What wires go where?
The shock sensor, siren and main control unit are proberley best located on the firewall in the engine bay. You could put them in the dash but theres not much room and a K10 dash is pretty open.
The microwave sensor should be located under the front seats as close to the middle of the car as possible, or possibley inside the centre console.
Ignition start - I guess this is to do with an immobiliser and is used to break the circuit with a relay, need some more specific info on this.
Ignition acc (red) - can be found easily in any car at the back of the car radio.
Interior light - would have to look in the haynes manual to see what colour the cable is proberley runs to the fuse/relay block on the drivers side. You could get to it by the door switches.

UPDATE: must be for remote engine start (would not bother with it on a K10, proberley wont work that well)
RPM - To make sure it knows when the cars started, dont know anything about this as I dont have a rev meter on mine.
Handbrake light - To make sure that it will only remote start when the handbreak is on. This is easy to locate by removing the centre console, just a few screws very easy really. Sould be an electrical cable that connects to the handbrake switch.
---------Still not sure about this:
Alternator - This is either to do with provideing power to the alarm (+ve to battery) or for connecting to any accessory that you dont want to set of the alarm when its used, eg a fan. This could also be for a battery backup siren, if so you could just wire it onto the battery (+ve).
Opinion & Installation
To be honest you should be able to fit the alarm without removing your dash board. The easiest way to hide the cables is to put them under the carpet, in routing the microwave sensor you may need to make a tiny slit in the carpet to get the cable from underneath it to under the seat. If you remove the door trim you find its easy to put stuff under the carpet.
Most of the wires you will need will run into the back of the radio, to the car body, the battery or around the ignition switch. Take each wire one at a time as long as you dont power up the alarm you dont even have to do it all in one sitting.
Serious alarm fitters aim to make every cable very hard to get to and do not make them colour coded or distinguishable from the original wiring loom. But the install is only as strong as its weakest link (could give examples of obvious weak links but proberley shouldnt). Hopefully a thief would not bother trying to steal a K10 if its got an alarm/immobiliser anyway.
I am by no means an expert, just knowledge from personnel experiance. Heck maybe someone on here fits alarms for a living and can advise you more.
Essential tools & top tips:
- Electrical tape - to cover exposed wires and hold stuff in place.
- Electrical connection blocks - simple way to join wires just screw them in each side, cant really be used under the carpet tho.
- Screw driver or other sharp point - for making small wholes in the carpet or any rubber grommets to pass wires into the engine bay.
- old coat hanager - can be used to navigate wire through tight or difficult spaces.
- Wire cutters, strippers and electrical screw driver
