If the Celta is a 4 passenger car, it should come with a hitch installed..
I got a wiring kit for my Ford Esc for Xmas. It was a surprise.
I wasn't going to order one, because Ford doesn't install the three relays
you need in the fuse box..
Then, I found the relays on-line for $8 each.. Still I procrastinated,
because I could not see any metal contacts in the relay sockets...
Soon after xmas, I finally found out the bad news (on-line trailer store),
Ford failed to install the contacts under those three light control relays.. (Cost of copper?)
My kit is worthless..
