I've just got to hook up mine to the ECU but i thought i'd better check my facts out.

Now everybody must excuse that the pic quality is crap and it is massive
I'm thinking it's the block on the right?

 

First rule of posting - tell us the MY

Is that a AE800/AE801 ECU? Does this help?

Stefan

 

3500+ post and i can't remember that

MY99/AE800

 

That link should sort you out then

Stefan

 

I fitted Defis at the weekend and one simple little wire has me stumped
I've read a load of threads on the fitting of AFR's but i can't seem to relate any to my ECU as i look at it.

 

...........including that one

 

Quick somebody - Before the mods catch me in general

 

Have you look at the MRT pdf? it has the wiring for a LHD ECU.

Also this old thread of John Banks?

The large blocks are B134 (black), B135 (gray) and B136 (blue). So, that would be pin 21 on the blue connector for your ECU.

Can you confirm what colour that wire is on your ECU?

Stefan

 

Caught and Your Outta here!

 

Brun,

I'm off to the Gym. Can you manage on your own

Stefan

 

Light green with silver spots.
Thats assuming you count from the top left wire?

 

judging by other posts i've read, the wire should be white with silver spots

 

Haven't read about a light-green wire anywhere on the AFR posts

Yep, everyone mentioned white with silver spots.

When was your MY99 registered. Mine is from May, so I can have a look at mine and let you know what the colour of the wire is.

Stefan

 

December 1998.
Trust me to be different

 

A better pic

 

Up

 

I've sent an email to Scoobymania too.
Someone has to know.
The upside of this is that while the AFR has power, it just reads rich all the time

 

Well everyone keeps saying it's Pin21 on that block. The pins the same for the majority of the ECU's, but the wire colour does depend on the MY. I think yours is different because it's a late 98 (early 99) model.

What about doing a continuity check with a digital multimeter? assuming the wires for the probes are long enough to stretch between the O2 signal wire and the ECU.

I guess what you need to know is which pin on a AE800 is for the O2 signal. If that happens to be green on your cars wiring loom, then so be it.

Can't believe no one else has responded to your post ; just this useless c*nt

Stefan

 

Do you think i should just tap into it and hope for the best?
Thanks for all your help.

 

hmm, I'd be a bit wary taping into any wire's unecessarily although some lecky tape around any exposed wire would put it back. Trouble is if that doesn't work, then which wires next??

Personally, I'd do a simple continuity check too make sure the signal wire on the lambda connector (disconnect it from the sensor) in the engine bay is actually going to that green wire for your ECU.

If the probes don't reach on your multimeter (you do have one?), then use some spare wire to extend them.

That should tell you for sure.

I'll give it a try!

<Brun the electrical muppet once more gets out the multimeter>

 

If you secure one end of the probe to the O2 connector's signal wire, then you can probe more of the pins on the ECU block (if the green one doesn't work). If the multimeter beeps at you, then you've found the golden ticket

Stefan

 

***NEWSFLASH***

The two wires off the llambda connector are white with silver spots and yellow with silver spots
I think the multimeter job is gonna take another pair of hands, so i think i'll have to wait till someone can help me

 

Do you have a few metres of thin wire left over from the AFR install?

I ran two cables for my SPA gauge, but forgot to mark which was which and put them through 2m of trunking from the engine bay to my a-pilar.

I stripped both ends of some spare wire to expose about an inch of copper and wrapped this tightly around one end of my multimeter probe. The other end I wrapped around a paperclip and stuffed that into the socket on the first wire I wanted to check. That effectively extended the cable from the a-pillar into the engine bay. Then I just used the other probe to check which wire it was. It takes a little time to set it up, but it worked for me.

Stefan

 

I'll see what i can do

 

Brun,

Any joy m8?

Stefan

 

I'm gonna have a look on Saturday I'm doing a bit too much overtime this week to be bothered.
I'll let you know

While i'm here! There are two wires off the lambda sensor, if one goes to the ecu, then where does the other go?

 

I maybe wrong (so best check with others) but I think the ECU has signal wire & sensor ground. There was a
argument (sorry discussion) on whether you should connect an AFR meter to this ground on the ECU or direct to the battery.

Details on the ECU wiring is at the bottom of this post.

Stefan

 

What is all this waffle about then?

Just get the Link ECU manual and locate the pin by checking which way around you are compared to the diagram.

I never try to remember the colours

 

Don't foget that most of the info you have seen relates to looking at the back of the connector not the front so pin 21 is on the other side of the connector not where you have indicated.

Look into the ecu, its on the lower right side.
