Guys, I found the solution:

You need to find the file "prototypes/entity.lua" inside .The zip file of this mod.

Next - find these lines

circuit_connector_sprites = circuit_connector_definitions["heating-tower"].sprites,
circuit_wire_connection_points = circuit_connector_definitions["heating-tower"].points,

And change on this line

circuit_connector = circuit_connector_definitions["heating-tower"],

Enjoy~

Hi. I got randomly given collaborator status on this mod, and just pushed an update which addresses this in a slightly more comprehensive manner:

circuit_connector = circuit_connector_definitions.create_single
(
    universal_connector_template,
    {variation = 27, main_offset = util.by_pixel(15, -22), shadow_offset = util.by_pixel(20, 2), show_shadow = false}
),
