What in the #$%^$@ do these do????

[mk3tattoos]

so i picked up this car half way through with a swap and there are a few thing i need help to finish it up.

first- i found four plugs under the fuse box.

second- is this plug suposed to be used, i cant see were it goes.

third-can i get rid of all these hacked up plugs, they dont go to the fuse box.

fourth- what dose this vac port go to and (and pics help alot)

fifth- also dont know were this vac line goes to, (pics help)

thank you very much for the help! i just want to start it up and drive to work already

In the first pic, the two black plugs are for the auxiliary AC fans, which you probably dont need. The single pin one is the AC compressor clutch switch, and if you want it to work it gets wired to the matching wire on EA2. I can't tell what the fourth plug is, maybe for a relay.

Second pic is the plug for the noise filter (a small black thing that bolts to the fender in that area).

In the third pic the big rectangular plug is for something i've never used. The smaller plug is C1, the factory plug for the engine harness to fusebox connection, it looks like most wires have already been cut out of it and wired to EA2.

That vac fitting goes to the power steering idle up valve.
The last vac line goes to the other end of the power steering idle up valve.

thank you so much juno! for answering ALL my questions.

were do i hook the vac lines up to for powere steering, is it on the rack and pinion?

and were can i find a noise filter, it never came with one?

edit-ok went out to my 87 car that im parting out and found the niose filter on there, can i use that for the 1j

and i found a relay cleaner cont. that will plug into the bigger white plug in the first pick. will that work as well?

 

[JonoTurbo]

The vac lines go to a valve that should be bolted to the pressure line output of the power steering pump. Its a black cap screwed into the side of the fitting with two vac connections on it.

Yeah, the 7m filter will work on the 1jz.

The cleaner control relay? I think that might be for the headlight washers...which 89+ cars don't have (I'm guessing by the wiring that the car with the 1jz is 89+). If you could get me a picture of that white plug from a different angle I might be able to tell you what it is.

it is a black box about 3in big, it has RELAY CLEANER CONT. in the front of it. i think your right about it being for the head lights. here is a pic of that plug.


do i cap off the vac line by the diag. box if im not using the charcol canister, and what else do i need to cap off when not using it? thanks alot!!!!!


i found the black fitting for the vac lines but i dont have the high pressure line that goes to that. were can i get one of those?

 

[JonoTurbo]

Yeah, I don't know what that plug is, where do the wires go for it?

Definitely cap off that line, almost all the 1jz vac fittings are on the intake so just cap anything left over after you hook everything up. Also, make sure you have the map sensor connected to the filtered vac connection on the inner side of the intake mani.

Driftmotion sells a power steering pressure line for the 1jz, or you can go to a local auto parts place and order a line for a 94 Nissan Maxima. It is the right length and size, you reuse the stock banjo bolts to put it on. It runs about $30 around here.

 

[mk3tattoos]

what do i need to do to get these lines to hook up? i know one goes to the hydro fan and the other goes to the oil cooler.


this is were i need to hook up the high pressure line right?
so i need a high pressure line or a low pressure line? when i went to the parts store they wanted to know what size engine for the 94 nissan max. what exact kind of line do i ask for? the lines they were showing me all had to ends for banjo bolts.

thanks a million

The high pressure line comes off of the power steering pump itself, and goes to the steering rack. It has banjo bolt fittings on each end. The pressure line is the same for either maxima engine.

The fittings you show attached to the passenger frame rail are for the power steering cooler. You can use it as a hydrofan cooler, that's what I did with mine since its in the right spot. The smaller line coming from the reservoir on the passenger side goes to the fitting on the fan motor, if you want to run a cooler, you can put it inline with that. I ran mine from the pump to the fitting on the frame rail, then from the other fitting next to it, back to the reservoir. Disconnect the line that's already on the other fitting.

That line is the power steering return line, and its in the wrong place at this point, just like the line in the 2nd pic with the banjo fitting (which is the pressure line). I simply unhooked them both at the steering rack on the other end and removed them.

huh, so stuff is hooked up wrong already. can someone put up pics of where things are suposed to look like and what hook up were. just so i know i am on the right track. that would help out alot.

so were does the hose from the res on the driver side for the power steering go to, if it does'nt go to the fitting with the black end with two vac ports on it.

 

[JonoTurbo]

The smaller of the two hose connections from the power steering reservoir goes to the return line connection on the power steering rack. The bigger line goes to the power steering pump, there should be another fitting on it above where the pressure line fitting.

The power steering lines are all messed up because on the 7m, the power steering pump is on the passenger side of the car, and its on the drivers side on the 1jz.

EDIT: Also, make sure you have extended the big black wire from the alternator, since its also on the opposite side of the engine bay from where it was.

 

[mk3tattoos]

alright! starting to understand what needs to be done also found these in a box, are they usefull?

i have the alt. all hooked up.

juno, you are awesome. thanks for helping me out so much. i cant wait to put upp some video of this thing driving down the road!!!!!

 

[destrux]

Sweet. So a maxima PS line fits? I keep learning stuff for this swap everytime I come on here. Just saved $60 with that tip. I can get a used maxima PS hose for like five bucks at the u-pull-it. Thanks.

 

[mk3tattoos]

got everthing hooked up! thanks for all the help juno i will put up a video of it running soon. for now here is a couple of pics.

 

[JonoTurbo]

Looks good, that's a clean engine! If you still need a throttle cable that fits one from a 92-96 camry or corolla works well. (Didn't see one in the pics)

Btw: It's JonoTurbo, my name is Jon haha

 

[mk3tattoos]

Sorry Jon, lol. I'm using the jza70 cable for now, but I will get one from the camry asap!
Thanks for everthing


were dose this vac line thats highlighted in red go to? its the last of them and then i can start the car
found it hideing next to this one, but i dont know were this blue plug goes!!!!
