I'm installing a Hornet 742T in a 97 civic LX. I'm trying to get the drivers side door to unlock with the first click of the remote and all doors to unlock with the second click.
Some of the wiring info that I have seen says that blue / YELLOW will unlock only the drivers side door. When I measure with a dmm, I get voltage on the lock/unlock wires (GREEN/ orange and GREEN / WHITE), but nothing on the blue / YELLOW.
Looking at wiring diagrams and troubleshooting directions (in the Honda service manual), the blue / YELLOW wire seems to connect to the power door lock control unit differently. The tests for GREEN/ orange and GREEN / WHITE look for voltage and the tests for blue / YELLOW only check for continuity to the lock control unit.
Does anyone know what signal is required on the blue / YELLOW wire to cause the drivers door to unlock?
Thanks

You will need to use H-3  ...  BLUE wire for Unlock All Doors from your Hornet

I connected h3/1 (blue) to GREEN/ orange and can get all doors to unlock.
I connected h2/c (GREEN/ black) to GREEN / WHITE and can get all doors to unlock
I connected h2/f (blue/black) to blue / YELLOW and the drivers door does not unlock.
I believe that h2/f goes negative on the first push of the unlock and h2/c goes negative on the second push of the unlock.
I measured GREEN / WHITE (and GREEN/ orange) to ground and get constant voltage. I measured blue / YELLOW to ground and don't get anything. But based on what I saw of the circuits in the user's manual I don't know if I should see voltage on blue / YELLOW or not.
Thanks

For anyone else with the same problem:

The blue / YELLOW does work to unlock the drivers door only. There's a connector on the left side of the fuse box. In my civic, the blue / YELLOW wire did not have continuity from this connector to the security plug by the radio. So I tapped in at this connector and got the system to work the way I wanted it to.

But be careful - there are two blue / YELLOW wires at this connector. One of them is the door lock, the other is for the radio. As I've seen elsewhere in this forum, be sure to check with a meter before you connect.
