No horn attached!

Hi all looking to see if anyone can help me. I’ve recently bought a 3 spoke steering wheel for my NB as the car came with the awful rubbery 4 spoke wheel. I bought the 3 spoke wheel off eBay and I’m rather annoyed that it hasn’t come with a horn connector such as the one in the attached photo (of the OEM 4 spoke). Has anybody had this same problem and can anybody suggest a fix? Thanks. :smile:
