Well if thats all you know you will have to get a Auto Elec. But half the people on this forum would have a go themselves. To start with, take all the black tape off your cut loom so you can see whats what. Then read all the instructions that come with your computer, get wiring diagrams for both your new computer and 20 valve and go from there.

doesnt sound too hard, ill have a go at it but yeah im not the best with engine wiring and i dont wanna blow up the ecu or damage anything lol
but yeah ill have a go at it and see how i go

Wiring an aftermarket ECU is easy, but time consuming to do properly.

Read the manual first and get a wiring diagram for you 20V. Also a generic loom to suit the ECU is a good basis too. I'd suggest cutting all the plugs off the 20V loom (with about 6" of wire left) and plugging them onto the engine. Then work out which wire from the ECU needs to meet each of the wires now sticking out of the 20V. Run it nicely, solder and heatshrink. When finished, loom and cable tie the bundles of wires.

Then enjoy driving an electrically reliable car.

so u reckon ditch pretty much the whole loom and leave a bit of wire off each plug to connect wires from ecu onto then just create a new loom yeah?

souns like a smart idea to me, use a long peice of heatshink to cover the join all the way to the plug covering the old wire. It makes it look like factory fitment
