what adapters do i need to retain the factory oil pressure and temp gauges in my 93 k2500 the engine is out of an 04 yukon. id really prefer not to drill and tap anything since the engine is already in the truck and it seems it would be a pain to do. the adapter i saw for oil pressure eliminates the 5.3 sensor dosnt the 5.3 ecm need it to work poperly?
Good question and on the subject does any one know the drill and tap size for the temp sensor? I belive its 3/8 npt but I am not sure

Tap the block off plate above the oil filter to 1/8" NPT and install the oil pressure switch there. There should be enough wire in the harness just take the tape off of it. You can get a temp sensor adapter from Welcome to Street and Performance
Hope this helps.

so you do need to run both oil pressure sensors?

Yes, one runs to the pcm and the other from your old engine will go to your gauges. this is the same on the temp and oil pressure.

ok seems red told me I only need one, I broke the one off the 5.3 and he told me to just drill and tap the broken piece for the one off my 5.7
