I am having to replace my engine wiring harness due to fire. Junk yard has harness but for 1997 and mine is a 1998 Dodge RAM 1500 Quad Cab 4X4. The first 8 Vin numbers are the same. The only difference is the 10th digit which is the year. The tag on my wiring harness is 18 years old and unreadable. Was there a big difference with the year and will the wiring harness work?
