well i ended up spinning a bearing last fall at silver, it does wheelies. it is now back together but not running 100% yet.

Ethan any progress? have you been down to Holland lately?

so i am trying to figure out what wire i need to tap into to get my aftermarket tach to work, i have a jzx90 out of a chaser and can't figure this out, can anyone help me with this?

figured it out the small black with a yellow tracer is power to the cam's and crank sensors. all the injector powers come off the big black with yellow.

i didn't slit the injectors they split in the harness before the plug.

dude what you said makes no sense to me this is my first swap i put it into a toyota pickup and i started with the jzx90 engine harness, and ecu, and just wired power to what it needed to run, i can give you pictures of what i ran power to if you need to.

dude i have been racking my brain for a week about this, Thanks again for the help 92tealsupra!!!! I AM SO DAMN EXCITED shit is starting to get done.

i have no idea i am no kind of 1jzgte god i just bought my first one and have been dealing with this issue for 2 weeks, talk to 92tealsupra he might be able to help a little more.

i figured it out you need to do this read my last post it should start like a champ http://www.supramania.com/forums/showthread.php?123194-i-need-1jz-ecu-wiring-help-GOT-IT!!!!-whoop-whoop&p=1567595#post1567595 THANKS 92TEALSUPRA for the help, when i am done i will stop by you on the way to...

alright this is what i did to fix in case anyone was wondering, i ran power to the far right plug to B+, B+1, BATT, and IGSW, this bypasses the main relay so you don't have to dick around with that. Next i found the gray plug between the ecu and engine that has the 2 bigger wire in the middle of...

if you have a chaser their is 3 gray plugs all together between the ecu, and engine, and right by the ecu their is 2 white plugs one has a plastic cover over it and looks like one big jumper box, if this is the harness you have i might be able to help a bit.

ok so if i have power to the igniter should i have power at the coil without the motor cranking over? so i should check for continuity between the power wire to the igniter and my crank, and both cam sensors too? ---------- Post added at 01:49 PM ---------- Previous post was at 01:47 PM...

alright i found them they are, in a gray plug one goes to the 4 pin plug on the igniter and the other goes to one of the 2 wires on all the injectors correct? still not sparking, correct me if i am wrong the igniter fires when the crank sensor sense's movement, im thinking that i don't have...

alright thanks.

thanks, that's a start

will do, i just need to figure out what of the 2 empty ecu plugs need power and of the other 4 left over plugs coming out of my harness needs power. i have power run to b+, b+1, Batt, and igsw, this is straight power to the ecu with skipping the m-rel. This is what i have come up with, using a...

i don't have anything to plug anything into except for the ecu. thanks for the advice, I just PMed him

thanks

" the only downside to them, is you need alot more wiring work", ok with that said do you know how and what wires have to be hooked up for this bitch to fire, i have found some wiring diagrams and none of them seem to be the right one, i also need the pin outs for this ecu, the jzz30 pin outs...
