Subject: Re: FTE 61-79 - EFI on a '73 302

First I'd like to thank all who have responded on EFI. My friends was
the first one I have worked on and was surprised how simple it was to
work on. I would like to go with this even if it's not the best
conditions, it's better than what I have.

From: luxjo thecore.com AKA OX
>What years? 86 through 88 T-birds used the non-HO 5.0. 86, 5.0 HO's

I was given bad info OX. On EFI for beginners they say All 5-liter
Mustangs built between 1986 and '95 (and all 5-liter Mercury Capris
built in 1986) are equipped with sequential electronic fuel injection, a
type of port fuel injection. At the heart of this system is the EEC-IV .
So does that mean I can get some of my parts from an '86 Capri?
After reading your post I began searching the Internet and found a
great site with all the info I can handle for now. I will share what I
find with the list as much as I can, if only to add graphics so all can
see what OX describes. So far I have only found info that concurs with
OX, but still worth a look.

>May want to get aftermarket harness to simplify install.

I found harnesses at http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.greenapple.com/~jcurrence/fuel.html and
there are some kits, I would like to know if these are what your
speaking of

- ------------------------------------------------------------------------
- ---------------------------------

ENGINE HARNESSES AND CONTROLS PACKAGE
M-12071-E302 5.0L/302 HO & 5.8L/351W FIRING ORDER 1-3-7-2-6-5-4-8
$126.90
You'll need this package to complete a 86-93 5.0L or 5.8L engine
> assembly with EFI. Kit includes all sensors and wiring harness mounted
on the engine(ACT,ECT, and EGR position sensors, EGR valve, oxygen
sensor harness and fuel injector harness). Note that 5.0L/302 HO and non
HO engines use a different firing order.

- ------------------------------------------------------------------------
- ---------------------------------

OK, this was a happy find. A good chunk of what I need isn't it?

- ------------------------------------------------------------------------
- ---------------------------------

MULTIPORT 5.0L EFI WIRING HARNESS COMPONETS
For 86-93 5.0L EFI ENGINE CONVERSIONS ON STREET RODS, KIT CARS, TRUCKS,
AND PASSENGER CARS
MAIN HARNESS M-12071-C302 $310.00
The foundation of Ford SVO's Multiport EFi Wiring Harness system, this
harness connects the mass air flow computer to the engine, sensors, and
relays. 26 page instruction book included with main harness. Contains
very detailed instructions, helpful hints and lots of illustrations for
easy hookup.

- ------------------------------------------------------------------------
- ---------------------------------

If this is what I need, it still isn't bad but it's only the harness

- ------------------------------------------------------------------------
- ---------------------------------
COMPUTER And MASS AIR METER KIT
MANUAL TRANS M-12071-F302 $285.00
Boost you fuel economy! This mass air flow computer system operates with
performance engine assemblies and stock high output engines. Kit
includes the EEC-IV computer, mass air meter, inlet and outlet hoses,
plus mass air meter mounting bracket.
- ------------------------------------------------------------------------
- ---------------------------------

It's for a manual trans but I was thinking that's what I'll need with my
C4. If it's for an auto it would be an A4OD right? Well that's all the
parts for now. I'll post others that I find unless people don't want to
see it. It seemed that others may be interested what this would cost and
what it would take to do it. If I run across parts for other engines I
will include them too.

To understand EFI I found this site called FUEL INJECTION FOR BEGINNERS
at
http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.iaw.com/~aubertin/88mgt/eec-iv/mmff/mmffuel1.html it was
linked from The Corral at http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.corral.net/ where there's a ton of
information on EFI and ignition related links.

That's what I've read

Right again. Here's what it says

the ignition module (TFI) on the side of the ....
