dreaded wiring harness issues...

i just finished installing 2 front frame rail roll cage tubes thru the firewall to stiffen up the chassis.

i had to use the ford holes/cutouts where:

drivers side the main body harness goes from dash to engine compartment

passenger side where the eec harness goes to the engine compartment


now, thats left me with 2 harness inside under the dash that go from the interior to the engine compartment thru whats left of the holes in both sides where the rubber grommets on the ford harness seal to the firewall.

my question is:

any suggestions how to clean up the wiring so that it seals the engine compartment from the interior of the car?

any suggestions how to clean up the wiring so its neat and tidy?

its a mess now with all the wiring under the dash. i have all the ford wiring, plus gauges, plus pms system, wideband, datalogger and air/fuel ratio wiring.

not sure how to best clean up the mess. make everything look neat and tidy and clean.

any suggestions appreciated, thanks

At this time I am not aware of anyone making a body harness. I cant believe
nobody from the aftermarket has it offered. It might be a OEM copyright thing
right now. There is a ton of good aftermarket stuff offered that is real nice.
Even though they may not be a harness you may have to make your own.
The aftermarket has great relay boards,real nice wiring ,small wiring
labels,wire-braid,etc.With all of this you could make it nicer.


I think if there was a OEM harness available, I would not buy it. I plan I using
wetherpak connectors on all points. My car does not have A\C and many
options so alot of that wiring would not be used. If you are doing something
more of a OEM restoration your SOL. Good luck in your vision.

Not muchnof a vision yet...

I installed a dash bar and had to move all the wiring under the dash..now I'm left with a birds nest...

I ordered some ford shop manuals so I am going to try and put everything back where it came from...

I know I need to run a new painless efi harness on passenger side through firewall I had to use the EEC harness hole for the roll cage to frame rail tubes

And I used the driver aide main harness hole for the drivers roll cage to frame tube.

Now I need to find new routes for those harnesses and figure out all the gauge wiring routes...

Seems like I have to take a look and see where I can run things

Wanted to hide as many wires as I can and clean up the wiring so it's more organized.

Any thoughts were to get good wire like 14 gauge? Need a variety of colors so I can run new wires for all the extras in my car like gauges and ignition system and misc stuff...

I can help you on the very best wiring I found, call Summit and pick up
their 14-gauge wire. Its the nicest type, all different colors and its spooled.

Planning on doing the same as you next summer. I know painless offers a universal kit with a
fuse block. I don't like how it would never fit in the OEM section on my dash. Planning on
retaining the OEM fuse block, adding all new wiring behind it. All shrink wrapped, and there are
some labels you can get specific for wiring.(exp-headlights,windows,ect).If you plan it out,
and study some of the pics some pros post on different sites your project can become
a work of art.

not even sure where to start. had such a mess in there.

i have a mess of wires...

factory ecm harness
factory body harness

gauges
stereo wiring.. think im gonna delete
pms system
wide band
trans wiring
wideband o2

i have managed to get a painless efi harness. i want to put that in, and remove the ford eec crap.

i got the shop manual and electrical book.

i have so many patches and relays and unused plugs on the main dash harness. i want to cut everything out i dont need, but im not sure where to start. not sure what ill need later. not to mention my painless harness is in storage somewhere.

think i need some supplies like wire, loom, deutsch or weatherpack connectors and a wiring diagram of what is already connected.

i was looking at the racepak digitl dash and get rid of all the autometer gauges to clean up the wiring somewhat. for the autometer gauges i just used the factory harness, and theres splices and unused plugs.seems like i could clean up some things with the racepak...anyone have experience/comments about racepak?

seems like theres a 1000 wires to figure out. whats good? whats bad? not to mention its freezing outside so all the wires are cold and not really cooperating...

there are a ton of options all depends on what all you want you can keep everything and then some just have to plan it out on this car here we kept all factory switches operational now that took some time with an ohm meter to see what pins do what but we lost all factory wiring and when its done well have everything we did before except now its alot more versatile

So where to start?

I guess by getting some supplies:

wire markers that are numbered 1-100 so i can find 100 wires and trace them end to end so i know what im working on

label tags so i can label each plug on the harness for quick reference

zip ties so i can cut the harness tape and still keep the shape

goop off to clean the sticky tape residue

ford electrical diagrams so i know what wire is what

digital volt ohm meter for testing

scissors, crimpers, strippers, soldering iron, heat gun, heat shrink, terminal connectors and non-sticky tape

The Powerprobe PP3LS01 Combo Lead Set



The absolute best electrical testing system i have seen...you can test elctrical wires and components, and even trace wires through a harness. If you have a job like this, your moneys well spent on this:
http://www.powerprobe.com/powerprobe/PP3LS01.html

I still have to get

lots of electrical wire automotive or marine grade
deutsch or weatherpak connectors, specific crimpers for these connector pins

and a few other goodies...

I managed to get the dash out, and hung the wiring harness where it will be going.
I spent some time thinking about what exactly i need to get done, and make a quick list.
I pretty much want to clean up the harness of anything I'm not going to use to make it as small as possible, less complicated to troubleshoot, and find any issues now while everything's apart.

I want to run the main body harness through the firewall into the fenders..thinking the cruise control harness hole in the drivers side of the firewall will work.

Thinking i can use the same area on the passenger side to run the new painless efi harness to the engine through.

I have to make my own wiring diagram of all the electronics i have installed over the past years building the beast.

in short:
About 12 gauges
Line locks
Wideband o2 sensor
PMS system
trans brake

MSD Digital 6 box

Its a start... keep tuned for the work and some pics

Take a look at isispower.com Little on the expensive side but will
make up for it with less labor and wiring in the long run.

That looks very familiar. My harness is even draped over my column just like yours. I'm debating going with the painless 12 circuit kit that has electric fan and electric w/p relays. No HVAC option so its going to the way side for now. I was going to try and clean up my 93 abs/airbag harness but my time spent doing that would cost way more than the painless harness and supplies would run pretty high. Best of luck.
