Wire harness P/N 01-8742T3 is identical to early style wire harness P/N 01-8742T1 and will replace 01-8742 as the only change was the addition of Ref. 10 and 19 as a part of the harness. Wire harness P/N 20-1227T1 is used ASN 129-00007 and 130-00179 with the new audio alarm, 20-1216T91, which will sound, but the actual shutdown of the engine will not occur.

Superseded, Old P/N is not used any longer; the new P/N is to be used in All cases. Old P/N should be removed from existing inventory. It is recomended that the old part not be used under any circumstances.
The difference between these two component assemblies is that P/N 01-7132 contains only 1 relay (Ref. 49) while P/N 02-3721T91 has 2 relays (Ref. 49) on it. A/C Module Harness Kit P/N 35-1287T92 will convert the early style (P/N 01-7132) to the later style (P/N 02-3721T91) as well as provide the latest style wire harness for upgrading the A/C module.
