2. Once component bracket (P/N 755017A4064) is accessible, use a No. 1 Phillips head screwdriver to
loosen the hardware securing all wires to relay 1A14K1. Tag each wire for reassembly identification.
3. Use a No. 1 Phillips head screwdriver to loosen and remove the mounting hardware that secures relay
1A14K1 to component bracket (P/N 755017A4064).
4. Reconnect the new relay to component bracket (P/N 755017A4064) in the reverse order of dis-
assembly, making sure the original wires are attached in the same orientation as before disassembly.
