Does anyone have any illustrations/diagrams on how to wire the 1.6 16v sport engine into a 1.2 16v multi point injection?

we have installed the engine which came with a loom and an ecu, but i am unsure what to do with the old loom and cant find the old ecu. at the moment the engine will turn over but no fuel is being received. on the old engine there was two plugs with metal clips on which went to the back of the carb which i think ran the injectors and the fuel pump. i understand you did the same conversion yourself can you help?

The engine loom connects to the 1.6 ecu in the drivers footwell and the interior loom connects to the 1.6 ecu aswell.
That should be all that is required.
Have you got the keychip and transponder from the 1.6?

Get a pic up of what you mean, it makes it easier to understand.
And don't use text talk please!

carnt really get a picture of it to be honest: at the moment i have two ecu's in the car one for the new engine and one for the old one. on the new engine there is a loom it has a red plug and a white plug which fit into the new ecu that came with it. however if i just plug that in then the car will not no that the engine is there as only a few plugs off the old loom fit the new engine. so does one plug ie red run the engine and the other plug ie white run the electrics in the car? so do i need to plug ie the white one in the car (the old loom) into the white slot on the new ecu do you understand it that way?

The new engine loom should fit to the new ecu, and the old interior loom should also plug in.
There is nothing else to cut/connect. It's plug & play.

Is it just a straight swap then? unconnect the old one take it out put the new one in it and then connect it back up?

In practice it's easy aswell. Providing the looms are complete.

By the sounds of it, you are trying to fit the old engine loom onto your new engine?

to be fair mate I'm really good mechanically i changed loads of engines but i only do the mechanical work. my granddad used to do the wiring but he passed away recently so now I'm left to do that as well but i haven't learnt yet. can you explain what has to be done from scratch with the wiring just forget everything that has been said and start again lol? THANKS

You need to completely bin the old engine loom, the one which connects to the ecu, and travels through the gromet into the engine bay.
And then replace it with the engine loom from the new engine. That way it is completely plug and play.

It should be yeah. Just trace the old engine loom back into the cabin. It should go through the bulkhead somewhere. That will give you an idea of where the ECU should be.

it wernt in the car mate was in on the engine by where the carb is! we truyed to wire it up today but had no luck there is two plugs with no where to put them?? i have pictures on my phone and will post them later. the fuel is now running but there is no power running the ecu so we have no spark from the power pack. the old engine is a 1.2 16v out of a 1999 corsa so the ecu was on the engine not in the right hand kick panel! do you have any illustrations on how the wiring is done because there is no way the the engine is just pug and play.
