Electrical Help

[baja1d]

I'm having some trouble with my 1964 FJ40 lights. After some advice I cleaned all of the grounds and discovered that the PO had attempted to wire in some trailer lights. With the grounds cleaned the lights were still not working. I Then cut off the trailer wires and discovered that all of the PO's connections were nothing more then twisted wires wrapped w/ electrical tape. I thought that this was my issue so I made some good connections and still no positive results. I'm pretty sure that I don't have the wiring combination correct even after looking at my wiring schematic. So here it is:

Running to the rear of the vehicle is four wires:

1. Green with yellow stripe
2. Green with red stripe
3. Solid green
4. Green with white stripe

At this point I'm pretty frustrated. Can anyone tell me the combination of these 4 wires. This is what I tought it was:

1. Green with yellow stripe (Stop lights)
2. Green with red stripe: (Head lights & Left Turn signal)
3. Solid green (Ground)
4. Green with white stripe (Head lights & Right Turn signal)

With this combination, everything works except my rear amber lights when the headlights are on. BTW I've posted this in the regular FJ40 forum. Here's the link:

Unless you have a Australia model FJ40 there are no amber lights on the back. Just a round red light light with dual elements. Post a picture of these amber lights. The tail light wiring harness goes thru the firs wall on the far rights side. Unplug it there and check for power on the plug end coming thru the fire wall. It will tell which way to look for a problem.

Sounds good. My mistake on the amber, they are red.

let me find the FSM wiring diagram, one sec, photo soon

let me know if this helps

the GY ( green & yellow )wire on the passenger side controls the passenger side blinker.
The GO ( green & orange ) wire on the driver side rear controls the driver side flasher.

The solid green on either side i believe is for running lights.

Solid green also controls the license plate light :0

oh and btw, the GW wire that is near the license plate light, that is your trailer brake light, for if you are running a trailer

Thanks fellas,

Nice and bright. After hours of cleaning and trying different combinations of wires Destin's post got me thinking about my tail lights. I didn't remember seeing a ground wire on one of my 300+ trips down onto the creeper so I thought I'd take a closer look. As it turns out, there is no ground wire because they're grounded through the mounting bolts to the frame. Apperantly after 47 years they can become very corroded. I'm not sure if this was my main issue because of all the other corrective actions I took but it's very likely. If there is a "next time" this is where I'll start and I'm confident that it will only take a couple of hours rather then a day and a half!
