On my '96, there were two clips, both on the stamping for the motor mount. One is visible from the top, one from the bottom. The bottom one is in a rather awkward spot, as the sway bar is in front of it - visible, but tricky to reach.

I had seen the clips advertised as an available part, and hadn't paid much attention, thinking I could use good old zip-ties if needed, but in fact they wouldn't work very well.

No, I didn't use a universal sensor - I asked about this when speaking with the parts house staff from whom I bought the part, and they said that they hadn't seen them work out well. Apparently, mechanics had difficulty getting the connections to stay over time. From the pics, it also looks like you have to commit to the universal sensor. All in all, the extra money seemed worth it to use the factory's original plan.
