What is the part number of this Ford wiring repair kit instruction sheet?

How much insulation should be stripped for the solder splice?

Strip 1-1/2" of insulation from one wire being spliced (Wire #1) and 3/4" from the other.

What type of solder does Ford specify for wire splices?

Rosin core mildly-activated (RMA) solder, applied after twisting the wires together.

How is the heat shrink tubing applied to the repair?

Slide the tubing at least 1" away from a stripped end before soldering, then position it evenly over the repair and heat its entire length with a shielded heat gun until hot melt appears from both ends.

What does the sheet say about kits with 14 AWG and larger wire?

Once wire lengths are sized so repairs can be staggered, strip insulation 1/4" from the wire on the pigtail; strip length varies depending on the gauge of the butt splice and wire harness (the table is cut off in this scan).

This document is Sheet 1 of 2 of the instruction sheet for a Ford Motor Company Wiring Repair Kit, part/sheet number SK 3U2J-14B475-AA, copyright 2003 Ford Motor Company, Dearborn, Michigan 48121 (dated 5-03). The photographed sheet sits atop the kit's plastic packaging, which contains black wire with a heat-shrink splice. The visible portion covers a solder/heat-shrink wire splice procedure: strip insulation 1-1/2" from Wire #1 and 3/4" from the other wire, slide heat shrink tubing at least 1" away from a stripped end, twist wires and solder with rosin core mildly-activated (RMA) solder, bend Wire #1 back straight after cooling and inspect the joint, position the heat shrink tube over the repair, and heat the full tubing length with a shielded heat gun until hot melt appears from both ends. It then begins instructions for kits with 14 AWG and larger diameter wire (crimp/heat shrink repair): strip 1/4" of insulation from the pigtail wire, noting strip length varies with butt splice and harness gauge per a table that is cut off in this photo. A reader learns Ford's approved splice technique and the kit part number.
