no, you're going to be tapping wires. you don't want to cut them, just strip back the insulation, solder a new wire on, then tape securely, and reinstall in wire loom.

locations for wires can be found in a Haynes manual.

ahhh rats... thanks for the info!

Also another question say hypothetically i was to strip back the wire that unlocks the car and touch a wire that has 12 volts coming out of it on the unlock wire. Will the car unlock? Cuz that is how a keyless system works right? Or am i completly off?

some systems are negative trigger, so the wire is pulled to ground, not driven to 12V. which it is depends on the year/make/model of the car.

alarms should be installed by certified and trained personnel. you can damage the car's electrical system if you connect wires incorrectly. professionals have access to vehicle wiring information, tap locations, etc.

an alarm just makes noise. a security system prevents the car from being stolen. only a professional can install a security system.

I did my own security system. I spent two weeks reviewing schematics and the installation manual to pre-plan all of my connection points. I spent a weekend - about 20 hours, installing the security system. a lot of that time was disassembly/assembly of the vehicle so wiring was hidden. time was spent at every connection point to ensure it would not fail.

It takes a good deal of time to properly install a security system. just hiding stuff under the dash is not adequate. poorly made connections can fail and leave you stranded.

you can just use a BOSCH relay if you want to convert +12V trigger to negative trigger. cheap and easy.

you connect either positive or negative door switch. not both. for Honda, it's negative trigger.

Consider the Honda Security kit, which includes a harness that will do the right thing.

If this isn't done right your car may be immobilized, or worse.

Here's a link, expensive thought:

I moved this from my visitor message. that's not the place for the discussion. a PM maybe.

correct on both counts.

hazard lights to parking lights wire (to control lamps for arm/disarm/alarm

negative door switch wire to door trigger wire.

the other guy needs a relay because he isn't using an alarm but a circuit to control the doors. most alarms include both positive and negative door trigger wires - you only use one.
