ISM 15-pin Inj. Harness

[DieselDan]

Has anyone had a problem with the external 15 pin injector harness? By design at least on this application it seems to be piss poor. The plug where it goes into the rocker cover (external side) doesn't leave a lot of room and seems inevitable that the wires get twisted/bent.

Last time this happened and I had injector codes I succumbed to the Cummins dealer telling me I could not buy just the 15 pin connector and pins. Therefore ended up buying the entire harness. Does anyone have any idea if it is indeed available separately?

Thanks in advance!
