UK Civic and Toad Ai606

Hi Guys, I am installing a Toad Ai606 in a UK 98 Civic 1.8, all going well except for the power door locks. The car has factory keyless entry, which is functioning fine still. From what I have read here and on other forums Hondas use (-) pulse signal to drive the power door locks.

The first diagram is from the alarm installer manual and this is the configuration I am trying to use. The second is from the Honda service manual. The red and blue dots are where I thought I should be connecting to, but it is not working. The alarm is outputting neg when I arm and disarm the alarm, but I am obviously not connecting to the keyless entry system correctly. Any pointers greatly appreciated.

Thanks, John

The diagram is for a Civic, I just have them saved in my Integra FTP :)

I have been wiring up to the keyless entry contol unit which is behind the ashtray in the centre console in the UK civic. Here are some pictures. I have also posted a pic of the 5 wire connector in the drivers door. I am starting to think that using the 5 wire diagram on this site with the relays is the way I will need to go, as direct wiring does not seem to be working in this car?!? Any ideas how I can get this sorted? Thanks!

how are you testing, are you probing the wires and locking and unlocking the doors to see what ones go neg?

is it a GREEN/ red wire with siver rings you have been taping into

Yes, that is how I have been testing, I was wiring into the WHITE/ RED (PIN B1) and the YELLOW/RED (PIN B3) on the control unit behind the centre console, but it did not seem to be triggering the locking/unlocking. I was looking for GREEN/ red wire with siver rings as I saw that mentioned on lots of other installs but couldnt find it on this car.

Only thing that I can think of is that the temporary ground that I had attached the RED / BLK and RED / YEL of the Toad alarm to was not very well secured, I had just pinched the wires under a bolt on the centre console, it was showing ground on the voltmeter but may not have been solid enough to allow the alarm to pick up a good negative pulse, could that be it? The outputs from the alarm were also showing the negative pulse when arming and disarming the alarm when I tested them with the volt meter so I presumed it was ok.

I had just stripped back some of the wire and soldered the BLU/RED from alarm to the YEL/RED on the car and GRY/RED from alarm to the WHT/RED on the car in, I presume that is right as that is what I am understanding from the diagrams.

Cheers Joe, I considered the need to have the doors closed but the factory keyless entry still locks with the doors open, but even so I pushed the latch but it did not make any difference.

I didnt think of probing around with a grounded wire! doh! - I will try that again. It will probably be a few days before I get back at the car as I am back at work tomorrow, but if you think of anything else in the mean time, or anyone else has anything to add please do.

If I cant find a way around it after that I will probably just chuck an aftermarket actuator in the drivers door and use that. Thanks!

Ok I came home from work a bit early and had another bash at the locks. I didnt get too far though.

After doing that I decided to go probing around with a 12V but again did not get anything to lock/unlock
