Needed to replace the cooling fan relay of my 2007 Classic (T2506040). was sent T2507727 as "part interchanges with part T2506040' , which it doesn't? Am I missing something here, or just sent the wrong part? Thank you in advance.
Think I have figured it out. the 4 pin (T257727) replaces the 5 pin (T2506040), BUT, lacks the protection diode/resistor for the ECU. Maybe better getting a protected 5 pin from Autozone.
