[Falken-18c]

What ecactly do i need to make my 93 ej22t to work in my 92 na body do all i need is to plug ecu and a harness which harness Pics Would be GREATFUL THANKS. I was just hoping i didnt need the all there thousands of wires lol

well if you don't swap the front chassis harness, you will atleast need the N/A engine harness installed on the 22t engine, and you will have to move several pins on the ecu plugs and wire in all the boost sensors.

That is ofcourse if you wish to keep the chassis harness on the n/a

Or just swap out the whole front harness with a turbo harness... there's not much to taking the dashboard out at all.

yea i took out the dash board out of the ss but i just smash it apart lol but soo ill need all those wires probly be easyer to put in the whole 22t harness idk what id have to do to move the sevral pins on the ecu plug and wire on all boost sensors is there a thread that i can see

[Falken-18c]

could i just cut my ecu plug off the 22t harness and wire it up

[cj91legss]

it's much much less of a hassle to just swap the harnesses

[Falken-18c]

yea ill probly just do that but theres 2 plugs i cant seem to unplug one with 2 bolts in it and then another yellow on with a green thing the u push in but the wont pull a part so i might just snip them and re wire them up in the car that shouldnt be a problem if i sauder them together should it

[Falken-18c]

oh yea can i pull all them wire through the out side and not the inside if i tape them up

[cj91legss]

uh, i think it's best to pull from the inside, you'll have to remove your hvac stuff as well.

yea thats what i was thinking but lil wires still pluged in under intake manifold i cant seem to get at maybe ill have to remove it to get em all thanks

[Falken-18c]

when i went to un bolt the black plastic for the ac and heater it was holding on aluminum pipes that i dont even think u can get at i just smashed my ss one apart lol gunna have to be more carefull with my other car lol

Keep your n/a engine harness and just relocate the coolant temp sensors to the driver's side of the harness and use it on the turbo motor. Other than that, all you need to add are the turbo specific sensor wiring, wastegate solenoid (boost control), MAP sensor, & pressure exchange solenoid.

You will also need to swap the positive leads for the crank & cam sensors.
