Which hook to use to add fields to BO customer account in PS 1.7

[derykr]

Hi,

 

I am trying to use the hook, displayAdminCustomers, to add fields to the admin customers page in the back office, but nothing seems to be happening!

 

I have successfully changed the front office using the hooks ActionCustomerAccountAdd and DisplayCustomerAccountForm in my module, but I cant seem to find the equivalent for the back office.

 

Any pointers would be appreciated :-)
