18RGEU Wiring Woes (56K BWARE) *It was alive NOW DEAD*

[The Witzl]

Ok alot of talk but no one seems to be able to answer my question about the AFM pins.
Is the order on the Wiring diagram correct in coresponding to the pinouts on the AFM. So is this right:

** pic was here**


? I have 4 wires that im fairly sure about, but I have three that went nowhere on both looms that I had.

Cheers, Bryce

No no no...

AFM WIRING

looking at the connector on the AFM itself, from left to right you have:

E1-Fc-E2-Vb-Vc-Vs-THA

E1 - earth for Fc
Fc - fuel control switch, turns on circuit opening relay (fuel pump relay)
E2 - earth for AFM
Vb - to Vb pin on ecu
Vc - to Vc on ecu
Vs - to Vs on ecu
THA - air temp sensor, to THA on ecu.

ok so is this right? or have i got it back to front?

[The Witzl]

well depends if that is the right way up for how the plug is plugged into the AFM.

If it is, then you have it correct

[Spectre]

Ok, have been laying out all the wires to get the right lengths in the bay before i start soldering. Have one or two more questions.



This is a earth correct?



The dark blue plug in between the injectors is?



where abouts do I plug into the starter?

[WDE_BDY]

Dark blue plug looks like cold start injector, start will have a small spade terminal on the solenoid at the top.

1. Not sure which wire you're referring to?

2. Blue plug is the idle up valve.

3. As mentioned there is a spade terminal on the starter solenoid.

In the first picture, its the black plug in the middle of the shot.

The idle up, where does that connect to? as I cant find it in the wiring diagram.

[WDE_BDY]

Aha, that would be the cold start. You can see the fuel line running into it.

The idle up, where does that connect to? as I cant find it in the wiring diagram.

I'm pretty sure it just needs +12v when the ignition is on.

[RA35GT]

As has been mentioned mate, the black plug is the cold start injector plug.

The blue plug is the auxiliiary air valve (it introduces extra air when the engine is cold) it just needs a +12V when the engine is running...so it can be run off the switched main relay line. I'll have to update the wiring diagram with this as well...

Here is an excerpt from the AutoShop 101 Toyota PDF's


As others have said there is a spade terminal on the starter motor, I've attached a picture to assist you mate.

Spectre, if you are still having dramas, please see this thread:

My loom and ecu and AFM are now up for grabs.

PMed Witzl.

[The Witzl]

too late sorry - you were beaten to it.

[Spectre]

Bugger. Still chasing a full complete diagram...

Hey mate, ha, looks like a mess, just get a time to come round and ill pin mine out with you, just finished mine, u know where to find me
