Does anybody have the wiring diagram for the ECU. Just sent mine off to GDE for the tune/flash and they are having a problem communicating with my ECU. Keith was surprised my Jeep is even running with this ECU. Looks like I have a grounding issue to track down. |

This is where reading the NOOB guide at the top of this section can assume great import: service manual information is entailed, therein - read thru and weep............................................ |

There is no actual wiring diagram for the ECU internals...shown as a black box in all the circuit diagrams. You can download the KJ Service Manual of your year model here but it will only give you the names of the connector inputs/outputs which I am sure Keith already knows. Maybe you are lucky and someone who actually repairs these items chimes in with a circuit diagram.  http://www.colorado4wheel.com/manuals/Jeep/KJ |

Fairly certain the dude wants to troubleshoot his KJ wiring to\from the ECM, but I'm sure he can speak for his own self................. |
