Its an easy job! Disconnect the battery first! That's very importand! Then disconnect the wiring pack from the ECU. Some models are equipt with snap-systems, other with a screw-system to remove the wiring connector from the ECU. If done, there are three or four screws that hold the ECU in place with the body. Remove the screws and you hold the ECU in your hands. To buy a new or rebuilt ECU, reffer to the numbers shown on the label at your Wranglers ECU in combination with the V.I.N. To connect the new ECU with the wiring pack, be careful with the connector! You need to put him in the right position to connect with the ECU. Do it slow and make sure the connector fits to all points. Otherwise you'll bake some contacts inside the connector.
