Wiring harness

[DVT873]

IF you do this get the VIN of the truck that you are getting the gauges, sensors, etc. from. The body computer program Diamond Logic Builder (DLB) lets you pull down the Body Computer (BC) programming for any VIN including all the settings. With DLB you will be able to make the changes. I know that for the OE version you have to pass a simple test and set up a username and password to be able to make changes. I have no idea how the bootleg software would work. With DLB if you make changes it uploads them to the mother ship automatically as soon as DLB has internet access.

You will likely have to overlay the wiring from the sensors to the BC because Navistar wiring harnesses are built to VIN so the wiring is only there for the features on the truck as built. It has been that way since the start of Next Generation Vehicle (NGV) back about 2001. Not like the old days when there were often unused circuits.
It looks like the sensors will go to the BC and then CAN J1939 over to the Secondary Instrument Cluster.
