You could check the resistance and continuity with a multimeter.
But honestly unwrapping / cleaning the OE harness take a lot of time and is very messy...
If budget is a huge constrain, fixing what is wrong with it is probably the best way, but god I'd do anything to avoid messing with that !

I got all the OEM connectors from Ballenger:

The other option is china (it's incredible what you can find there )

In my case I also use a combinaison of motorsport and military connectors, wires and heat shrink (Deutsch DTM, MIL-C-38999, M22759/32 and DR-25)
But that's not for everybody.

Be careful, money goes fast with this kind of stuff. (Trust me I know...)
You have to consider the hardware (wires, connectors, etc...) but also the tooling.

At a bare minimum I would recommend the Hozan P-706 crimper.
I's a must for Japanese connectors.

But I have to wait for another year to collect the proper money for a good aftermarket ECU and program it.

MS clone like EFIgnition 46 are not super expensive.

The ECUmaster EMU Classic is also a pretty good value for the money considering it has a internal wideband controller.

If you are not using the OEM ECU I would highly recommend to modernize the wiring (sequential ignition and injection is a must)
On my friend's carina I have used a set of 1ZZ coil and Sard 300cc injectors combined with a MS (heavily modded DIYPNP)
