HO Santa Fe 4-8-4 Harness Fix -- Need parts!

[part throttle]

Hi guys,

I have a 4-8-4 for Santa Fe that needs a new harness.  The "parts" page does not show they are available for that engine.  Every time I try to fix these with soldering, it gets worse than it was before. 

Does anyone know how to fix these themselves?

I tried signing in to the service page to ask but it hangs up and will not let me log in.

Mr. Bach-Man can you help with this??

Best regards,
Part Throttle

Dear Part,
Call the service department on Monday.  They'll be able to help.
Have fun!
