There are so many variations I have wires that do not match to a lot of the car. It looks like a dogs breakfast in the cockpit. There is a complete harness just laying there not connected to anything. One of the previous owners of the vehicle decided to use electrical "Tag blocks" to install the sound system. Left wires exposed and it just looks terrible. There was a turbo timer installed as well which I have chopped out, however I want to replace it with a new Apexi turbo timer that I have, however the old one never worked so I do not know if this ever worked. I just want to wire it up properly. There is a thick blue with a red stripe cable that has been completely cut from the connector block and soldered together.
There is no know JDM wiring diagrams for specific years available online. The best we have to work with is the 1991 USDM diagram that covers 89-93 JDM cars. However not all of it is the same and you can only find this out by looking at the diagram and the wiring and deciding what matches and what does not. Unfortunately this diagram is in black and white but does have colour codes for wires.

Yeah, I spent two days going over that with a fine tooth comb, there are still a couple of things that are in place that I do not know where they go. Like for argument sake installing a new head unit as well as speakers through out the car. Where are all the contact points. This car has been butchered unfortunately and I want to clean it up.
Thanks GDII, as always really appreciate your guys help and advice
For the aftermarket head unit and speakers, you are best to completely disregard the factory system and install new power, ground and speaker wires as a stand alone system. The factory wiring and amps is really odd and with some tiny wires there is no point trying to reuse them.
As far as I know on my car the power for the head unit comes from the amp in behind the passenger door then weak signals sent back from the head unit to the amps then amplified signals are sent to the speakers and the woofer has it's own amp. Just messy.
The other wires, hard to figure out without seeing the car. I don't know much about the wiring under the dashboard, I've never ventured that far before.

Good idea, was going down that route. You just gave me confirmation. Also want to remove all old wires through to the doors and other wires as I beleive there might be something more sinister going on as my central locking is not working and suspect a couple of broken wires.
Will get there in the end Only taken me 7 years so far
I have the same issue. The doors lock but do not unlock so I think there are a number of wires broken. It is only on the drivers side though. I will trace all these wires and actually replace pin and wire for each. I think JCAR is about to become my new best friend
