Sputter, cough, backfire loss of power, mistery solved!

My bike started acting up last thursday and I thought it was bad gas (Coughing only). Friday the same thing so I burned up the remaining fuel and filled up again. (I checked the board for similar problems and everything indicated it was the battery connections. I took the seat off and the battery was connections were tight, I check the air filter and the plugs, no problem). Saturday I didn't ride but Sunday I went for a 120 mile ride and no problem so I figured it was the gas.
Today I am on my way to work and the bike started doing the same but worst. Backfired, coughed and lack of power. 7 miles out and I had to turn back home. I barely made it.
So I checked the board for similar problems and everything indicated it was the battery connections loose. (Or maybe a foul plug). So I came home took the seat off and the battery connections were tight. I figure maybe a grounding issue because a week ago I installed the hondaline lightbar. Nope I can't find anything. Suddenly while I was putting the battery cover back on I got a glance of the ICM (ignition control module) and saw that the black wire was broken. I mean you could barely see that something was going on there!!!. I have no clue how this got broken but it did. Checking my service manual this wire is hooked to the Engine Stop switch and fuel cut-off relay. No wonder!
In order to fix it I disconnected the 22P connector and with a very small screw driver I had to push the square connector from inside the case. This is very delicate and I ended up bending it a bit. This actually took me awhile since I didn't know how it was hooked inside and I was trying to push in a way not to damage anything. This connector is very strong but it can bend easily. The wire was too short so I ended up extending it with another piece of same gauge wire. I put it back together in the box making sure it was in the right direction. Started the bike and VOILA!!!! (Stupid wire!)
I just wanted to document this in case another member has the same issue.

Thanks, good stuff! IMO some of Honda's elec connector's (like the 2 speedo nacelle) could be a bit beefier as well.

King Dude. I have the exact same thing going on. Based on your finding here I just came in from checking my ECM and all I did was touch the green wire and it fell off the connector. And it won't run without the green wire either. The black wire next to it is nicked through the insulation and no doubt will fail early. Honda dealer will get it courtesy of extended warranty. Thanks man it was driving me crazy.

This is an update. I delivered my 1300 to the dealer for the above described problem 11 days ago. All I had to do was show them my discovery and let the words 'extended warranty' roll off my tongue. They ordered and installed a new main harness.
I just drove that 1300 home this afternoon from Roseville Cycle Center in Sacramento Ca. The service writer let me know that the next two wires in line on the old connector were beginning to fail and would have eventually broken. And he achknowledged that this is a known defect to Honda.
Thank you kingato for showing me where to look. Everyone. If you are one of the riders who has an unexplained miss-fire really consider looking at the plug. It's on the top of the battery and feeds an electronic engine control unit.
