quick wiring questions (electric fans, id connectors)

[Arrest_me_red]

alright, so my engine is just about ready to go in! Im going to use an electric fan set up that was installed from the previous owner, now this system used an autozone 30amp relay, where the coil was energized through a signal from the diagnostic port, now is there another way to wire these fans? the car should already have a signal wire, relay, and leads for electric fans right? i don't know what these plugs are for but they look like they could be for electric fans

and what are these connectors for? these are on the MA70 chassis

and

other end

and this is on the 1jz, now i know the one with blue tape is for the hydrofan water pump but idk what the other is for

Well, the two in the first pic are for the stock smallish efans, controlled by, IIRC, the AC circuit and ... damn. Something that appears to have fled from my memory at the moment.

1 a/c fans as grim said.

2 proly wont get used.

3 7m fuel injector resistor pack. If your 1j and on 1j 370 or 2j 440 injectors you can ditch that. The little black thing attached is for the stock boost gauge.

4.i dont remember seeing that on my 1jz. Which 1j do you have?

Thank you for the quick response!

this is from a jza70

Alright, so i should use those for my aftermarket fans right?

 

[hvyman]

No. You will need the fans on pretty much all the time or at least temp0 activated or on at no/lower speeds.

Those fans only come on if your a/c is on or if the engine gets too hot like 210*(i think) to pull more air through the radiator.

So then how should I hook up the fans? Should I hook them up to the accessory wire? Where my stereo signal is hooked to.

That way they would run as long as the car is on.

one last wire... where does this go?

 

[hvyman]

Looks like the a/c clutch wire.

 

[Arrest_me_red]

awesome, thats what i thought, but none of the diagrams showed that being a single wire, alright i guess this goes to the no.9 pin of the ea2 connector, im glad thats finally sorted out because i read so many threads about A/C, and none of of them resembled my car lol, it was very frustrating.

Thank you very much!

No that goes to the ac compressor.
