I think I found it, thanks!!
The Modernized TADS/PNVS program replaces six of the current LRUs with new ones. They are the PNVS, PNVS Shroud, NSA, BSM, TEU, TPS, and PEU. Also, slight modifications are being made to other components to address other maintenance drivers identified over the years. The DSA and Laser are not being modified. The modernization includes moving to a two-level maintenance concept for the new LRUs. The Line Replaceable Units (LRUs) were being designed to allow smaller Line Replaceable Modules (LRMs) to be fault isolated and replaced, rather than the entire LRU.
The basic configuration and outer look of the M-TADS/PNVS is almost be identical to the current system. The PNVS shroud looks different, because it now has two sensors, the new FLIR and an Image Intensification Sensor (basically a built-in 18mm NVG tube). The pilot is now be able to switch between the two sensors and to fly using the one best for the existing conditions. Complete provisions were included to eventually fuse the two images. The shroud is broken into two LRMs (shroud and window), making removal much simpler. The current W-10 harness is being replaced with a two-piece design. The new FLIR has a much better image quality than the current system. It has 4 pixels across and 480 pixels down (4x480), compared to the current common module 1x180 configuration. What this means is that the system has much better wire detection and marginal weather performance, at least 20/45 visual acuity, compared to the previous 20/80
