2nd Gen Non-Engine/Transmission ABS Wiring Harness Pigtail

[NLofton]

Well after searching through all the posts on 98 2500 4x4 speedo and brake light problems i finally tracked down my problem. I changed the abs sensor on the rear diff. and the brake light switch. Neither fixed the problem. Had a friend watch the speedometer while i wiggled the wires from front to rear, found a bad spot right at the rear end. My question is does anyone have a part # for the short harness about 6'' long, on the rear abs switch. Thanks for any help and this site is well worth the money.
