hey. im assuming you mean there is one orange wire coming from the wiring loom of the keyless entry module??
the purpose of this wire is to make the indicators flash when you lock/unlock the car. You have to hook it to the indicator wires on the car. If you have a test light, hook it to earth, turn on the ign and put your right indicator on. Probe the wires coming from the indicator stalk. When you pick up the wire that is flashing on and off with the indicator you know this is the right hand indicator wire. Do the same thing to find the left hand one. Once you have both wires it becomes a bit tricky.
Because there is only one indicator wire (orange) from the module you will have diode split it to be able to hook up to both indicator wires on the car. You can use two 1 amp diodes although I'd probably use two 6 amp diodes just to be safe. you will need to twist the BAND end of the diodes together and hook this to your Orange wire from the module. Then hook the other end of the diodes to the seperate indicator wires on the car. The purpose of the diodes is to keep the left and right indicators seperate. If you didn't use them and just hooked up to both, whenever you put on the right OR left indicator, both lights would flash, like as if your hazards were on. The diodes may have come with the module or else you can get them from Dick Smith etc.
sundeep wire it to your hazard switch, this avoids messy and inproper diodes which can fail if the reverse breakdown rating is wrong and which can when not done properly cause damage to the flasher unit such as fast flashing etc. Also why waste money on diodes and wiring it up when 2 inches before that is a switch where its already done.
sundeep i took the liberty of taking off the plastic casing around the ignition/steering wheel and found out the hazard switch is an integrated part of the turning signal switch and doesnt have one wire which can just be loaded to make the hazards flash, it can be done with a soldering iron, and some wiring and maybe even some electronics but its certainly not worth it.
SPHELL, or brent, or whoever suggested it, had the better idea on this one....just make sure they are rectifier diodes and not small signal diodes (ask the person at dick smith for this) as the rectifier diodes have good reverse barrier protection (as they are used in 50Hz power supplys 24/7 often)
