wiring

[sark.inc]

dose anyone have any pics or along the lines of what wires mean what that connect to ECU and car?


last step and i can't find anything ;_;

[neo]

it all depends... unless your a jedi .

Make, Model, Year, Engine, bodyshape etc?

how the **** did i forget that

AE101r 1996 corolla, built here in NZ. >_<

Engine is a 4age ST transplant, everything else seems to work bar this one connector causing problems.

If you specify what exactly not working, we could give you useful (maybe?) advise.

[sark.inc]

i guess this might help

the two black ones, also is the gray one needed?

Jesus resolution..
Anyway, the black plugs are the body loom plugs. The gray one looks like ECU plug but I can't really tell.

The NZ New AE101 will not have these identical to AE101 Levin/Trueno. You will need to match wires individually.
Judging from pic I can say that your temp gauge, engine light, tacho, oil light etc. does not work?

EDIT: I just examined the colours on the two black plugs and it looks like most match if one would be plugged into another. You might need to move some of the wires...

As for the grey plug can you trace it where it is coming from? Is it coming from engine loom or car body?

[sark.inc]

yeah some seem to match, about half of the plug matches but the other half has different colors and the fuel power line goes no where??!?!?!?

i have tacho so i assume that's on the half that matchs. >_<

in total i had 4 plugs coming from engine bay, two went to ECU other one goes to body loom (in pic) and other one i have no idea where that goes :S?

am i right in assuming the AC switch wires go through this? if so i assume that would be 4 wires i do not need to wire in right?

[sergei]

some AC wires are going through there.
You will need to get a repair manual from library/repco and cross reference wire colour with what you have in the loom. The colours should be more or less consistent.

Did your car came with A/C at all? If not, it would probably have whole load of wires missing. As for the second plug it is also for body loom as far as I can tell, as AE101 20V has two of the plugs like the black one. What you would find is that you will have to join the 20V two plugs into 1 black that you have for your car. Some of the wires will be discarded.

worskhop manual doesn't really tell you a whole lot about the body connectors. trust me i spent ages looking at them. lol

we are doing this atm on my car to match the BT to ae101. just tracking down the wire we need from the sensors in the engine bay and following them to the body connector. then testing this output on all the different wires on the back of the dash and see which ones we get to work.

turnos out there is only a very small amount of wires that you need to get it working. unless you want AC to work?

[sergei]

Work shop manuals tell you great deal about wiring.
Yes, it will not tell you specific connectors, but generally colour and where the wire going and how it is connected (and what else is connected to it) is very useful. It is very difficult to go around with multimeter and test every single wire, especially when it splits.

[touge_ae101]

i agree i'm doing it at the moment! a lot of work looking through all the diagrams to get the info you need though.

there hasn't got that many wires needed to get the dash going though. and the majority of the body connector wires work the AC.
presuming you're not worried about getting the AC working?

[sark.inc]

i have no AC so don't care for the AC wires.

at the moment, oil pressure, fuel level, rpm all seem to work fine.

i would have thought most signal things go through ECU then to dash(e.g temp sensor, oil pressure etc.), not through body loom? am i correct here?

how ever it seems the rpm counter goes through this body loom to rpm counter.

[touge_ae101]

well then you get to cut half of them out there has got a lot of extra i'm just going to bin.

not sure if it is the same but on my blacktop from memory, oil pressure is a ?white? wire that comes through the engine loom and goes to those big two connectors to dash.
and the alternator (battery) is ?red with blue trace?. i'm pretty sure of this. thats as far as my 20mins allowed me the other night.

if you do manage to trace the wires from the back of the dash would it be possible to post them up here please?could save me a couple of hours next weekend.

[sark.inc]

i can't god damn well figure it out, if i put power to the pump and turn it on, it fires up but will not rev just barely idle, all the gauges seem to be working right.

what am i missing?!?!?

the fuel pump simply won't turn on and the battery light stays on.

The more and more i look at it, the more and more i think it must have something to do with the fuse box part :\

i am about ready to pay someone else to do this.

[sark.inc]

well i am only getting 0.2 volts off relay at fuse box under bonnet, i guess this might be the cause?

[sark.inc]

the fuel pump in these is either on or off right?

so i could just hook up a switch and run the fuel pump by it self?

also that relay under head deck, is that where the power comes from for fuel pump?

also does this relay feed power to ECU?

[touge_ae101]

nah power for ecu should come through loom from the fusebox. should have a B1 and B+ wire that should come through the loom. thats how it is on BT anyway.

yeah i'm pretty sure that relay runs fuel. should be already switched by the ignition/ecu so no need to add an extra switch.

have you been on bill sherwoods page?he has awseom documents on the Silvertop wiring system.

i could not find them :S?!?!

does the ECU at all control the fuel pump?

Have a look here as well - might be of some help.
