Perfect. Thank you again Zaphod, can't say that enough. If ever in this part of the world feel free to stop by and drive the **** out of my car.

need to trace all the wires on the 16 pin connector back to teh pins on the DB37s respectfully.



once that is done, figuring out what wire goes where will be easily.

I kinda remember making this, where someone was upgrading from a DIYPNP and he wanted me to make his 16pin connector the same.

looks like there's at least (2) 12v sources, (2) grounds, Spark C, Spark D, VICS out, WBO2 in, EBC OUT, Knock IN, maybe Tachout is the last, under sure why.

Zaphod

Hi I think this snipplet gives us the best starting point:



@Jeff - Please post close up pics of that 16pin connector (back) and as Brain said try to see, to which pin on the DB36 connectors the wires are going.

@Brain - I think you missed the two extra injector outputs.

I would be interested to see, how the original owner managed the connection on the two injector connectors (3/4)

Came out of a 1.8L car right? Don't see why it would be running batch injection on a car setup to run seq.

Zaphod

Yeah, but the car itself was a 93 including the wiring - so there have to be extra wires for the seq. injection - or am I missing something...? And you can see in the DB15 pinout of his DIYPNP that he had 2 extra injection outputs on that DB15...

Braineack

oh maybe not, this is why you gotta trace the harness wires back.

i cant tell if 4Y and 4Z are populated. Doesn't seem to be enough wires on that 16pin to cover it all -- possible it doesn't have any seq. injection outputs populated. dunnoz

Zaphod

O.K. so Jeff the Brain has spoken...- you know what to do - make some good pictures, trace the wires and do a little spreadsheet pin on the extra connector vs. pin on DB36 MS3 or MS3X

Jeffbucc

Can do.

Braineack

iTrader: (62)

yeah cause if you're like: the pink wire on the connector goes to pin-32 on the lower db37. I'd be like: okay that's the fuel pump out.

Zaphod

Yeah but that is because you are:

Braineack

or i have a handy spreadsheet that lists all the ms3 and expander pinouts?

Jeffbucc

I'll take it but I'll also make a spreadsheet of the pin connectors for you as well.

Jeffbucc

OK Brain, finally got some good pictures of the board for you. I hope this helps.

Pins are labelled as followed

2A 2C 2E 2G 2i 2K
2B 2D 2F 2H 2J 2L





2A 2C 2E 2G 2i 2K
2A-Brown(PIN35)
2C-Red(12VDC)
2E-Orange(IAT)
2G-Pink(02)
2i-Yellow(Coolant)
2K-Green/Yellow(IAC2-A)

2B 2D 2F 2H 2J 2L
2B-Blue(TPS-SIG)
2D-Blue/White(Blank)
2F-White(Blank)
2H-Black(Blank)
2J-Brown(Blank)
2L-No pin in connector


This harness has an odd single pin connector coming off the harness. It is the black wire between red & grey.



The harness goes into this lower port.

I'm still not following where the wires in the first pic end up.

the only thing I can tell from the pics is that

2E and 2G are grounds. That's it. Your pinout listing below the pics doesn't make any sense to me.

you have to trace the wires from 2A-2L all the way back to the harness they are in.

Jeffbucc

So you want the wires that are soldered to the BOARD rather than to the connector?

The wires on the connector are the ones I paired with the board pinouts.

2A 2C 2E 2G 2i 2K
2A-Brown(PIN35)
2C-Red(12VDC)
2E-Orange(IAT)
2G-Pink(02)
2i-Yellow(Coolant)
2K-Green/Yellow(IAC2-A)

2B 2D 2F 2H 2J 2L
2B-Blue(TPS-SIG)
2D-Blue/White(Blank)
2F-White(Blank)
2H-Black(Blank)
2J-Brown(Blank)
2L-No pin in connector


If you want the actual BOARD wires, I can get that later tonight. Sorry Brain, wasn't sure exactly what you needed.

Jeffbucc

And I am starting to think the labels on the connector wires mean jack ****.

Braineack

iTrader: (62)

did i not say that like 16 times now?

i need to know where the wires INSIDE the Bob go.

so the green wire on 2A and green wire on 2C and white/blue wire on 2I, etc.

Jeffbucc

OK OK, I just like to sixteen check things to make sure

It shall be done.

Braineack

iTrader: (62)

cause then once you do, and we know where the wires on the harness go back to the ECU, we can connect dots and properly setup a msq for all your i/os

Jeffbucc

OK Brain here is your info...I hope it helps!

2A 2C 2E 2G 2i 2k
2B 2D 2F 2H 2J 2L

Harness wiring

2 Green Wires———— 2A/2C
2 Black Grounds——————2E/2G
White/blue=IAC1-B—-2I
Purple=Fuel Pump—--2K
Grey=TPS-VREF——2B
Pink=02——————-2D
Blue/white=IAC1-A—--2F
Green/white=IAC2-B—--2H
Brown=PIN36—---------2J
no wire present———2L

I was trying to find IAC2-A and found it on 1G

The 2 greens on 2A 2C terminate on the end of the board but there are no markings on the wires/board to indicate why.
