I ended up curling the wire around, clipped the ring into a C shape, and putting it between the metal bumper and the metal bolt that goes into it...worked like a charm.
I added an $18 set of "blazer driving lights" (I know..cheapo..but for a '91 ranger, nice lights don't seem worth it), aimed them today, and found that they work much better than I expected. They actually do a better job of illuminating the road in front of me than the stock headlights. I drive at night daily, so I figure it's a good investment in my safety. The only major discrepancy is that there was no relay in the packaging. I want to put one in later on so the driving lights will turn off, when I turn off the truck (independent of if the switch for the lights). It'll also keep too much current from passing through the switch.
For what I paid, I'm quite pleased...thanks guys.
