my friend blew his motor on his 90 DA and i had a 93 ls motor sitting around so im gonna swap it over. i got his motor out and started pluggin up the wiring but on his 90 DA motor there is a plug on the back of the block that is yellow w/green stripe and the other is black. On my 93 DA motor that sensor is not even there. Does anyone know where this would go. I think its the engine coolant temp sensor but i have no idea where it is on the 93. Can anyone help???
