I am wondering about buying a all new engine wiring harness for my '93 SC400, but need a part number, as I have had no luck finding it yet. I know Toyota still makes them for the MKIII supra, so I don't know why they wouldn't for the SC4...

 

you should look into a used one. the new ones are very very expensive. (1000+)

 

I know that, but any used one is going to have the exact same issues as the current 2 I have, super brittle rubber and plastics, broken connectors, etc.

 

zip ties are your friend.....lol
thats the problem i ran into also..
new ones are very exspensive...lmk if you find a lower price hook up
