supra mkiv 1jzgte swap help needed

[leeti]

i have matched up what i think from your wiki and i have these left that im not sure what to match them to.

12v alt to charge
park neutral detection
m-rel which i have connected to a live constant
tb dash ignition power
starter signal to dash
e1 dash ground
gnd for exhaust temp
and
power to auto trans
the others i think are right the car goes to start but cuts straight out refusses to idle.
and i have no life on the auto trans switches.

also on 1 of the plugs theres a black/yellow wire which is thicker than most of the other wires.
cheers lee

If you also list the plug and pin numbers of the wires you haven't been able to match that would be helpful for us to help you


Read this page in regards to the M-REL engine ecu pin.
wilbo666 / M-REL - 6 Wire Idle Speed Control Valve (ISCV) Wiring



Pin 23 on the below plug (JZA80 side) needs to be connected to IJ1 Pin 10 to power the auto trans shifter (so you get indication on the dash etc) and it also powers the speed sensor.

thanks for that i connect the speed sensor power and auto trans power ign pin10 ij1 to pin23 on the supra orange plug but found i had no batt light or engine light. but i did have auto trans power. so alternativly i changed pin 23 to go to black/yellow on 1j2 12v to alt to charge and put the
pin 10 ij1 to black/orange of ij2 and black/orange of the ik2 i had auto trans power and batt/ engine light come on and go off when its started. would this work ok.
i am now stuck with the fuel pump and also the tachometer which i need to do the mod.
and these are the wires i have remaining?
white/red ij2 pin2
brown/yellow ij2 pin9
black/white ij1 pin6
ik1 green/orange pin3
ik1 black/yellow pin14
1j1 red/green pin14
and the white plug yellow pin12,green/blue pin7, green pin9,black pin10.
these are the fuel wires i have
ij1 fp diag pin1 green wire
ij1 di fuel pump control signal pink wire pin8
ij1 fpc power fuel pump control signal pin14

and i left the thick black/red ij pin12 direct to battery as i still

and on the supra
pin4 fuel pump control purple/white
pin8 fuel pump diagnostic blue/red
pin12 fuel pump ecu green wire.
all on supra gray plug.
i connected them but heard no prime from fuel pump.
or is it cuz got to earth it some where or missing something.

thanks loads wilbro cheers lee

i just had it running for a while by running the pump straight to the batt on and off because it will cut out if i leave it on constant.
oh and now my temp gauge does work now the car run for longer but i havent sourced a middle pipe exhaust for the car yet.

To be honest it is pretty hard to follow what you are talking about there - it is very confusing the way you have worded what you have done

and these are the wires i have remaining?
white/red ij2 pin2
brown/yellow ij2 pin9
black/white ij1 pin6
ik1 green/orange pin3
ik1 black/yellow pin14
1j1 red/green pin14

I suggest that you also list the function of the pin / wire, such as follows...it does make it easier
*IJ2, Pin 2, White/Red, ?
*IJ2, Pin 9, Brown/Yellow, OD, Overdrive Disable
*IJ1, Pin 6, Black/White, NSW, Park/Neutral Detection
*IK1, Pin 3, Green/Orange,VF Diag Connector, Used for 'Voltage Feedback'
*IK1, Pin14, Black/Yellow <THIS WIRE COLOUR DOESN'T MATCH YOUR PICTURE>...


And matching...
*IJ2, Pin 9, Brown/Yellow, OD, Overdrive Disable --> JZA80 90980-11562 plug, Pin 11, OD1

*IJ1, Pin 6, Black/White, NSW, Park/Neutral Detection --> JZA80 90980-11469 plug, Pin 7, NSW

Note: This is the pin that should be sending power via the auto trans park/neutral switch to the fuse box mounted starter relay to allow the engine to be started... the fact that you can start the engine at the moment without this connected properly means you have something in the wiring bypassed or wired incorrectly

*IK1, Pin 3, Green/Orange,VF Diag Connector, Used for 'Voltage Feedback' --> JZA80 90980-11469 plug, Pin 13, VF1

these are the fuel wires i have
ij1 fp diag pin1 green wire
ij1 di fuel pump control signal pink wire pin8
ij1 fpc power fuel pump control signal pin14

Matching...
IJ1, Pin 1, Green, FP, Diag Connector Fuel Pump Connection --> JZA80 90980-11469 Plug, Pin 8
IJ1, Pin 8, Pink, DI, Fuel Pump Control ECU Diag --> JZA80 90980-11469 Plug, Pin 12
IJ1, Pin 14, ?, FPC, Fuel Pump Control ECU Signal --> JZA80 90980-11469 Plug, Pin 4

and i left the thick black/red ij pin12 direct to battery as i still

I believe that this wire is the output to the fuel pump ecu in the JZZ30. I believe that the JZA80 fuel pump ecu power feed takes a different route so you should be able to leave this disconnected I believe.

sorry for the crap write up wilbro. i did do it propley but my net went off when i was posting it lol well better than what i ended up doing lol.
1 did connect them 3 wires but nothing seemed to happen ill try again anyway.
the black/white wire there are 2 one on ij1 pin9 and 1 on 1j2 pin6 so i put the nsw off the ij1 pin9 to the supra nsw?
will the car idle ruff with just the downpipe on as im next to find a centre pipe.
thanks lee

i have put the exhaust on and the car sounds like its running on so many pots or shall i say lumpy and its very smokey. any idea have i got something wrong i wounder?
