Thanks for all of the advice from everyone. All of the mechanical work is complete. I'm just about to intorduce the new half of the loom into the car.

I will be positioning the ECU within the glove box and running the loom out around the engine bay. Before I begin to position the cables I was wondering if anyone could help me out with confirming the connections behind the dash?

I have 3 connections that come from a series of Relays (which i'm assuming will be the new Fuel Pump Relay set up?). The three cables colours are as follows;

1. Red
2. Blue
3. Black

There is also a smaller Black cable that runs into a connection block?

I will post a picture up when I get home tonight as it wont let me from work.

But thinking about it I would assume the following;

1. Red - Fuel Pump?
2. Blue - Ignition?
3 Black - ? Thought about negative. However there is a negative terminal further on down the loom which will be under the bonnet and go to the battery.

Small Black Cable - Rev Counter?

Cheers

Darren
