TCC Lockup 98 Tahoe I have a 98 Tahoe that I'm dropping a lq9/4l60 and in my harness for PSI conversion there is wires that say tcc lockup. The brake switch they sent me for the tcc lockup is a different style than the factory one in the truck. What do I hook those wires up to?

The switch really doesn't matter. Since you're swapping it into a late model truck, it already has a brake switch installed. All you'd have to do is hook up the the existing TCC brake switch wiring to the PSI harness, and remove their switch. Technically all the PCM is looking for is 12v or not, and since you've already got a switch and wiring installed, you don't need to reinvent the wheel.
