hey.
i have a 90 240sx thats a manual. i am putting in a 93 trans. i noticed that on the 90 it has a OD gear switch, but on the 93 it has a 4th gear switch and an OD gear switch.. well my car does not have a harness connector for the 4th gear switch.. i was wondering weather or not that the trans would be ok, or would i not have a speedo in 4th gear?

thanks.

 

your putting a manual 93 trans in a manual 90 body? 90 and 93 trans are the same but if you really want to fix that problem use the 90 harness and sensors

 

the only sensor that you need down there is the speed sensor. keep the automatic computer and everything will work just fine.
