1983 Toyota FJ40 missing connection (1 Viewer)

[leotxbr]

Hi,

I am new here. I am trying to figure out what these wires and connectors are for, and what do I connect them to on a 1983 Toyota FJ40.

I am asking about the connector on my hand, not the one for the washer fluid pump. I removed the washer and the radiator tanks to take this picture.

Also, if you have a good colored wiring schematic of the 83 fj40, please post a pic or PDF here. Having trouble finding a decent one.

Thank you for the help!

If you don’t find where it plugs in you could blow the head gasket.
Exceed with extreme caution !

You can find a wiring diagram here - not in colour though, so you'll have to read the colours.

What color are the wires to that connector - is it the front turn signal / side light?

Your headlight connector needs closing up.

Check specifically (and verify diligently) if its the A/C connector (add-on which is probably not present in your 40). I have
a similar unused connector in my 79.

There is an add on AC in this one, and a black wire ran to it. The car runs perfectly, but the AC does not.

Wires are green red and black.

Yeah, wires in this FJ40 was not done very well.

The only solid green wire is the side light / tail light feed, but I'm guessing that this one is bespoke.

The red and black are probably +12v and ground respectively - you could try pulling fuses to see which circuit its on.
The green is maybe tapped into an existing circuit to provide s switched input (for a headlight relay for example). I'd unpick the trunking and see where it goes - probably ends up under the dash somewhere.

I also have a 83 fj but mine goes into a black end that locates right by the passenger headlight.I not sure what the vacume pot or what ever that piece is but I also have real toyota a/c.You may not and would guess part of the a/c system.My a/c still works oqwned this for years never tyried it until my son said check it.I always have roof off but amazing just added a can of coolent which works with R12 and wow very very cold a/c.I have only 60,000 miles rust free as well

”If” that’s a Nippondenso optional A/C system, it would have a single wire (black&white) to the magnetic clutch.
