Irmscher injection loom

[Edd]

Started sorting the loom out today

I know there's not many people using this set up but I'm stuck lol

I do have a set of instructions to look at but there not very good tbh, no colours for start on the wiring diagram

What I've got on the loom to wire it in,

Fat red - positive
Fat brown - earth
Green - coil
Small black - ?
Black with red stripe - ?
White with green stripes - ?

I'm thinking that the black with red stripe is ignition live

But no idea on the other two

Any help would be awesome as I'm very close to being able to start it up for the first time :)

I think I sent you all my info iirc, yes I know it is black and whitelol

[Edd]

On those instructions if you can call them that lol

One says cranking motor which I presume is ignition live

On says fuse box terminal 15

No mention of another tho and no colours lol

Think one could be diagnostic ?

[Royston]

On those instructions if you can call them that lol


They were direct from Irmscher I'll have you knowlol

I'll dig them out for a look and try and refresh my memory;)

[Royston]

Cranking motor could well be starter circuit, i.e. F I knows to initiate start up, (fuel pump live, if Rover flapper F I is anything to go by)

terminal 15 is probably the switched live feed.

There are also 2 harnesses, I have an old and new one, NTC is a crank timing sensor, not on UK systems (cat fitted?)

Alternator connection to show out put when engine running, I suspect

Duick may know more;)


Last time I send you some instructions:roll: .............lol

[Novasport]

On the wires that hav no multiplug they go to...
Alternator live - Red
Earth - Black(Odd as black is ignition live on Opel/Vauxhall wiring)
Ignition coil terminal 1
Fuse box terminal 15
Cranking motor terminal 15(Starter?)
Fuel pump(Wire that comes directly from ECU plug)

[Novasport]

Best I can do...

[Novasport]

Unfortunately it looks like someone has squatted a daddy long legs on the page lol

[Edd]

^^ that's the diagram I have fooking useless tbh lol

The ground is deffo brown it has a large ring lol on the end and was earth through the alternator earth when I took it all apart

Black with red stripe is looking like the starter I think as that's what's on the starter

I'm thinking the small black is ignition live ?

Then there the other one lol

[Jack]

The wiring diagrams in Haynes has the 1300 injection system on it if thats any help

[Edd]

Really !!!!??

Off to garage to dig out the Haynes lol .............

[Jack]

Yarp, looking in mine it has Throttle Body Injection C13LZ on the 86, 87 and 88-89 diagrams

[Novasport]

That is single point injection for the European market

[Edd]

I'm not sure if a C13NZ is a Irmscher injection kit tho as it has a Lambda sensor and Irmy injection doesn't

[Edd]

All I need is a diagram like the Haynes one lol

I sent duick a PM may he knows

[Edd]

After some googling mark/novacabrio had a thread on mig, small black wire goes to the black/yellow

This is correct cause my loom still has a bit of black/yellow on the end of the black wire

It says it connects to the manual choke wire, I presume that is the spare wire in the small bit of the loom where the oil pressure sender wires are ?

[Jack]

That is single point injection for the European market
D'oh of course, Z being SPi. I fail lol

[novacabrio]

One of the wires earths with the wiper motor, I can try to find my loom and see where it all goes.

[Edd]

That would be ideal as I havnt got a clue

[C612DNM]

Terminal 15 is ignition live - it's another of those wiring standards, like black for switched live (ignition), and brown for ground.

[C612DNM]

Black with red stripe is "starter" - as in for cranking enrichment.
That'll be cranking motor terminal 50.

What does that leave you with? white/green - a process of elimination should get you there - what haven't you got connected?

i would hazard a guess that the one connected to the manual choke wire is so the choke light gets used as an eml

[duick]

There's no wire connected to the choke wire

[Edd]

Think I'm sorted

Fat red - positive
Fat brown - ground
Green - coil
Black red stripe - ignition live terminal 50
White green trace - ignition live as above cause the shrinked together
Black - fuse terminal 15

Someone please correct me if I'm wrong tho

Also does terminal 15 refer to the fuse number in the box?

Or The numbers after the diagrams in the Haynes ?

[duick]

15 in the fuse boy is the same as 15 in the wiring diagram. It's ignition live

[Royston]

Is it running yet then?

[Edd]

^^^^ F lol that made me smile lol

NO ! Nearly few more days I reckon, waiting on a couple of parts

Hope I've sorted where all these wire go

[Edd]

Another question lol

On this primitive injection system is it going to matter which injectors the 4 plugs go too ?

As there's not mention of this in the instructions

[Novasport]

BTW Edd, how are you fitting the loom? On the fitting instructions it shows the cutting of the bulkhead to fit the loom through!
Seems a shame to cut the bulkhead. If I were going to fit it I would strip back the standard loom and feed it into that, extending wiring where required for a more OE look.

[Edd]

There was no way I was boring a 47mm hole through the bulkhead lol criminal stuff that lol

Errm I've stripped a loom back and didn't number which pugs went on which injectors

Does it matter ? I'm thinking that it does :(

[mowgli]

yes it does.

[novacabrio]

I don't think it does. If you traced it back I'd be there is only 2 wires coming to the injectors then splitting off

[burgo]

i would very much imagine such an old system to be batch fire, sequential injection is still a relatively new thing

[Royston]

Rover V8 injection fires in 2 batches, so split in to 2 circuits, it is also a flapper injection system.

Surely if you bunch the wires back up, you should be able to work it ou?

[mowgli]

surely the wire length will help, like ht leads...

[Edd]

Indeed

I'm sorted finally now

I was looking at it after a few cans so no wonder it didn't make sense lol

[mowgli]

you needed more cans...
