Electrical diagram for wiring up PFC
 

This includes ECU. Anyone have one or know where I can download one?

Much appreciation

wiring up what its a plug and play ECU.

4 wires need to be cut for the car to idle below 2k rpms, you should be able to find it with a quick google search.

Well the last owner of the car screwed something up. Now my commander won't actually command. Any input i put into it, nothing happens. It won't respond to any of my changes.

So i would like to rewire it from ground zero.

There is nothing to wire, it is a plug and play unit. As David mentioned there are 4 wires that need to be cut on the harness or pins removed on the PFC but they have nothing to do with the function of the commander. Are you getting a display on the commander?

It doesn't sound like your problem is with the ECU connection to the engine harness. It sounds like it's the connection between the Commander and ECU.

The connection between the Commander and the ECU is pretty sensitive, and even if it looks like the plug is all the way in, it may not be. Check that first. Mine did this once and the screen was completely blank. If that ends up being your problem... I resolved it by pushing the plug down all the way and then daubing some silcone around it and not moving it until the silcone set. It's now held firm and the silicone keeps any possibility of moisture or dirt out, but I can still pull it out if I need to.

IIRC, there have also been occasional issues reported on some units from the wire leads being too short as they enter the commander display. Simple movement of the cord over time can work one or more of the wires loose from the board inside the display head, requiring some solder work.

Chadwick - Yes, i am getting a reading on the commander.

Signal 2 - I will have to look into what you mentioned tomorrow. Hopefully it will be something as simple.
