need advise on type of doorlock actuator to buy?

my car is a 1990 honda crx si, which has manual door locks,   i have a clifford arrow 2 alarm system with 2-button remote and the manual for it shows it has wires coming out of the brain for (door lock & door unlock), so i think it is already set up so its ready to easily add power door locks ?      but i can double-check and look at the brain and see if it has relays or not ?     or at least make sure it has the color wires meant for the door locks like it showed in the wiring diagram of the manual.

i'm just sick of fumbling with keys and stuff, and want to add power locks since after reading more about it, its easier than i thought.

i understand how to install them and have a few good detailed write-ups with pics for installing them on my car, which ill use for reference,    

i just need to know what do i look for in buying an aftermarket door lock actuator ?     does it just have to be a 2-wire type ?

does it have to be one titled "for honda . . .",    or is a universal one fine ?        from reading, a lot of people said the aftermarket ones from ebay work fine,   i just want to make sure i choose the correct type to work with my car exactly?,    so i just wanted to see if anyone knew what i need to put in the search on ebay when looking for them ?

thanks for any help you can give me

If you intend to control them from the alarm only, you will need a pair of relays or DEI 451M with two wire actuators.
If you intend operation from driver's door key as well, you'll need a 5 wire in the driver's door and a dedicated timer relay from Spal, MES etc.
The 451 mentioned above isn't needed.
Don't even think about 5 wires in both front doors,they will work against each other giving you installation nightmares.
The Arrow has two lock wires, program them as NEG. Long time since I worked on an Arrow ll but NEG may have been the default, test.

thanks for replying, you helped me in the past about cutting the brown wire from the brain to disable the parking light flash feature, which i did and fixed it.

i was assuming the clifford arrow 2 came with its own door lock relays,    but i just noticed reading the features in the manual, that it said "Remote Door Lock Capability",   but had (some vehicles require optional relays),   i missed that part before.       

so how do i find out for sure if i need to buy relays or if it has them already ?       

i did'nt understand what you meant about operating from the drivers door key ?,    did you mean being able to lock both doors with one button on the drivers door ?       

mainly i just want to find out what i need to buy in order to put power locks on my 2 doors that work with my clifford arrow 2 and remote,    i'll get all the install details later, after i recieve the parts and get started on installing them.

You'll need relays or 451M relay module. Default is low current NEG.
Yes or key.
I've already told you what you need and given you the options:-
Operate from alarm only-
2 X 2 wire actuators plus fixings and wiring
1 X 451 module or two relays.

Operate from alarm and driver's door-
2 door relay kit, one X 5 wire 1 X 2 wire fixings wiring plus dedicated timed lock relay.

thanks alot for your help,   thats really what i was wanting to know, just what i needed to buy in order to do what i wanted,

so your list of my options all summarized is perfect, so i can just see it all in one place,   and know what to search for when buying the parts for it.   

your signature said to first search and do research before posting,   and really i have done that ,   but just did'nt have any kind of confirmed answer of what type of actuators to get,   
i was reading write-ups with people doing power door lock installs on honda crx's, and they said to use a 2-wire actuator, but thats it, and some said to use oem actuators too,    
i looked at the clifford arrow 2 wiring diagram and manual but did'nt tell me much from that,   

but now i understand that the door lock relays are something thats usually a part of the car,   so if a car like mine did'nt come with power door locks,   then it would'nt have door lock relays in the fusebox,   and thats why i would need to buy those seperately, cause before i was under the impression that the door lock relays were inside of the brain or something?   but i was wrong about that.

thanks again Howie for your help,

That vehicle is too early to have a body control module.
On post 2000 Hondas, yes.
Post 96, UK build, post 2000 Japan, all had OEM motors.

Out of interest, pre-2000 CRX (UK) and most Japan build had a switch in the driver's door and a motor in the passenger door. If you can operate the passenger door by key locking the driver's door you only need one motor. Let me know.

before making this post, i was using a write-up on how to install door lock actuators on a honda crx, but it had me more confused,     cause this is how he described how to hook up the DEI 451M :

"The 3 wire harness from the 451m replaces the 2 wire/3pin stock harness that comes with your alarm. There are 5 thicker wires that then come out of this relay.

GREEN/ blk = +12v lock
Blue/blk = +12v unlock
BROWN / blk = to switch, not used
WHITE/ blk = to switch, not used
Violet/blk = to trigger wire (in this case +12v)

You will also still need to utilize 2 basic 4-pin SPST (single pin single throw) relays. You can pick these up at autozone,advance,etc. These are used to throw a ground to one wire (or the other) of the actuator depending on which wire is being energized with +12v. (If you're lost, this will hopefully make more sense in the picture below, or maybe not lol)

The DEI 451m converts the negative pulses from the brain into positive pulses. it also ups the amperage so that the actuators can be ran off of the 451m unit. when you hit lock the green wire pulses +12v, and when you hit unlock the blue wire pulses +12v. So logically you might think hook the blue and green wires from the dei unit up to the blue and green wires of the actuator. Now this would work fine except for the fact that when one wire is +12v, the other wire does not become a ground. obviously it has to do so in order for a circuit to be completed and for the actuator to do something. by wiring in the 2 extra relays it provides a ground only when its needed."

As follows.
Thin green to grey/orange on Arrow, and blue to grey/green on Arrow.
Thin red to 12V+ constant Join to the Arrows red power lead.
GREEN/ black and blue/black to motor wires.
BROWN / black and WHITE/ black to ground (earth).
Violet and violet/white to 12V+ constant, fuse box etc.

Forget everything else you wrote.
In fact if the vehicle does have a motor in passenger door, you won't even need relays! Let me know about that.

i know its an older car and lacking a lot of features which most cars today come with standard,   but i am aware how the UK, Japan and other countries had more accessory options available for the CRX, like power locks or windows, mirrors, heated seats, etc..., plus they had the CRX SiR, etc . .,     and alot of us in the U.S. are frustrated how we just got the basic CRX with no options available or any of that cool extra stuff,   but the only explanation is they were just trying to compete with the other cars selling in the U.S. which were basic models too, so they thought they would sell more that way.

so you were saying that if i wanted to be able and turn the key in the drivers door to unlock both the drivers and passenger doors at once, i would just need one motor?,    when you say motor, are you refereing to an "actuator"?       

i really did'nt want to have to turn my key into the lock cylinder of the doors anymore, and just wanted to have simple keyless entry where i unarm the alarm remote and it unlocks the door,   and then also locks when i arm it.     

i have locked my keys in my car a few times recently, like after it fell in between the seats and i thought it was in my pocket and just shut the door locked,     or leaving it in the ignition and thought it was in my pocket already and closing it,   and i never pay a locksmith and instead rely on my friend to help get in my car,   and lately the easiest way i've found is getting in through the sunroof, but this last time the guy almost broke it, so it was frustrating especially since i just have been doing a lot of work to my sunroof recently and got it all working good again, but now have to mess it all up trying to get in the car through it to get the keys !

if i have keyless entry,   then it seems like it would be easier cause i would have to press the arm button in order to lock the car, as opposed to having the latch on the inside of the door in the locked position and closing the door, but then realising the keys are inside the car, so it should solve that problem for me having the power locks.

Yes, the UK version only had a motor (= actuator) in the passenger door, therefore just try and see if working the driver's lock slide or key also operates the passenger door lock, otherwise wire as I showed above.
One has to be careful, major Civic build = Japan, US and UK plus French and Chinese versions.
Up to 2000, Japanese Civic was 1" narrower and 3 door or Coupe only, all CRX were Japanese build but as you said quite rightly many local options.

Japanese and US cars had a "primitive" lock system where you could lock the door with the car open and "slam lock it.
All Euro cars have a mechanical interlock, i.e. if the catch at the lock isn't thrown, i.e. thinks door is open they won't lock
