Here is the problem. If you already have an EGT sensor and want to use it to measure fuel pressure for example, you will also need to purchase an ANOTHER pigtail, part number 98605, which will not be apparent until you open the box and see what is missing. Part that adapts to the EAS connector. To top it off, part 98605 costs ANOTHER $149, which accounts for about $15 for wiring and adapters. To a certain extent, EAS cheats the customer here.
