Hey guys, looking for some help on some wiring issues Im having. I've got a '03 CTD motor (had NV5600 behind it), and dropped in 48RE. Rounded up a '04.5 ECM and wiring harness to work with the '03 CTD and 48RE, but the problem I have run into is bulkhead connector, "C-219", as it's called by the CTD Service Manual for '03 trucks. The problem? Well, the '04.5 engine harness doesn't have the exact same wiring/pin locations as the '03 under dash harness. I have all the pin locations and what not for the under dash '03 side. What I need is the pin locations for the engine side of "C-219" for an '04.5 model CTD.Thanks

Why use the 04.5 ECM? You could just use the 03 ECM.

You should be able to find what you are looking for in the Service Manuals.
