Some background:
I'm fitting a late XE into my Avenger, and am using the stock EFI. But, I didn't remove it from the donor car and have had it knocking about the garage for some time.

Using a Carlton sump and gearbox, fabricated mounts, plus a generic RWD exhaust manifold, it's in the car.

The car has had an Astra radiator for some time, so I've made a new stainless water rail, and top hose, plus will be using a Golf expansion bottle.

I've fitted a Discovery submerged fuel pump, and run new fuel supply/return lines with a 2.8i Capri fuel filter.

I'm now at the wiring stage, and have connected: the rigidly mounted injector plugs, the MAF and TPS sensors, the subloom for the ICV and knock sensor(probably), the vacuum sensor at the rear of the inlet manifold, the DIS pack, and the cam sensor. There are 3 earths that connect to the inlet manifold. On the other side of the engine I have both the water temp sensors, the crank sensor, the lambda sensor, the battery connection with the ignition timing plug and the big grommet for the bulkhead leading to the ECU and relay. There is nothing else on the engine.

So, can anyone tell me what the 7way multiplug(that has 5 wires in it) on about 10cm of wire that comes out of the loom between the DIS plug and the cam sensor plug at the back of the cylinder head is for? And if so, can I ignore it?

I'm no stranger to EFI swaps, having done several Fords, but this is my first Motronic one.

Also, the exhaust manifold is a 4 into 2 into 1. Putting aside that it's down to Ashley's usual poor standards, can I weld the boss for the lambda sensor into one of the '2' parts of the manifold, or must it go into the final collector?

Thanks in advance,
Nick

Hmm, not sure what you mean. Sometimes a pic is worth 1000 words

Speaking of pics, show it off, including ongoing development

Having spent the last month on various jobs on this, the car is now getting very close to starting.

I have it cranking over but with no spark or fuel.

I finally figured out today what the 7 pin plug does; it's the ignition amplifier which I should get in the week. That explains the lack of spark!
The fuel appears to be a faulty pump relay, as swapping it for the spare one on the remains of the Carlton loom in the garage has that working correctly.
So, by the middle of the week I should have it running, which will mean pulling the engine back out to sort the clutch, and then it will be drivable.

Which should be fun!

Lambda sensor in one branch will be OK. Ideally, you want it to see the mixture from all cylinders, but mixture between them should be pretty even so no problem there.
