DO NOT PULL the plug out unless you are sure you've gotten the spring unlocked or else you'll mess up another connector.

Another way to get at the connectors is to actually unbolt the MCM and BCM, turn them over to access the connectors and the plastic spring lock on the connector.

Good luck and I hope that the broken one plugs back in correctly...

Thanks for the information and the kind thoughts. I'll post the results.

Hmm. If that's the case, he could turn it back on, reset the IMA and idle it for a bit to bring the SOC up before turning it back off.

During an IMA relearn, the car will apply a charge to the deadest of batteries before giving up, and the V pops up in a matter of seconds under that kind of charge. The engineers designed it to handle the car that was left stored at the dealer for a couple years.

Or he could just unplug the BCM and be done with it.

As others have said, the release button is on the bottom.

Fortunately for you, you broke the one that is physically part of the battery AND you plan on replacing or bypassing that battery, so it will be swapped out anyway. You can simply leave the orange cable unplugged if you wish. Had you broken the back one, you'd have to replace a chunk of wiring harness.

Unplug the grey-wired connector on the other side of the BCM that is closest to the driver's side and you'll be good to go as a gas car.

The "bigger hammer" rule doesn't apply to the Insight. If it doesn't move, you missed something - don't force it.

Front connectors:

I'd really appreciate instructions for pulling the connectors and suggestions for dealing with the broken connector. I'm hoping the plug holds together and when I put it back on maybe I can glue on the broken piece for protection.

Thanks Again!

Good advice. On all the battery connections, there is also the clik rule. If It doesn't click when connected, it ain't connected.

Thanks again! I couldn't remove them until I turned the BCM over.

It came out intact so I think when I get a replacement battery the connector will work ok:

The glue might help:

While it was apart I built a lifter modeled after Mike's (same height). To use it I'll just screw or bolt a 5 foot or 6 foot 2"x4" onto the top:


I don't have an Impact Driver so I have not replaced the six Torx T30's. I'd prefer to use bolts with 10mm heads. Anyone want to either sell me some or know where I can get a good deal on six bolts?

There are three bolts at the rear and three push-clips that look like phillips-head screws. Use a sharp knife to pry up the center of the clip and remove it, Then the ring can be removed.

It looks like they are screws, in the center, that could be unscrewed instead of pried.
