I have a two sip trunks with the following dialplan:
TRUNK A:
exten => _0004XX.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _0004XX.,2,Dial(SIP/${EXTEN:1}@AAAA,,tTo)
exten => _0004XX.,3,Hangup

TRUNK B:
exten => _0004XX.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _0004XX.,2,Dial(SIP/${EXTEN:1}@BBBB,,tTo)
exten => _0004XX.,3,Hangup

When I load leads I load it with the following format : phone_code: 0004X
in campaign dial prefix is : X

How can I setup for certain extensions to goes to trunk A and certain extensions to goes to trunk B ?

With that setup, you can't. The extensions you loaded conflict with one another and only one of them will actually load. There must be a difference in the extension to have two different call paths.

Start here: HOW do you want to decide which calls go to A and which calls go to B? Random luck? Phone numbers that will result in a sale should go to A and phone numbers of deadbeats should go to B?

The system isn't psychic, there must be a way to differentiate between them ... if you tell us in English, we can tell you in "Asterisk Dialplan" how to make it happen!

I want to extensions 8001 and 8002 go to trunk A and extensions from 8005 to 8020 go to trunk B ?
All phone numbers will be dial from lists which is load with phone code 0004X

Extensions don't initiate calls in Vicidial. Calls are generated by Campaigns or users in campaigns. The campaign dial prefix determines the carrier in use if properly configured.
