ECU Pinout Diagrams (How to make sense of them)

[B1NZ]

So I am trying to hook my Monit Tripmeter into the rally car, I have the plug in speed sensor interface wiring thing but I need to connect the 2 wires to the speed sensor wiring, Now I have found the following ECU Pinouts page http://www.jollygreenmonster.com/help.htm And if you look at ECU pinouts and scroll down my car would be the 99-00 Impreza (Version 6 STi)

So are these diagrams of the actual ECU or looking at the plugs that plug into the ECU?

Im guessing I need to connect to B135 pin 26 and a ground somewhere with the other wire? Maybe B134 pin 17?

Thanks in advance

Thems be the plugs in the ECU. So as if you holding it in your hands looking at it

OK, so I found the installation guide for the apexi rsm and it is really handy for what I need, Even shows you what pins and which way to look at them etc... So it looks like I was correct in plug 135 pin 26 but the gnd I need in plug 134 pin 8, According to the guide its the pins as you look at them while holding the ECU (as you said Warwick)

Now im off to see if I can start an electrical fire lol

Or blow up your Monit

What is the speed sensor interface that you have?

We usually wire them straight to the signal without anything.

The monits are a bit fussy with their signal too,
have had some issues with them we we first started fitting them,
but sussed out the reason for it.

The one for the monit, Speed sensor interface or something like that, plugs into the Monit loom plug, Seems to work fine, Are you saying I didnt actually need that part?

[matt dunn]

Probably not.

We have a few at work as we usually find we don't need them.

As long as the signal pulls right to ground then there is no problem.
Just hook the blue wire fron the 4 pin plug directly to the speed signal wire,
and they work fine.

Is yours one that is also GPS capable or is it an older one?

Older one, The T-100 Rather than the G-100 or whatever it is now

If I can be bothered I might try it without then might be able to take it back and exchange it for other stuff I might need
