I finally got the conversion parts to convert my 00 civic DX HB from manual windows / locks to power. This morning I started to pull the fuse box apart to lay down the new floor harness. While down there I wanted to install the Keyless entry receiver box. I checked the manual and I have checked on line but can not find a sure answer. Where is the plug for this unit? Is it part of the floor harness or the dash harness? Do I need to replace another harness to have keyless entry? I know that the 96-98 receiver unit was built into the radio and changed in the 99-00 to have a separate control unit. I have pulled all the wires down in the kick panel and can not find a plug for it. I dont want to buy an alarm I just want to get what I bought working. I have found tons of tutorials on the 96-98 but none for the 99-00. If anyone knows or can help me. The manual says all models from 99-00 should have the plug but I cant find it. PLEASE HELP ...thanks in advanced.

 

The 18P connector for the power locks control unit located behind the driver's kick panel is part of the main wire harness. Many (not all) of the 18P connector's wires run to 20P C401 on the main wire harness under the dashboard. C401 connects to C555, which is part of the floor wire harness.

 

Ok great this gives me the definite answer I needed. I guess my next question would be is there a situation where the car would NOT have this plug? I believe this car was a DX auto trans converted to manual if that means anything. Also I found the power lock assist box which is between the steering wheel and the radio / HVAC control unit under the dash. I am just having a hard time finding this one plug that should run down the harness right next to the footrest. I have no wire there... I hope someone can help I can post pictures if that will help.

 

Not sure what this^ box is, but an 00 Civic DX is unlikely to have a power lock control unit. If you had one, it would be behind the driver's side kick panel.



I think that, at the very least, you need to go to a junk yard and buy a dashboard main wire harness taken from a 99-00 EX, LX, or HX Civic.

 

the connector for the door lock module is on the cabin harness, which kinda sucks to have to replace the whole harness behind the dashboard.

 

when i did power windows and keyless entry for my 99 dx hatch i used a floor harness from a 99-00 ex coupe. i did not have any plug that would plug into that power lock assist. a buddy of mine helped me do a relay and then the doors worked like factory. hope this helps.

 

Did a whole lot of research and looks like on the 99-00 you will actually have to replace the dash harness to get power windows and power door locks. I will probably leave this for some other time I am just happy to have power windows. Now just have to sell the power to manual conversion. Thank you all for your help on this crazy project.

 

I am revisiting this as I have been studying the repair manual like crazy. Looks like power door locks are wired into all models except the GX version. The EX / LX have the security keyless door entry option only which I was looking for before but do not have. Now I just want to get my power door locks WITHOUT keyless entry to work. So I have all the parts for the power door locks but the only thing that happens is when I press lock the trunk light on the gauge cluster comes on. When I let go of lock it turns off. So I want to know where I should start my hunt to get this to work. The only 3 things I can think might be wrong with it is
1)Door harness (I dont see any broken or shorted wires might be in the plug that plugs to floor harness??)
2)The power door lock switch is bad.
3)The power assist / lock box is bad. (The one under the dash between the steering wheel and HVAC controls)

Any help is appreciated. thanks to RonJ@HT for clearing things up earlier!

 

Do you have a power dock lock control unit and the 12P connector in the driver's door?

 

I do not see that unit in my door or the plug for that unit that you mentioned in your reply. This is the unit that I have in my 00 DX hatch. Is this the same unit? From what I recall in all my research that in the 96-98 it was located in the door but on the 99-00 it was located in this location. If I am wrong then what door harness do I have and which one do I need? The current one I have was supposed to be from a 00 EX with power doors no keyless entry. Now I really confused.

 

No. You need the power locks control unit and the 12P connector in the driver's door. This is true for all 96-00 Civics lacking the keyless the option.

C448 is for the optional security system and has nothing to do with power locks.

 

it won't be in the door. the only 99-00 i've seen with the module in the door are canadian models. every 99-00 us hx/lx/ex/si has it in the drivers kick panel.

 

Incorrect. What you say above is only true for 99-00 models with keyless. See diagram in post #9.

 

the diagram says so, i've seen otherwise in person. even check the part # for the lock module.

 

Then all the models you have seen must have had the keyless system. Models with power locks but without keyless have the driver door set up shown in post #9. This is what the OP needs if he wants power locks without the keyless system.

 

negative. 99-00 hx and lx did not have keyless from the factory, but all you had to do was buy the remote from the accessory catalog.

the cars came with the same lock module as the ex/si, as proven with the same exact part numbers in the honda parts catalog. same goes for the drivers door harness.

99-00 hx and si

32751-S03-A23 WIRE HARNESS, DRIVER DOOR

38380-S04-A02 CONTROL UNIT, DOOR LOCK & KEYLESS

 

I hope you understand that you are contradicting yourself here^. The Civics you mentioned MUST have come with the keyless system installed if all you had to do is buy a remote, right? Again, for 99-00 Civics having power locks but lacking the keyless system, the power lock control unit is located behind the driver's door panel. I don't know which specific Civics came with power locks and without the keyless system but that's how they are configured. The service manual does not state that this was only true for Civics destined for the Canadian market, but I can't refute your claim. Again, the part numbers you list are for 99-00 Civics with COMBINED power locks and keyless. The OP is interested in knowing how to install power locks without a keyless system in his 00 Civic DX. Have you read the OP's question? Are you trying to answer it?

 

i am saying it did not come with the keyless remote from the factory. 99-00 hx and lx came without the keyless remote but has power locks, but since 99-00 have the keyless module and door lock relays are in the same unit, therefore it is keyless ready. the only other models available are the cx and dx, which did not come with power locks anyway.

in a long sum of words, i am saying he needs to either wire up some relays or make the factory module in the kick panel work by replacing the cabin harness or basically getting the plug and adding the wires in.

 

I also know this to be true, but this is off track with respect to the discussion here. Please read through the thread.

The OP is well aware that his 00 Civic DX has no power locks.

The OP is also aware of this^ and is now seeking a way to just install power locks. Please read through the thread. I informed him of how this could be done -- by installing a 96-00 power lock control unit and door wire harness in the driver's door. He may already have other components needed.

 

Wow this got a little out of hand for a moment. OK final answer. DX does not come with keyless entry option at all. If you want it to have keyless you go alarm or replace dash harness. If you do not have the keyless option the power lock control box is needed to make the system work WITHOUT KEYLESS ENTRY. So I just need to figure out if the car with keyless option (Donor car) has the plug for the power lock control box or do I need to find a door harness that comes with control box plug from different donor car. I wont be able to verify if my harness has the plug till I get home. Thanks all for all the help. I think we need to get an updated walk through that answers all these questions.

 

I think it was just a misunderstanding.

A donor 96-98 Civic with power locks and with or without the keyless system (or a donor 99-00 Civic with power locks but without the keyless system) should have the power door control unit behind the driver's door panel as well as the needed driver and passenger door wire harness and the floor wire harness.

 

Thanks everyone. I will get a moment in the next few days to pull my door apart and see if the door harness actually has the plug. I will report back with pictures and let you know whats going on. I think this needs to be added to the 96-98 instructions to clarify as I see a lot of people asking why their door locks do not work after conversion.

 

Let us know what you find. Some pictures would be nice.

 

Ok so I finally got some time to pull the door apart and replace the harness. Here is the info:

Door harness with out door lock control box. (Removed)
32751-S03-A220

Door harness with door lock control box. (Installed)
32751-S03-A203

I replaced the door harness without the power lock box with one with the power door lock control box. I still have the same issue. When I press the switch to lock the doors, the trunk open indicator light turns on. When I click unlock on the switch I get nothing at all. I Still dont know where the issue is. I do see on the dash harness that there was previously an aftermarket alarm installed but most of the wires were tapped into and not cut. I have gone over all of the wire harness's and cleaned up anything I could see was an issue. I dont know why the indicator for the trunk would turn on as they should not be on the same circuit. If anyone has any additional info I would appreciate anything right now...

 

Do you have a multimeter? It's time to do some voltage tests at the connector for the door lock control unit.
