Just a couple of questions.
This is a an LPG conversion.

1. I need to connect to the negative side of the coil.
Low tension.

The coil where the spark plug leads leave has a connector that
has one small green wire and 3 yellow wires. (Strange why not 4
unless in two cylinders take the feed from one wire and get fired twice
a
revolution I assume?). Can I just connect the wire to any of these
wires?

2. The injector
I need to switch the injector off with a relay. I notice in the
throttle
body there is a connector (2 wires) going to a device directly in front
of
where the throttle opens will this be the injector? I have looked at
the wiring and I was expecting larger wires going to it to switch it.
I assume I can start the engine on petrol and disconnect this and if
the
engine stops I've got the injector.

Just one question.

Why?

Unless istalled profesionally the LPG conversion invalidates your 
insurance cover - lke from today if you have already started fiddling 
with it!

If you don't mind me saying, it seems a rather old and small engined car 
to be bothering with a LPG conversion. Most people who convert to LPG do 
so with newer, larger engined vehicles, where they anticipate long 
term/high mileage ownership and stand to gain a big saving on fuel 
expense. Not that it's any of my business. Perhaps you're doing it 
because you can get all the equipment for nothing and you intend to 
install it yourself?

Not so sure about that.

It's a modification which would need to be declared, and the insurance
company would want to see a certificate showing that it has been
properly installed.

If you either don't declare it or fail to get it certified, then
insurance would be cancelled.

There should be 2 yellow wires on the coil, connected to pins 1 & 2, these
are connected to pins 1 & 19 respectively on the ECU. Either one of these
can be used to give your coil signal. Note that these only give a pulse once
each every revolution, rather than twice per revolution as on a conventional
coil. This may give you problems with the LPG setup, e.g. if the engine has
to be revved to a certain speed to get it to switch to gas after the initial
start, then the speed will need to be doubled. If this is a problem, you
will need to connect to both wires, to get 2 signals per revolution, using a
pair of diodes to prevent the signal crossing to the other yellow
wire.(connect the cathodes(the end with the band) of the diodes to each
yellow wire, connect the anodes together and to your coil signal wire on the
LPG kit)

The other 2 connections to the coil are pin 3, ign switched live(yellow and
red), and pin 4, suppressor.(green and black)

The injection body should have a 6 pin connector, located just under the
throttle cable.
The pins are..........

1) Green, Ignore
2) Yellow, Injector, ign live feed.
3) Yellow, Injector, ECU switched earth. Connected to pin 18 on the ECU.
4) Green, Ignore
5) Brown, Ignore
7) Green, Ignore.

Either pin 2 or 3 can be cut to switch off the injector, this may however
give an Engine Management Fault light on the dashboard, if the ECU detects
that there is no current flowing through the injector. The solution to this
is to measure the resistance of the injector, and switch a suitable resistor
across the injector wiring using the normally open contact on the relay.

I did my own conversion, was not certified, was no problem whatsoever with
the insurance company.

Fills me with confidence that there's home-brew gas conversions out
there.

It's pretty dangerous stuff, I'd definitely want to know that all
conversions were done properly, not hacked together by an amateur in
their shed.

Don't know if it me. But none of the colour codes match my car.
Seems to be the thing with citroen.

Because I already have the kit. Just moving it from car to car.
Pays back virtually straight away. Taken the kit out of my Citroen AX F
reg.
Before that it was in a Proton 1300.

WHY?, ffs, WHY?

I can understand it in some gas-guzzling V6 / V8, but in a crappy
pensioner's shopping trolley with an engine barely bigger than a bike
engine?

So you think that all DIY on cars should be banned then?

There are far more dangerous things than tanks of LPG. (tanks of petrol for
instance)

I'd certainly want to see evidence the tank was properly mounted in the
boot. I've seen some real bodge jobs done even by professionals.

Exactly. So why should a DIY be any worse than a "professional" job?

After all, a dodgy pro knows he's never going to see the damn thing again, 
whereas the DIYer knows he's going to be driving it 20,000 miles per year 
himself. Vested interests, innit?

Hmmmm, I suppose I look at it from this point of view.....

Will the kind of person fitting LPG to a 1.1AX really be the kind of
person who'll do the job properly, including spending the money on bits
specific to that application? If you're so tight that you'll stick LPG
in something as economical as a 1.1AX, then you're the kind of person
who'll bodge things rather than buy the correct bits, IYSWIM.

DIY cars have to go through SVA testing.

Exactly, some professionals make bodges, some amateurs make bodges.
The difference is, you tend to take a little more care if it is your own
vehicle you are working on.

That's only if your building a complete new car, not doing everyday DIY work
on an existing car.

Design and build a car yourself or build a kit car and it has to go for 
a SVA test.

Actually from what I've seen, people tend to be more likely to "take a

Some kit cars.
Some self-built cars.

That's rather a long way from "all DIY on cars", though - even YOU have to 
admit that.

With the exception of most that contribute to this n/g. :-)
How many DIYers really know what they are doing when working on their cars?

No worries.

Even so, SVA doesn't really test for build quality - it's far more of a 
check of compliance with C&U.

Because I do a lot of miles a year and this conversion even in my
little car which I trip to work and back in everyday. Will still save
me £750 pounds a year. Which is the price of a nice holiday for me. :-)
