Does anyone know where this wire goes in the engine bay? It was tucked under the intake manifold and I'm not sure if this is supposed to be plugged in somewhere or it's for something that my car doesn't have? 1986 22re all stock.

 

My guess is it goes to the AC idle Up VSV that is usually mounted to that right side front bolt on the valve cover. Don't see a VSV in the pictures.
Does your truck have AC?
In this video you can see the plug is square on this truck. Seen other shapes too.

Yes, I do have factory AC.

 

I don't see the Idle Air Control valve that attaches to the intake manifold. Looks like there is a plug.


Nor the VSV mentioned above that connects by vacuum lines to the Idle Air Control Valve.
On this VSV you can see the plug looks like it matches the one on that wire.



You can see both on my 86 22RE w/factory AC

 

Interesting... I definitely don't have that part and the AC is there and works just fine.

 

That system just kicks the idle speed up when the AC is on. Mine is usually around 1100 RPM. Guess that keeps the compressor spinning at the needed RPMs to cool properly. Mine sometimes does not kick up and AC works fine.

Did you buy the truck used? Maybe the previous owner removed it for whatever reason.

 

I did buy the truck used and don't know the history. Weird someone would remove something like that. Everything seems to run fine without it so I guess I'll just leave it unplugged. Appreciate the replies!

 

Might be an aftermarket AC. I think the private distributers like southeast and Gulf may have had their own kits.
if you go to Toyota.com and look under the OWNERS tab there’s a place where you can enter the vin and get info on the vehicle. Sale date, factory accessories, etc.etc. It won’t include anything added by the dealer, though.

 

So if you didn't get the AC from the factory the wire would still be there? Makes sense then it could've been added later without tapping into that wire.

 

The vast majority of trucks were shipped without AC. I think only SR5 units had them installed during production. Sometimes they were added at the US port before being transported to the dealer, but more often than not it was dealer installed. The import tax was (actually still is) pretty high on trucks and commercial vans, so the more stuff left off during production in Japan cut down on the tax owed. It’s also why most trucks even today are North American built, regardless of the brand.

The kits were awesome, though. Had 100% of everything you needed, all Denso components. Exactly the same as if it were factory installed. And yes, the wiring was all there (for the most part) to just plug components into the existing harness. That was true for 99.9% of the accessories Toyota offered. Clocks, lighters, radios, speakers, ac, all had the wiring in place if the new owner wanted to add and simply plug in.
The private distributers often did their own thing, though. So I could see them sourcing their own kits. It was actually a pain trying to figure out what they did at times, as we had no catalog listing their "official Toyota" modifications (or where to order). Toyota has bought up the private distributorships whenever they had a chance. Only two privates are left these days

 

Off topic, but would the wiring for the factory cruise control components be there for a Japanese manufactured 1986 SR5 truck? Mine didn't have cruise and when I bought I was told by the dealership it could not be dealer installed. Just curious

 

Thanks for sharing! Really cool info!

 

No. Cruise control was never something you could easily add on. It wasn’t considered an accessory by Toyota. So wiring harnesses (looms) were either made for cruise control, or not. There were aftermarket kits readily available, but they were pretty hokey, imho.
Later on (mid nineties)Toyota did come out with cruise kits. You’ll spot them because they had kind of a weird stalk coming out the column. It was flexible iirc. They were ok. Not as good as production line units, but better than aftermarket.

 

Thanks. I couldn't find hardly anything on factory cruise.
