Hi,
Trying to identify this box, with wire harness. Tried searching on toyodiy, partsouq, Internet search and nothing thanks for the help. I thought it came from my 85 HJ75

Glow plugs have two relays?

It's an AC amplifier.

It's an AC amplifier.

That’s what I was hoping for.

Pops right up if you google the number, FWIW.

I didn’t use Google, I used DuckDuckGo and nothing came up

Are AC amplifiers and glow plug relays so visually similar that you can't tell by looking which it might be?

Well we needn't fear AI just yet then.

Take a look at this thread: What part is this? - https://forum.ih8mud.com/threads/what-part-is-this.1027542/

This shows the electrical connectors which are clearly for an AC amplifier. Glow controllers do not have a separate power terminal as the power switching is done by relays (usually) in the engine compartment.

Within this example: yes.

Well we needn't fear AI just yet then.

In general, I don't...but it definitely gives some scary-smart moments.

Now, what's scary is that I used the images from the linked thread in a new GPT prompt, and this time it came back with "likely an AC amplifier, as indicated by the power terminals."

So, I guess it really is easy to tell just by looking, as long as you're looking at it in situ, or you have the remainder of the visual information that you need.

there is a glow plug timer but couldn't find any pictures of it. also the wires coming off of this has one set of wires that are terminated/taped off instead of ending in a plug, so it is one plug short for plugging into the AC box under the dash.
