my friend had a predator tuners, he use that to disable his rear o2, can he disable my too ? or that just for his car only ? he had 98 gt just like I do too.
 
Here's the directions to make your own MIL eliminators:

That design shouldn't melt. The exhaust shouldn't be hot enough to melt solder back at the second set of O2 sensors. You could make that with a tiny PCB and wrap it in heat shrink tubing. It's meant to be done by modifying an existing O2 sensor.
