I'll check it out tonight, havent' gotten home before 10pm for the last 3 days...
FYI, ICO told me to do the following (which is what Lloyd is saying):
1. You don't have your sensor wrapped around the brake hose to the master cylinder. If you run the sensor wire along side of the brake hose and tape it to the brake hose, you will break the sensor.
2. You may not have the wires coming from the bottom of the CheckMate supported. If you allow the wires to hang down and flop around, the will break at the grommet.
To check and see which is the problem, get a paper clip. Touch the each end of the paper clip to one of the pins in the connector. The pins form a triangle. The top pin is a NC, (no connect). You'll use the the pins on each side of this pin. Each time you touch these pins it will register .01 of a mile for every 7 and them 8 times you touch the pins. If your CheckMate registers distance, then the problem will be in your sensor.
