The "green thing" should be plugged into the green plug u see in the bottom left of the pic.
As mentioned before,"usually" blue/black wire goes to D6 on the ecu & black wire goes to the ground point on your engine,usually thermostat housing.It doesnt matter which wire is connected to which of the 2 pins,2 bits of metal your talking about,its just a switch.So u need new pressure switch"green thing" & a new green plug with some wire hanging out of it so u can extend em to where they have to go.Or u can do a hell bodgy job & try solder some wires to the 2 bits of metal hanging out,but no guarantees on this method.Its no fun at all trying to find intermittent vtec engagement problems.
The green/yellow wire from the vtec solenoid goes into the grey plug,obviously,so u need the grey plug that fits into this plug so u can run the wire back to ecu A4 as u mentioned in first post.U could also just cut the grey plug off & join a bit of wire straight to it if u wanted,without any problems,just insulate the join well with some heatshrink.
-
ok so if im doing a dodgy job right.. i will need too
Vtec Solenoid Wire : connect this wire to A4 on the ECU (or look for wire from this slot and connect to it
Vtec Pressure Sensor : connect 1 wire to D6 and ground one
i aint to worried about cutting plugs off to wire stuff ;D
-
Yes,correct connections.
Theres no prob with cutting the grey plug off & just joining the wire,just make sure its well insulated(like i said heat shrink,not tape,if u use tape put some split conduit over it as well or cable tie the tape on) & support the wire as well,dont leave it dangling by the solder or crimp connector join.
The green plug,try find some terminals to slide onto the metal bits & again insulate it well,but your on your own with this one,I highly recommend u get the proper plug & get a new pressure switch.
If your gonna get this dodgy,I would probably just run the pressure switch terminal D6 to ground & forget about the pressure switch for now ,till u find a new one.Just make sure u keep your oil well maintained & topped up,& dont come crying to me when something breaks
I have seen vtec pressure switches before disabled by software,but i just dont want to be responsible for tellin u to do this.

hahaha aiight
so that covers the solenoid bit
yeh i guess ill buy a pressure switch
when i buy this it wont come with the plug though to the wires right
but i rex i can just run the wires off it? without the switch
ill check it out tnmz and open up the switch to see whats in there..
im assuming its just 2 wires.
one which connects to D6 and one ground!

Yeah youll have to find someone with an old engine harness or cut one off a wreck to get the plug.I might have something thatll do the job,I'll have a look later.

aiight kool, thanks! i posted it on wanting to buy i guess hopefully someone has one ;D
vtec wont work untill this is connect right!

Ok dude,your in luck,I got the 2 plugs,u just have to find the pressure switch.
The pressure switch plug is not pretty green,but you'll just have to cope with grey.
They also only got bout a metre of wire hanging out of em,but at least u'll be able to make a proper join on the pressure switch.
Like I said u dont really need the solenoid plug,but i got if u want.
Also if u search the local wrecker,u'll find a lot of intake manifold sensors,such as IAT,IACV,etc, use the same plugs as the pressure switch if thats easier & the solenoid plug I'm fairly sure is the same as some A/C compressor plugs,so that opens up the possibilities a bit.
PM me if u want mine,however,I'm at the opposite end of Sydney.
EDIT:yes,no vtec for u unless solenoid connected & pressure switch wire from ecu grounded in some sort of fashion.

oo aiight sweet as!
pm sent!  !
btw i got no idea where the pressue switch is?
is this it?
i think this is what im gna do :
Vtec Solenoid : direct wire from A4 on ECU straigt to the solenoid.
Vtec Pressure Sensor : direct wire from one plug to D6 on the ECU, then i will connect a direct wire to ground
ill start it tomorrow morning,
if im wrong please tell me!
only thing im worried about is the pressure sensor im assuming from the photo above, does it matter which one i use as poisitive or negative?
EDIT : ok pm cleared it up for me! thanks! time to look for a pressure switch, but can someone clear up if the wiring im abotu to do is correct?

Doesnt matter which way u connect the pressure switch,it is just a switch,its just joining the 2 wires together.
Yes that is the pressure switch,find a new one.
And yes the connections u listed are correct.
-
SWEET! if you come around to me work later that will be sweet, just be here by 10:30

ehy guys well i wired my vtec i think
the wire from A4 was orange and white, which i followed through to the shock tower at passenger side which i connected directly the vtec wire too..
the D6 wire did the same but was orange and blue which i connected on vtec pressure switch to..
and the other wire to a ground which the engine uses?
both wires directly below each other!
if i should change the grounding? where should i ground it
did this install my vtec? how can i tell>?

If they aren't connected properly you should get an ecu code.
