I'm trying to diagnose a non-working power lock system in my 93 EX, and think I have determined the lock control unit is to blame.

While troubleshooting, I noticed this connector dangling just behind the fuse box:

It's the gray connector with grn/wht and grn/red wires. I looked all over the helms schematics and connector locations, but was unable to figure out where it goes. There doesn't appear to be anywhere on the fuse panel for it to go. Does it have anything to do with power locks, or us an unused connector?

 

I found the same thing last week while trying to find my non existent SRS reset jumper lol I'm also curious as to what the heck it is. Although my power locks work perfectly so im gonna say that has nothing to do with them.

 

That is for the OEM security system. Ground either one of those wires and you'll find it locks/unlocks the doors .... well, provided your lock control units works of course.
