Okay last resort, Heres a shot of some wires coming out of the driver side loom in my 40. its a late 1970 or 1971 wiring set up. so there is another set of wires on the passenger side as well.

Where do these bastids hook up? They are all about long enough to reach the driver head light.

Thanks everyone.

Yes I suck, because I didnt take a clear enought shot to tell the secondary color. but You guys are smart enought to figure it out since these are all in the front of the truck. on the driver side.

I cant thank you enough.
 
Hae you looked at the wiring diagram on the tech pages or do you have a Hynes manual. They don't tell you routing, but they do show color codes and when you figure out what they are, or at least what tap they are coming off of, you figure the rest. I am at work, but I remember green as one of the headlight colors. I am guessing from the loaction that some go to your voltage regulator, starter and alt and others might go to your cluster gauges and starter. Not sure though, my 77 has most of the cab to engine compartment wiring on the drivers side and the engine compartment to rear on the pass side.

Get the Haynes manual. it will help you here and you could probably find onetoday. The FSM manual would also tell you.
 
Hey Romer good to see that us true crusier heads are hard at work today. Well hell it's pissin me off cause it's rainin and to hell with work, it's a perfect time to be on the trail. With the top off the rain comin in and the mud washin over the wind shield. Think I'm gonna call it an early day!
 
I have a wife and two teenage daughters. Being hard at work is the only way I can afford a cruiser, actually 2 with the LX450.
 
those don't look original to me.........

I cant recall wiring going thru the firewall up bby the brake master.........
 
I agree with Pimp, those colors may not be OEM, but then, as you say, we can't see the stripes (because you suck! :flipoff2: ).

Anyway. Skip the Haynes manual. It also sucks.

Do you have a chassis and body manual? It has in the back a set of drawings that show the different harnesses and what comes off of them. Won't be perfect, because there were minor variations year to year, but it will get you most of the information. Combine that with your electical diagram, and you should be in good shape. If you don't have it, I can post the diagram and definition page later.

Pimp has FJ40s from a different era, so there may not be a harness there in his trucks.
 
looks almost like an early stereo harness before they standardized the colors.
yellow = constant, red = switched, pair each of green, white, blue, gray for speakers. etc.

I don't know... just guessin'
 
i just looked at mine it is suppose to be a 78 bj40 . my wires are the same color i have 3 white also ,
yellow one has red stripe, two solid green, two green with white stripe ,.2 blue with red stripe and i also have wires coming through the firewall on the passenger also . looks origional to me .
mine might be a 1975 it did come with front drum brakes . it was a parts vehicle with a v8 conversion . it also has a huge (long ) brake booster where they different between deisel and gasoline fj40's
 
I think the red one is to the brake master, the others provided power to the carb and "emissions" devices..

most of them you can just cut..
 
What did you do with the factory wiring diagram I sent you?

You are kidding right???
 
My 9/70 FJ40 has a wire bundle that runs along the drivers side. It goes to the headlight, left TS, side marker, vac valve for emissions, horn, washer bottle(?), brake master cyl

I thank you again for providing me with the information.

i have the Diagram 65swb sent me and figured out some more stuff. However the diagram does not incorporate a set of wires coming out of both sides of the firewall running along both aprons.

In an earier post of mine it was determined by someone that the late 1970 or early 1971 FJ 40s had a wiring set up different from most other 40s. Because it has two harnesses not just one.

I have literally about 6 different diagrams and none of them match what I have im my rig. I have found one from the factory service manual on Birfield.com. But it is too small to properly read. I dont have a computer at home. and the work computers are too locked down to blow up the PDF and print it.

I have read and heard from several people to just cut them or "its easy to figure out" Im sure it is easy when you dont have 7 extra wires and nothing to reference where they go. I am certain these are OEM wires.

I was hoping someone with the same set up would be able to say, the "pick a color" is running to this part in my truck.

The truck has been desmogged and is running a 1975 motor. so I dont know if those are where some of the wires should go. I know a few of them should go to the wipers and washer bottle. The motor runs fine and everything is hooked up to it electrically.

I have the following hooked up: Both headlights, alt, starter, all of the gauges, brake master, carb solinoid, horn relay. and a few others.

The things that are not working or not hooked up that I know of.
Both turn signals, both side marker lights in the front and the driver in the rear, washer bottle, wipers, heater fan, .

So a long explanation to a problem. I would be fine if I only had one harness coming from the passenger side, Because most of the lights and stuff terminate or end at the driver side. However I dont get a good feeling with a hand full of wires not hooked up anywhere.

I cant thank enough people for helping me out by sending diagrams and offering advise. I was simply hoping some one would be able to look at theirs and tell me where they go. I will be back to the truck tomorrow (i hope) and will write down what color combos they are.

I am sure some of these go to emmisions stuff I dont have anymore, so even knowing which ones are emissions related will greatly cut down on the number of unknowns.
Thanks again. Warren.
 
Warren, I asked before if you wanted some of my info. When you didn't respond, I didn't post it.

Here is a map of the L cowl wiring. It is a bit older than our era, so there's slight differences. But most of the stuff is the same. Send me your email and I can send you a full version of more readable quality.
