Will this work for hooking up a pair of hella horns on my taco?

I got this for my subaru when I replaced the oem horns with hells horns.

I want to do the same thing with my taco, but wasn't sure what kind of plug the horns have. Will this wiring harness work ok, or does it need different ends for connecting to the factory horn plug? The harness uses a connector like this...

to plug into the factory horn wiring.

 

yes the will work but with the hella horns you also need a ground to.

 

There's a ground on the harness, and one to each horn. Do I need another ground?

 

bump for clarification

 

bump again.
