I broke one of the connectors when removing the FICM. What can I do?
If all that broke is one or both of the clips that ensure that the plug doesn't work itself loose, many have had good luck using heavy duty zip ties around the module to keep the plugs fully seated. Others have had luck taking a maybe 10" section of radiator hose, sliting it length wise and installing it under the module as a way to press the plugs continually back in. If your damage is more severe or you just want the 'right' solution, there are two options. The first is a replacement harness, but be prepared for some sticker shock. The injector harness (the plugs nearest the front bumper) retails in the $200 range and the ECM harness (the plug closest to the firewall) is closer to $800. Alternatively, you can try replacing the plug ends. A great write up can be found here
