How do I disconnect this connector?

I'm sure you'll recognize this picture - it's part of the driver's under-dash fuse/relay panel:

One question: How do I unplug the lower of the two green connectors? There's so little room in there that I can barely touch it, no less pull it out. I tried using a flat-blade screwdriver to work it out but it must have a lock, presumably on the backside. But there's no room to get my fingers in there to feel around. What's the trick to unlocking and removing the connector in such a cramped space?

I thought about unbolting the entire relay panel but it appears the cable harnesses don't have a lot of slack and would still keep the panel in place so I'm not sure if it would help me achieve my goal.

I have the service manual (calls it the "P" connector) but it doesn't explain how to unlock or disconnect it. Anyone know how? Suggestion?

PS: This is for an '08.

Yeah. Its got me curious as well. Why are we unplugging that connector?

And why may I ask, the reason for this procedure?

:eek:
That connector carries the power-lock & unlock wires and I had an after-market device wired to it that is behaving erratically so I'm suspecting a faulty connection. In fact, you can see just to the right of the connectors some electrical tape covering the connections that I want to examine. But it's so cramped, I cannot even get my fingers in there to unwrap the electrical tape! Since I probably have to resolder it anyway, I was thinking that unplugging the connector would make it easier to unwrap, solder, and rewrap the connection.

It occurred to me to stop by the Honda dealer and buy the connector just so I could find and study the lock. Alas, they only sell this connector as part of a harness and they don't stock them. (And it's $72!!)

Am I going about this the wrong way?

Maybe you can post more info about what the device is doing that is "erratic". I assume it is a remote starter or aftermarket alarm system?

I'm no auto expert but I do work in I.T and I always try to rule out the simpler things that may be wrong before I move on to the more drastic/expensive areas. What has led you to believe this connection is the problem?

If it will help inspire an answer, I'm happy to provide more detail.

It's an exterior keypad. Sometimes it works (unlocks), sometimes it doesn't. But it always disarms the alarm, so I know the keypad itself is working reliably - because the same keypad output feeds both circuits (both the disarm and unlock circuits, that is).

As a doublecheck, I've swapped the keypad with an identical unit with the same erratic results.

This is why I'm focusing my attention on the connection to the unlock circuit under the dash.

In a feeble attempt to rescue this thread (and my reputation, such as it is) from your ridicule, here is an actual technical followup...

In the end, I gave up trying to disconnect that connector. Instead, I crept in far enough to remove the electrical tape and resolder it in place. However, it didn't fix things so ...

I'm now convinced that it's a limitation of the Ody computer. I cannot trigger the disarm and unlock simultaneously. The computer simply doesn't listen to both at the same time. If I knew how to speak to the B-CAN bus, I could do it that way but that's undocumented (as far as I can tell).

I'm thinking of three workarounds (I've tested the first two):

1) Use the keypad's auxiliary controls. These are meant to trigger other things like opening the hatch or sliding doors with another button once the initial code has been entered. I actually tested this and it works. The time it takes me to move my finger to another button (tenth of a second?) is sufficient for the computer to start listening again and unlock the doors.

2) Put the unlock circuit on a relay, thinking the natural latency in the relay might be enough time. But it wasn't. (Is there such a thing as a relay with a tunable delay?)

3) Connect directly to the unlock solenoid in the driver's door. I'm not sure it's wise to bypass the computer so I haven't tested that and am not sure I really want to as it only opens the one door. (My 1st workaround talks to the computer so it follows the computer's current setting which is to unlock all the doors.)
