Ride: 86 xf fairmont 4.1

Location: waihi beach
New Zealand

I have a 86 xf fairmont which I changed from a carb to a 86 xf ghia efi system,I placed in the wiring loom and everything that goes with it.
I've ended up with a the plug that ends over by the steering wheel.
It has a number of wirers PINK/BLACK for the fuel pump,RED/BLUE RED/GREEN go to the ignition switch, the rest I have no idea where to
solder them too the color codes are PINK/BLUE,BLUE,ORANGE/BLACK,BROWN/WHITE.
I have two diagrams one in my manual and both give different color codes.So any help on this would be appreciated.
The next problem is I never took down where all the vacuum hoses
go so help on that would be greatful too.
Im going to have to get another manual this Haynes one does'nt cover
what I'm after.
Thanks guys.

Thats right,having the carb seemed to go through gas,just got tired
of having to watch my foot on the hammer,plus the car run real
sluggish and I was told efi would perk it up.
Good for towing but not what I'm after.
And I had a Ghia sitting here doing nothing but rusting away so thought why not,everything is here so I'll give it a go.
Going good untill my little problem,but thats my own fault I should've
been taking notes down as I went,guess you live and learn.

Here's another problem that I think most others have had with the xf's
those bloody DOOR HANDLES I have broken two of them in the same day,
just as well I've got spares,I don't know what they were thinking of at the time they invented them but I'm sure they could've come up with something better.
I don't know if there's away to get around them either,like if they've been
made in stronger metal since,or are we stuck with it.
I was warned bye a mate to watch the handles as he owned one a few years ago and had the braking problem.

Your going to break the door handles you put on as well - they made from cheap crap.

Change your door assemblys - you can get them new from ford or even ebay sometimes

I agree with interceptor on that one - XF + EFI = Trouble

Id rather use more fuel than have to worry when something else happens to the efi + electrics that run it

Oh and if you want power - go a model down and 351 it :P

easy way to fix your door handles is get the old ones and all the bits, drill a very small pilot hole where it breaks, put it all back together and put on a small washer and small self tapper screw, dont overtighten screw. so you still have free movement but no side to side movement on the arm. you will find these will last for ages as is alot stronger... old cabby trick that one...........

after 19-20 years, the difference wouldnt be that noticeable, and the EFI is a lot less modification-friendly

:lol: only when they're running 100% perfect without ANY issues at all, and thats pretty much a dream with XF's these days

make sure your door hasnt sagged, this puts extra load on the door lock which in turn causes the door handles to break
check the latch on the B pillar is level with the door lock, if not, adjust it
make sure the lock mechanisim is well lubricated
check the 3 screws holding the lock mechanisim onto the door, if these are loose, you'll have problems

It was pretty easy to change over to efi since I had everything on hand,
and I'm learning and understanding about the whole workings of a efi system as I go,(still lots more to learn)
The hardest part for me is the time factor,in my type of job I get a week
end off a month,so when my weekend comes up I try to do as much on
my car as I can that is if I haven't be torn away from it for some reason.
So since I've got this far on it I think I'll keep going with the efi system,
only a couple problems to work out and I'm there.
Hopefully once Im back on the road the efi will behave it's self,and I have no probs(wishfull thinking)
Any how I'd proberly be patting myself on the back with having gone efi
with the gas wise here.
I'll try that door handle trick when I get the chance to.
Thanks guys for your thoughts and help, keep it coming I need all I can get.
P.S What would be the best indepth manual I could get for the wiring & vacuum.

Did you swap ALL the looms from the ghia as you will need the dash looms and interior looms as well.
The plug you describe sounds like the one to connect to the efi loom. How many pins in the plug :?:

i prefer the ghia and 'laine cluster personally - and tho some people have problems with them not working all the time, i have been lucky thus far...

There is seven pins and the only wiring I replaced was the ecu loom,
I've had the car fire up and run for a few seconds but either I've got
the wirers to the ignition wrong or I'm not connecting an important one
up,the only ones I have been trying are the RED/BLUE,RED/GREEN,
which I'm sure can go straught to ignition,the PINK/BLACK I have running
the fuel pump.
I thought living the dash loom in wouldn't matter and I'd just need to splice
these wirers into it.
I put in the ghia cluster in and it lights up and all just to be nosey but gone back to mine.

Get yourself a max ellery manual. They have all the wiring diagrams and vacuum line schematics as well. The dash wiring does matter. If you look at the end of the dash loom you have and the engine loom for the efi there is one extra wire there. If you change this loom the ghia dash will work as well. But remember to change the sender units as well or the gauges will not be accurate. Did you have to change the fuel tank and fuel lines? I looked into this conversion and found that the tank on my 86 fairmont was not compatible due to the electric fuel pump being in the tank.

the pump is a drop-in type that is integral with the fuel level sender

not 100% sure if it fits the smaller tank though
