@Nitrogen is correct. I did post a thread on it as I picked up a hitch from a salvage yard off of a Liberty for $25.
It was a close fit, but I ended up with the same issue of the spare not fitting. Ultimately, I scraped the idea and bought the correct hitch and wiring off of Amazon.
After all was said & done I had a perfectly working hitch for around $150.
