I buy a decent amount of stuff from a local International truck dealer parts debt. Never had an issue.
Today I tried to buy a new FICM harness for my 2003 ( IH# 1843796 C92) and the parts guy said it was restricted on his computer, he couldn't even buy it. He also said that harness on a school bus VT365 would be different.

I'm a little curious about the validity of the school bus statement, but I'm definitely seriously curious to know if anyone out there has gotten this part using this part # through International.

 

I haven't been able to buy any harnesses through international even having the correct part numbers. Most aren't even available. The harness you're looking for is probably specific to a Ford chassis and that's why it's restricted. That's my best guess anyway.

 

Buy it on Ebay and save yourself some money.
