93 LX father son project

[ZAM93LX]

I'm not sure where to start this post so I'll just start and see where we get. When I was 21 I bought a 93 LX 2.3 car and a 91 LX 5.0 donor car that was very rotted out. My dad and I started doing the 5.0 swap to the 2.3 car and in the process my dad got sick with cancer and passed away. I let the car sit for around 12 years basically untouched and decided this year I was going to get back on it and finish what we started.

The car is a bit of a basket case but its fairly close to running. The engine is in, transmission is in, rear end is in it and the engine harness is 80% connected. I came to this forum to get help with the last 20 percent of the engine harness wiring and routing of the vacuum hoses. I'm trying to figure out exactly what I need and what I dont need, mainly just some connector ID and sorting out what's from the 4 cylinder car that I can remove from the harness. Thats about it, I won't drag this post on but I wanted to make my introduction, I have a feeling you'll be seeing a fair bit of me asking questions around here so thanks in advance for any help you guys can give!

I attached a few pictures of the car just for reference of what we're working with here.

Nightmare seems accurate, it feels like putting a puzzle together with all square pieces sometimes haha
I think you're right, I've been reading some threads and their seems to be some very knowledge people on here.

Well how bout a brief on what wiring was swapped 'cause most of it will now mix and match.
Do you still have the parts car?

I swapped the engine harness, dash and dash harness and ECU from the 91 5.0 car
The body harness is still the original 93 2.3 car.
I have most of it sorted theirs just 4 or 5 connectors I'm not sure about.
I dont have the parts car anymore unfortunately, I needed the cash and sold it off as a roller several years ago.
I made a progress thread in the 5.0 tech talk section with the same name that goes over basically what all has been done to the car up to this point.

Progress Thread Thread '93 LX father son project'

Oct 26, 2025

I made a post in the welcome wagon about this but I'm going to start a progress thread here to keep all of the updates in one place.

Long story short when I was 21 I bought a 93 2.3 LX car and a 91 5.0 LX car, the 91 car was super rotted so my dad and I started a 5.0 swap, in the process of that my dad got sick with cancer and passed away. I let the car sit untouched for around 12 years and decided this year was the year I finish it. Ive been making some progress on it but I have some questions surrounding routing the vacuum lines and a few electrical connectors on the car I cant find...

Awesome father-son project! Pretty cool that you’re finishing what you and your dad started. Planning to get a cowl hood?

Thanks! Its been a long time coming, I'm just going to run the factory hood, my goal right now is just to get the car running and go from there

 

[RockstarMach1]

Good luck with the build man! IMO Cowl hood is more appropriate on a supercharged setup

Thank you, I appreciate it! I'm not a huge cowl hood guy but I could probably be talked into a supercharger

 

[Noobz347]

They have 'little' cowl hoods too.

I mean as long as it clears the supercharger a little one will do fine haha

I think you know but the dash harness in the 93 car will not directly connect to the 91 ecu harness over by the brake booster. If you have the wiring diagrams for both cars you can make it work. If you need the wiring diagram for the 93 let me know.

As far as what? I have the two bigger 8 pin connectors plugged in by the brake booster

They are pinned differently. Good thread on this here:

I knew about the fuel pump relay, I wired in a fuel pump relay in the hatch to correct that issue
I bought the LMR headlight harness and stator plug to wire in the 2g alternator so I have that figured out but I'm unsure about pin locations on the body harness
I know theirs two circle 8 pin connectors behind the driver strut tower by the brake booster a grey one and a black one, they plug into each other but I'll have to look at the pin locations and see what's different between them, if I have to move some pins around thats not a huge deal.
The dash is out of the 91 5.0 car too so I'm not sure how much of the body harness of the 93 4 cylinder car comes through the firewall on the left side.

I'm going to copy your last post from this thread over to your [Progress Thread] and close this down.
