Here is the wiring diagram for the 1999 Accord. The vehicle may also have the Immobilizer chip in it. You will have to bypass this in order for the remote start to work properly. IT's quite simple with the proper module:

Notes:
NOTE: This vehicle has an immobilizer system that needs to be bypassed when adding remote start. Use PKH2 or TBKII modules *1 Must interrupt the wire between the keyswitch and the fusebox, not between the fusebox and the starter, to keep the check engine light from coming on. *2 Use BLACK/ white for lock and GREEN/ red for unlock on LX models without factory security. These wires are located in a two pin gray connector by the front of the drivers side fuse box. *3 in a green 20 pin connector. *4 yellow on the EX and lt. GREEN/ red on the LX *5 located in the same plug as the door lock wires. Also found in a 14 pin green plug at the drivers fuse box on the EX model. *6 Only available on the EX model. *7 In a green 4 pin connector. *8 Above the hood release in a gray 18 pin connector. On the DX & LX models, also found in a 2 pin connector behind the drivers fuse box. *9 Arms and disarms with the door locks on the EX models. The LX models arm only with the factory transmitter. *10 On the EX the wire is located at the drivers power window switch, on the LX the wire is at the keyless/security unit which is attached to the drivers underdash panel. *11 The tach test connector is located behind the battery on the 4 cylinder, and on a bracket attached to the drivers side strut tower on the 6 cylinder motor. The tach test connector is a white 2 pin connector, and may be covered by a black rubber boot. *12 Located at the first plug on the ECM, it is a 32 pin gray plug. The ECM plugs can be accessed by pulling up the carpet on the passenger side of the center console. There are 4 plugs total. *13 On the EX models it is in a green plug next to the passenger side fuse box. On the LX models it is at the keyless/security unit, if equipped, which is attached to the driver side underdash panel.
