So keep the 1zz harness and then make adapters the ECU?
2zz swapping my prizm hopefully any and all info is very appreciated
SO, I have an 02 prizm , 1zzfe , burning oil like crazy and started knocking I need a new engine and I’ve wanted to 2z swap it for a while now , I’m going to eventually so I don’t see the point in buying another 1z just to put a 2z in later , so here’s where I’m at for requirements
2zzge from a 02 celica gts (cable throttle)
Celica gts ECU 02
engine harness from a 02 celica
1zz exhaust header
(i want to c60 swap it as well but that’s not in the budget right now so im sticking with the c59)
I know there’s issues with wiring the engine into my car but I have no idea WHAT those are , I’ve read that I can use a 02 4spd auto corolla harness with extra wires for pressure sensors and vvl but I don’t know what that means so pls help

So if I understand it correctly you’re making the 2z ECU compatible with the 1z harness? And then everything from the 1z harness will plug into the 2z?
So my dad thinks that wiring the ECU like that is a terrible idea is there any particular reason not to use the 2z engine harness? That way it all plugs into the engine and ecu no extra wires or anything? I’d rather keep the 1z harness that way the car functions the same and I don’t have to make a hybrid harnessHey, I've done that exact swap. A 03 Matrix ECU or 00-01 Celica ECU will be better. For wiring, don't bother swapping out the harness. It's best to leave it completely stock and build an adapter. I have all the wiring diagrams you need. I have been working on a full DIY guide on the entire swap, I'll polish it off and post it soon.
New to the site and am struggling to find where I can pm you lolUsing the 2zz harness, you would have to adapt a whole bunch of plugs to get the engine harness to communicate with the body harness. You would also have to construct your own fuse and relay panel or do a ton of custom wiring to get it functional with the Prizm fuse box.
If you leave the 1zz wiring harness in place, you only have to adapt 4 plugs to connect the 2zz ECU to the existing harness. The existing 1zz wiring harness plugs into the 2zz engine itself just fine, almost every single plug is the same between the engines. If you want to avoid wiring all together, there's a company called Panic Made that sells the ECU and harness adapter for $1,400. If you PM me, I might be able to make the adapter you need for a lot less than that.
He’s probably going to end up helping me solder because I’ve never done it ,actually I’ve never done any of this , I did the clutch a few months ago so that’s where I’m at for experience LOL, BUT on a happier noteWhy not have your dad help wire it up then?
Engine is on the way it’ll be here like the 18/19th
The Ecu aswell it’s a 03 matrix 89661-01040
Also @1998Prizm you had mentioned getting male ecu plugs from a junkyard , is that my only option? I did some digging and couldn’t really find anything perhaps I’m not looking under the right stones?
Well i started tearing into the car today , and I did not realize just how many wires and hoses and THINGS there are and I just don’t know what they are and I labeled some things to kinda remember where they go but after comparing the intake manifold on the 2zz to the 1zz and seeing that connections are in different spots I’ve changed tactics to unplug as many things as possible and I feel like this is a terrible idea but I want to get the 2z in and then i don’t think it will be too hard to figure out hoses and plugs
Soooo the 2z that I got , doesn’t have a power steering pump on it so I guess I’m adding that to the list , and yeah I’m hoping to keep my A/C I had my fingers crossed the compressor was just gonna bolt on to the new engine , I’m trying to not crack a line but we shall seeOnce you get the 1zz out, and the 2zz in, you can lay the wiring harness on top of the engine in roughly the right spot, and everything will line up just fine. It doesn't look like it will, but it does. When you get to the point where you need to put the vacuum lines on, I'll send you detailed pictures of my setup.
One thing you have to piece together is the power steering pump. For that, set the 1zz and 2zz PS pumps next to each other on a workbench and look at the fittings. Theres a big bolt on both pumps and if you unbolt both, the fittings for each pump will come off and you'll be able to put the 1zz power steering pump fitting on the 2zz pump. That way you'll be able to retain all the power steering stuff without any custom hoses.
What's your AC setup like? Do you plan on keeping the AC?
OKAY so finally got my A/C compressor off and I’m getting ready to take the bell housing bolts off and I’m looking at them I totally forgot about it from when I did my clutch , there’s one bolt at the bottom blocked by the crossmember , do I take all the other bolts out then loosen it as much as I can and wiggle the motor out or do I HAVE to drop the crossmember?
I really did not want to do that because I didn’t want to pull my CVs and 3 other mounts sighIMO it's best to pull the engine and transmission together, then pull the bell housing bolts once the engine is out of the engine bay.
if I can do it the way I’m talking about then that’s how ima try, that and then my dad would be right LOL
Okay the next piece in my lovely swap puzzle (besides the elbow grease of swapping engines,which btw the 1z is out so first ever engine removal is a success and I didn’t break Jack !$&@) IS to get male ECU plugs , i don’t recall if I had shared that I got an ECU , but it’s a 03 matrix 89661-01040 , ANYWAY will any plugs from any M/T matrix ecu work? Or do they HAVE to be from an XRS because if I can go to a junk yard and pull some plugs from a soccer mom mobile then awesome! Just wondering thanks
Okay so it’s been a while here a little bit of an update.
Come to find out , my 1z flywheel doesn’t fit on the 2z so cool
Parts on the way
2zz flywheel
2z power steering pump
Once those get here I can start putting the engine in the car UNLESS there’s something else I need to get , I’ve seen something about an engine mount bracket?
anyways today I got male plugs for the matrix ecu , BUT they’re from a base vibe manual , I was in kind of a hurry so just unplugged them and cut the plugs with about an inch of wire so I’m not sure if the type of ECU they came from mattered but they fit my ecu so idrc. Now that I’m ready to pull the prizm ecu out and start working on soldering n such I gave the prizm ecu location a quick Google search :| ifykyk so I have that to work on that’s about it for now let me know if I’m missing anything thank you for everyone’s help and input so far!

Okay a little bit of an update
The engine is in the car and it has been in the car for a while now, I’ve only got a few things left to do
Hook up power steering hoses to the pump (old pump is still dangling in the bay LOL)
Finish my ECU adapter , they make heat shrink solder joints so I’m using those I just got new plugs with MUCH longer pigtails today
Custom exhaust header ( more in this in a sec)
I having troubles with my passenger side mount, the prizm bridge doesn’t fit and the matrix bridge is too short , solution is to cut one stud off the prizm bridge, and re-weld it closer to the other stud , similar to the matrix bridge width I think I know someone who can do this
But for my exhaust , I think I’m gonna go with SC Chinchillas idea , mrS header , with a custom 2-1 down pipe or whatever it’s called, BUT that’s super restrictive isn’t it? Or was it just the stock 1zz mid pipe that was restrictive, I’m gonna take my cat out too so that might help? Opinions are appreciated
I have to put my intake back in but before that I have to put my new slave cylinder in because i broke my old one smh
After all that it’s just small stuff and working out any kinks I run into OH and I have to run those jumper wires for Lift and the pressure sensors too

Here me out, hood exit.
Well it’s been quite a while since i asked why questions and this should be my last hopefully , are there any wires I need to run in the ECU adapter for the OBD port besides the ones on the wiring diagrams that 1998Prizm linked me to? There was 4 OBD wires on the matrix side and 2 on my prizms side , I have the two prizm wires connected but there’s still two other matrix ones???
Okay so comparing my diagrams you gave me between the corolla and matrix ECM , I’ve got four OBD pinsIirc, you have to run them straight to the OBD port, but they're not 100% necessary to run the car.
What are the extra Matrix wires called? And did I send you the OBD diagram? If I didn't, I'll send it over.
On the corolla there is
TE1
SIL
On the matrix there is
SIL
WFSE
TC
I have SIL connected but am wondering about the remaining 3
You mentioned “Iirc” I’m not sure what that is?
And if you could send the OBD diagram/s that would be fantastic![/QUOTE]
I got the car all filled with fluids yesterday and after some trial and error she started up she was running rough but I think there’s just air in the fuel line still. I didn’t run it very long because open header in small garage but very very exciting.
OKAY so turns out the idling problem was a ground LOLOL CHECK YOUR GROUNDS PEOPLE but now all that’s left is too relocate my battery (any advice on that is appreciated) and I need an exhaust from the down pipe down
OH and I need the obd wires , I’m getting an engine light which is expected because the down stream O2 sensor is just dangling but I want to double check itOKAY so turns out the idling problem was a ground LOLOL CHECK YOUR GROUNDS PEOPLE but now all that’s left is too relocate my battery (any advice on that is appreciated) and I need an exhaust from the down pipe down
