MX83 2jzge wiring questions

[hybrid_turbo]

hey guys, most of the way through my 2jzge engine conversion in to my mx83. got everything bolted in and sorted. its just the wiring.
im a noob when it comes to that unless its a stereo, im also colour blind so this should be fun. i want to do it myself though, never learn if
you dont try hey.

anyway, still going through the engine loom to body plugs under the dash but atm im confused on where or what to do with the two plugs that come off
the engine loom and go to the body loom near the fuse box (on the jza80).
also not sure what to do with the alternator plugs from the old 7m?

i also dont know what to do about the fuel pump wiring, had a few looks around but seen a few posts where some people have done something and then
been told its dodgy and i would rather do it the right way.

any help would be greatly appreciated.

some pics of the plugs.



and some pics of the engine bay.

the 2j plugs in enigne bay need to be lengthened or moved inside to join to wires behind glovebox

the alternator wires need to be lengthened to the other side
fuel pump on cressidas i normally runa tachometric relay to trigger the original circuit opening relay
and remember to bypass the fuel pump resistor too
if its auto u need a start relay fitted cause cressdias had fat wires to inhibitor but yr 2j will probably have thin wires
u will probably need a tacho booster to get tacho working

sit down and probe the body plug wires then join the matching ones
not hard should take u a full day if u know what your doing

[hybrid_turbo]

had a feeling that was going to be the case, will work on that this week then.

with the alternator plug, do i use the mx83 wiring with the jza80 plug ? atm i have the alternator plugged in but its the plug and wiring from the engine loom for the 2jz.
looks like i'll be going to jaycar for the tachometric relay stuff then.
where abouts do i find the fuel pump resistor? relay should be easy enough, its just so the fuel pump shuts of if the engine cuts out, like in an accident?

good thing its manual, using a ma70 w58 in it, so i wont need that.

[dumbass]

u need to use whatever plug suits the 2j alternator
and probe the wires and see which one goes to what
jaycar don't sell tachometric relays
I sell ones to suit toyota circuit opening relays or just goto local wreckers and get one of an old commodore

Did not need a tacho booster when I did mine and I used the proper Fuel Pump Control to run the fuel pump

hey guys done most of it now but having some issues. have it cranking and trying to start but i dont have injector pulse or spark.
im not sure whats going on, just asking to make sure what wires i need to connect for this.

i have fuel running all the time atm just to get it running while i get a tachometric relay for the fuel pump.

Assuming ge will be simerlar you will need to add power near your ecu to power up injectors and coil. remember that they have constant 12v and are fired by the ecu earthing.

[dumbass]

behind the glovebox there is a fat black/yellow wire
this is original power for 7m injecotrs and coil so use that and connect it to
the two black/orange wires
pretty sure there is 2 and some guys forget to hook up both
and then only half the shit works
but as a good test
check for ign power on each coil and on each injector that way u will be 100% sure

[hybrid_turbo]

We got it running in the end double checked and tripple checked
Everything and everything was fine but still no pulse or spark. After hours
Trying to figure out what was wrong we raped my supra for its ecu
Just to rule it out as the cause... plugged it in and it fired straight up.

Runs smooth as bloody cheering. Not happy about it being the ecu though


Cheers for the help guys
