its actaully 555hw. You can pick up IMO the best bypass kit i have used which is the Fortin HONDA-SL3. Dont bother going with data kits because 1) you are simply wasting money and 2) that kit doesnt even work with your car. Its nice to use DATABUS systesm on NEWER cars over 2004. Since yours is a 2001, a RS/alarm and data will not work and it just cost more money. Just hardwire everything to the specified wires from the remote start to the proper wires on the vehicle and you should be good. Go with fortin, its cheaper but quality is amazing. the kit by bypasskits.com for honda is the
PKH34 which is a PITA to use. btw these are ALL DATA BYPASS so no keys required. Just one master to program.
the best bypass kit i ONLY use are
Fortin Electronics (
www.ifar.ca)
iDataLink ADS-TBSL-HA which is honda specific (
