My program appears to not be opening.

This photo here - just about where you cut it there is two connectors that you need, they are the ones to connect. So the loom you have cut, most of the wires go between the engine and the ECU, it is a simpl case of joining them together, I had to solder all mine together.

It is good if you have the whole loom as I did, you can then use the factory plugs. So 1st thing is to join the loom to the motor.
Then you will identify the plugs I talk about a white one and a brown one.
There are two relays you need are one to work the fuel pump and one 'main relay'. They are already in the loom and you can see them in the photo. They are the silver relays, the two yellow and one green one are to do with the air conditioning.
The fuel pump relay needs power from the exterior fuse box. Thats one wire.
That main relay needs power from the exterior fuse box. Thats the 2nd wire.
The Fuel pump relay has an 'out (87 pin) that goes to the fuel pump
The Starter wire needs run
Then you need power for the ECU, this comes from the key when it is in the "on" position, the one that controls the coil etc, so when you turn the key off, it turns the motor off! This one is generally straight from the key and is also fused.
Those are the basic wires, I'll try take some photo's tomorrow so you get the idea.
I do know some models earth differently. I have one here with multiple earths and another loom that is one earth with a big junction box. I did alot of reading to get mine going.
