Toyota Ecu's

[97paseo]

ARRGGHH!!

I need to know which colour wires do what basically, anyone know if Toyota use the same colours for everything on their ECU's?

If they did Haynes manuals stuff would be so much easier....

[Bibbs]

What wires are you after?

[97paseo]

Erm...which ever ones the A'pexi RSM requires.

Got a feeling this isn't gonna be easy!

[Bibbs]

I had to take the cover off my ECU .. the correct pins are labled on the PCB ..

[97paseo]

It's four wires, Power & Ground, RPM & Speed, then theres the G-Sensor...

[Bibbs]

those four are printed on the PCB on my ECU ..

[97paseo]

Ok thats good news, perhaps mine is the same.

If only it was in the car & working!

[Bibbs]

Revs is black

Speed pulse is purple

Others can be taken from your headunit ..

[97paseo]

Are you sure? Thats great if so!!!

Turns out the ECU diagram I have is for a '94 car. I doubt Toyota will give me a copy of my one will they? :(

[Bibbs]

This was correct for mine .. but I checked the PCB and one had "REV" and the other "SPD" or something ..

I've got an AVCR here .. just arrived ..

What's your engine? Does it match any of these?

Aristo,Soare,Supra,MarkII,Cresta,Chaser, Mr2,Celica,Cardina,Starlet ?

[97paseo]

No.. :( Engines the 5EFE which isn't listed on the RSM instructions.

Somone on PaseoPIMP said they'd looked in their ECU before & it doesn't tell you whats what, mind you that might have been a 1st Generation Seo.

Erm - 'Nightmare!'

[Bibbs]

I've only got the following

2JZ-GTE (you wish)

1JZ-GTE

7M-GTE

1G-GTE

3S-GTE

4E-FTE

2E-TE

Can you tell me what the plugs ar that go into your ECU ?

the MR2 for example is 26pin, 16pin, 22pin .. for the 3 connectors.

[97paseo]

Yea those are the engines I've got but I've seen one in a Rover & Gen7 Celica so they must fit!

I have no idea how many pins it is. :( I can't get to it without taking the glove box out!

Could take a macro pic of the wires I can see coming out of it - dunno if that would help.

Me thinks I should have looked properly at this before ordering...

[Bibbs]

Have a look at the colours going into your dash ..

I'd have thought they'd be the same colours as I listed ..

[Bibbs]

In google .. Tercelonline.com keeps popping up .. same engine?

[97paseo]

Yea good idea I'll post there as well & have a look at the wires.

Thanks for the help on this!
