wiring help

[hiluxmad]

Does anyone have pics of what the check conectors on kdogs wiring diagrams look like or could tell me where to look? also where is the fuel pump speed control relay and what does it look like?
Any help would be much appreciated.
Im tryin to make sure i have every thing i need before i send the leftovers of the cut to sydney for one of the other members.

Found a Soarer at a wreckers today.
Got the FPC out of it.
I paid through the nose @ $75 but meh, means it all wires up as per factory.

hiluxmad, This pic may help the controller it is usually between the rear of the passenger door and the wheel arch next to the rear seat, just below the window.

thanks lambo, but i think iit is different on the crown cuts and i only have front cut. apparently it is under the bonnet somewheres.

 

[Guts]

Shouldn`t need it anyway.

check connector is on drivers side under steering wheel some where, also one under bonnet, fuel pump speed relay is in the box under hood with all them other ones, it just switches a resister which is alloy box mounted near relay housing, it is not needed

 

[hiluxmad]

do i need check conectors?

 

[Guts]

If you are talking about the diag plug then you only need one, the one mounted on the motor, the other one under the dash can be deleted.

 

[hiluxmad]

good point guts. are the check conectors the diagnostics plugs/

 

[hiluxmad]

does anyone know if the check connectors on kdogs diagrams are the same as "diagnostics plugs"?

 

[Guts]

Ya I think they are, easy way to double check is to just look at the colour of the wires and the wire colours on the diagram.

You'll find the check connector or Diagnostics plug on the engine doesn't need any wiring as it's integrated into the engine loom on the engine. Don't worry about it.

The engine check light will need 12v switched power but that's about the only work you need to do on the diagnostics side.

Don't worry about the one near the steering wheel it gets left behind with the rest of the chassis loom.

cheers rod+guts that clears a few things up.im not running the check engine light anyway so it doesnt matter

hiluxmad - it's a good idea to maintain the check connectors (aka - diagnostics ports etc etc) as they have a couple of connections on them which are very useful for EFI diagnosis BEYOND the simple CEL error codes from the ECU.

THe biggest of which is serial data. THe ecu actually gives out serial data which indicated what it is doing based on the sensors/signals it is reading whilst operating.

I just think they are a good idea to keep. The two in the UZS131 that i'm aware of are just above the accelerator pedal in the underdash trim, and another in the engine bay attached to the intake manifold..... **oops just noticed this was already posted**

i agree that you really only need one of them, especially considering the in cabin diagnostics connector is part of the chassis loom and annoying to rewire!


P.S. hope all is going well with the conversion!!!

The Witzl,

I'm not sure if you're aware but Toyotas readers don't work on Crown engines. They can check an LS400 delivered to Trinidad but not a Crown.

Workshops with "Mountain Equipment" It's a common proprietery brand, can read the ports.

Sorry for the late reply, but here's a pics of where it is if that helps.

Cheers.

Webbie,

In your photo you've highlighted the fuel pump speed resistor.

The diagnostic port (or plug) is on the extreme left. It's the light grey box beside the plenum.

 

[webbie]

That's what they were asking about in the start of the thread. Well, that's what hiluxmad was refering to when he replied it was under the bonnet.

But anyway, here's a pic of the check connector so we dont get confused any more

 

[The Witzl]

sorry - i gots confused with people

 

[sideshow]

there is 2 diagnostic ports

one next to engine which is mainly for gettin codes

i also have fitted the one under the dash this way i can connect my snap on scanner and read live data from it as i drive

That's what i told them too..
