why was 89 a weird year for the MK3... just wondering...
- Thread starter ilovemysupra
- Start date
There was a thread about this a long time ago. Toyota just kinda slapped 89s together with whatever they had left, some cars had random pre-89 parts.
89's have been known to have either the square or round motor mounts.
89's have a lot of electrical variations not always coverd sepcificaly in diagrams.
89's can have either connector plastic type yellow or grey.
89's can even have different connector shapes.
like you said a lot of mixing & matching of parts.

Starting in 01/89 the subframe/mounts changed to the newer style.
I've never seen an 89 with yellow connectors, people have said over and over that they exist, but I don't believe it.
From all the 89's I've seen and/or worked on, they were all exactly as the wiring diagram showed.
I think people get confused when they see a production date of like 09/89 and then it has the wiring for 1990, when it is of course a 1990 model year car.
If anyone has a 1989 Supra with yellow connectors on the ECU, post a picture of the ECU showing the part number on it, as well as the data tag. I doubt a single person can provide this.
Yes the 89 model year was different than the pre-89 and the newer cars and is usually best treated as it's own year, but there is actually very little variation between different 89 cars.

yes we do..!
I have a November of 88 production 89 and it has a gray ECU plug..
i saw another 89 with a build date of august and it had a gray plug ...

mine is a sept build date, all the chassis plugs r grey, i was lookin for the stock NA ecu that came in my car but couldnt find it...
look behind the glove box..
you can get away with bending back the plastic behind the glove box and shining a flashlight in there to check the plugs..

On my old grey 89, I was able to use an engine and yellow plug harness out of an 88. It plugged in with no issues.
I think they had the best steering wheel but I'm thankful for my 91. There's no variations to worry about.
