------------------------------------]

You get the point :) Now besides at the top of the neck there are some other places 
you can play around with the basic pattern. 
The e and B strings around the 10th fret are very suitable:

 Dm F C7 A
e[------10-10-10/12-10-8~~-(8)--10-8-----------------12-10-----------]
B[-(10)-10-10-10-------10~-(10)-----(10)-11--11--11-------(11)-10~~--]
G[--------------------------------------(10)(10)(10)-----------------]
D[-------------------------------------------------------------------]

To get back up the neck use this: (the same as the 'down fill')

 Dm F C7 Gm A
e[-------------------0-------]
B[-10-8-6-5-3~--1~-----3-----]
G[-----------------------2---]
D[---------------------------]

You can do the same on the G and D strings around the 7th fret.
Start with G[-7-7-7/9-] and you'll work the rest out easily...
 D[-7-7-7---]

Get back up the neck with D[--7-5-3-2-0~----2-0----]
 A[-------------3~-----3--]

After a while a trumpet enters to complete the Cuban atmosphere.
You can keep doing the basic pattern, but here's a small part of the 
trumpet solo to get you going on that one too.


e[--5~-------5~------6~-----------]
B[-----6-5-3----6-5-3---6-5-3-----]
G[----------------------------3~--]
D[--------------------------------]

And then the most difficult part: the solo. 
Kevin Futhey tabbed this one out already and I think it's very accurate.

e[-10--10~--8-10--8~---10-8---------------------------------8~-]
B[-10--10~--------10~-------11---------10~----------10-11-12---]
G[-----------------------------9-10-12------9-10-12------------]
D[-------------------------------------------------------------]

e[----------------------10-10-10-10-10/12-10-8--8~--10-8--------8------]
B[-6p5---8-8--[Outline-]10-10-10-10----------10-10~------11-8-11-11-10-]
G[-----7------[---A----]-----------------------------------------------]
D[------------[-Chord--]-----------------------------------------------]

e[--------------6-7-8/10-8\6----------------------------]
B[--------6-8/10-------------10-8-6----8----------------]
G[-7-7-7-9-------------------------9-7--10-9-7----------]
D[---------------------------------------------10-8-7~--]

Now back to the Dm / F / C7 / Gm / A scheme, and end on Dm.
