Mystery Connector (2 Viewers)

[skeeter1]

I bought a 1996 80 series from a buddy (who was a Mud member, owner before him was a member as well) last October, and this forum has been a great resource since then. Decided it’s finally time for a post.

I was replacing my battery today, and found this connector laying in the bottom of the battery tray. I can’t find anywhere obvious that it should go. Does anyone have any ideas? I read through a thread listing all of the main harness connectors, and didn’t seem to find a match. Thanks!

I'm sure someone will know exactly what that goes to, but in the meantime there should be a 5 digit number somewhere on there. Probably very small. But Google that when you find it.

Looks like it could potentially be aftermarket. I don't remember seeing a connector with that orange retainer. But I'm not expert!

Edit: knock sensor?

Thanks for the reply. Could be aftermarket, I don’t see a number on it.

I replaced one of the knock sensors right after I bought the truck. If I remember right, there are 2. I’ll inspect tomorrow, although I’m not getting a knock sensor code.

Oh I'm sure that is a leftover if it was inside the battery tray. No way for something like that to get in there on its own.

Could be for the ultra-rare electric motor pop-up headlamp option, like on early 80s Corvettes??

OK, probably not, but it's not a knock sensor connector from a 1FZFE.

What's that bar sticking out of it??

Haha, good guess.

The bar sticking out of the center of the connector is the terminal with a little bit of old plastic stuck on.

It’s also got a couple of plastic tabs sticking off the housing.

X2 on 'not a knock sensor' connector.

Kinda doesn't look Toyota

Looks a lot like this one:

FYI, that picture I showed is the plug for the ECT (for gauge) illustrated below:

Looks like that could be it. I’ll check it tonight. Does ECT stand for Engine Coolant Temp?

If so, my gauge is working. Maybe someone swapped it in the past.

I assume so.

Confirmed it was the ECT. Thanks everyone
