I'm having one heck of a time finding any info on these things...

I spent roughly 4 hours searching everywhere I could think of for any information and this site had the most available but it still didn't have what I needed.

https://www.scoobynet.com/lighting-o...ml#post8569873

Was the closest I came to finding what I was after, but my connector is only 12 pins instead of the 25.

What I'm trying to do is hook up the oil pressure and oil temperature senders to the psi3. If anyone could help me out, I would GREATLY appreciate it. No one in the states knows anything about these.

Thanks to all for your time.
Matt

*edit*
Also, I've read the manual .pdf and it doesn't have what I'm looking for. I'm looking for a pinout for connector 2.

 

Hi mate,
You don't say which model you have but these are the connections for the later VFD display units.

Only make connections with the ignition switched off and the communications connector disconnected from the vehicle.
Connector 1 is a 5 pin and connector 2 is 12 pin viewed from the back of the unit pin 1 is on the left for both connectors and pin 5 connector 1 and pin 12 on connector 2 will be on the right hand side.

Only make connections with the ignition switched off and the communications connector disconnected from the vehicle.
CONNECTOR 1
PIN 1 – COMMUNICATIONS (TO OBD CONNECTOR PIN 7)
PIN 2 – RX
PIN 3 – TX
PIN 4 – POWER GROUND (TO OBD CONNECTOR PIN 5)
PIN 5 – POWER POSITIVE (TO OBD CONNECTOR PIN 16)
CONNECTOR 2

PIN 1 – WARNING AND SHIFT LIGHT DRIVE

PIN 2 – NC
PIN 3 – NC
PIN 4 – NC
PIN 5 – SENSORS GROUND
PIN 6 – GROUND
PIN 7 – +5V SENSORS
PIN 8 – OIL TEMP SENSOR INPUT
PIN 9 – OIL PRESSURE SENSOR INPUT
PIN 10 – BOOST SENSOR INPUT
PIN 11 – FUEL PRESSURE INPUT

PIN 12 – E.G.T. PRESSURE INPUT
From what i remember oil pressure has 3 wires which go to pins 5, 7 ,9.I cant remember the colours on the pressure sensor though.
Oil temp goes to pins 7 & 8. Makes no difference which way round the temp wires are connected.
Hope that helps
Stu.

 

Stu... if you weren't across an ocean from me, I'd hug you.

Thanks a million man. I wasn't having any luck finding anyone who knew about these.

 

Tried hooking it up per those directions and got nothing.

I ran the plugs and pin 1 is a 12v and pin 10 is the 5v.

I pulled the box apart and it appears that it is a v12vfd.

 

Hi,
Have you got it working now? I downloaded the connections guide from the psi3 website about 4 years ago so it is possible they changed the connections or maybe the US model is different. Unfortunately it seems psi3 are no longer trading but if you need any further help i will see if i can find any further info for you.
Stu.

 

Unfortunately I haven't got it working. I've got the box itself working vie the OBDII cable, but I can't get the oil pressure or temp sensors to read. Which is what one would expect trying the wrong diagrams.

I really appreciate your help Stu.

 

Hi,
I have had a look at my unit and the temp sensor is connected to pins 5 and 8 the pressure sensor is connected as follows Black wire to pin 5 Red wire to pin 7 White wire to pin 9. Are you using Defi sensors? As that is what the unit is designed to use.
Stu.

 

Yes, I am using the defi sensors.

But it seems as though my pins are different from yours.

I will try hooking the wires up that way again but I was not showing voltage to any of the wires.

Do I need to tell the unit some how that it needs to be looking for the sensors or should it pick up automatically that they are hooked up?

 

Hi,
Now you mention it there is a set up menu and you may need to tell the unt which sensors are connected. I know that on mine pins 5 & 6 are sensor ground connecions, so you could check that with a meter the only other thing i can do is check all the pins on mine with a meter and see if any have a voltage reading. But i can't do that till i get home tonight.

 

When I checked them with a multimeter I wasn't showing anything that was grounded, which both concerned and confused me...

Ill hook them up tonight and run through all of the menues to see if I can find a setting for them.

 

Hi,
You do have to turn on the sensors in the set up menu. if it still doesnt work you could try checking all the pins with a meter again and post the readings or pm them to me and i will see if i can make sense of them.
Stu.

 

Any info on how to do that exactly? I looked at lunch and didn't see anything completely obvious.

 

On mine there are 4 buttons on the right hand side press the top 1 which is labelled enter then scroll through the pages using the arrow buttons to page 4 "user options" press enter then scroll to oil temp and see if it states fitted or not fitted press enter to change status and do the same for the pressure sensor then press escape.
The image is of a vfd monitor is yours the same?

 

Wont let me attach the image

unfortunately not...

Back to square one then.

 

I've got some of the manuals and fitting guides for the sensors on my home email. PM me your email address and I'll get them over to you.
I'd imagine yours is a VFD one also, from the part number. So it must be Version 12 with the VFD screen. Maybe the faceplate looks different because they were custom ones about.

 

Sorry about that, hope you can get it sorted.
Stu.

 

PM'd. Looking forward to hearing from you.

You tried Stu, not your fault I have an older version.

 

Clutching at straws now is it one of these?
If not do you have a pic?

Pretty sure that's it Stu.



*edit*
That's the only pic I have available, obviously the first screen showing the model number and all that would make it a bit more useful. lol

 

Hi mate,
Might be getting closer now i have 1 of these buried in the garage somewhere i changed it for the later model in 2006. Anyhow here are the connections for this type of monitor.
(CONNECTOR 1)
PIN 1 - COMMUNICATIONS (TO OBD CONNECTOR PIN 7)
PIN 4 - POWER GROUND (TO OBD CONNECTOR PIN 5)
PIN 5 - POWER POSITIVE (TO OBD CONNECTOR PIN 16)
12 pin (CONNECTOR 2)
PIN 1 - WARNING AND SHIFT LIGHT POSITIVE (+12 Volts output)
PIN 2 - WARNING AND SHIFT LIGHT GROUND (-12 Volts Out)
PIN 3 - WATER INJECTION RELAY POSITIVE (+12 Volts output)
PIN 4 - WATER INJECTION RELAY GROUND (-12 Volts Out)
PIN 5 - SENSORS GROUND
PIN 6 - SENSORS +5 V
PIN 10 - OIL TEMPERATURE SENSOR INPUT
PIN 11 - OIL PRESSURE SENSOR INPUT

OIL PRESSURE CONNECTION
RED WIRE ------------- CONNECT TO CONNECTOR 2 PIN 6
WHITE WIRE ------------- CONNECT TO CONNECTOR 2 PIN 11
BLACK WIRE ------------- CONNECT TO CONNECTOR 2 PIN 5

OIL TEMPERATURE CONNECTION
RED / BLACK WIRE -------- CONNECT TO CONNECTOR 2 PIN 10
BLACK WIRE -------- CONNECT TO CONNECTOR 2 PIN 5

Hope this works, i will find the instruction manual for it at the weekend, pm me your email and i will send them to you as a pdf file.
Stu.

 

^ I like it that it has the 12v on pin #1!

Can't wait to get off work to try this.

Thanks to the both of you for helping out an outsider who joined this forum for nothing more than information. This community is awesome worldwide.

I would stay and kinda lurk, but I know that EU stuff has no bearing on US stuff.

Stu, I will PM you my e-mail.

 

A million thanks to you Stu, the last one you posted worked! I would still LOVE to have any/all manuals you have whenever you get around to it.

Thanks to you as well Joey.

 

hey guys, how did you wire the sensors to the back of the unit? i have the defi sensors ready just need to know if you cut them to wire them up? did you use any sort of connectors etc?

 

Hello

I also have a PSI3 Data Monitor which has decided to not work, does anyone know of someone that can fix these?

Cheers
