It just like any connector for any application. Get a removal tool and get new connectors.

Here is the connector.

You can use this removal tool.

Here is a decent video showing how to remove the pins from different type of connectors, not exactly the same, but they usually come out the same way.

thanks All,! i actually got them removed with a very small flat head screwdriver and breaking the old connector carefully to disengage the retaining pins on the actual connector. otherwise it wont budge by only using the very tiny screwdriver. hope this helps someonr else.

final question does anyone have the wiring diagram of the four wires with color description for each connector to coil. this will help anyone who forgets which wire goes on which pin in the connector.

Do you remember what exactly you did? i'm having the same problem right now.

it was a bit hard. I had to use sharp cable cutters to destroy the connector as much as possible. I then inserted a very tiny flat head (type used on watches) on each pin and removed each one carefully. Just remember where each one goes. Took me about 30 mins to do this.
