i have a 96 dx hatchback, with a 00 si motor and si ecu and harness, the car was a 4speed and now a manel , so the computer is making the car think its in park from the stock cluster....so the mph gauge dont do ****..is a si cluster all i need for that damn thing to move

 

Using an Si cluster is not a solution to your problem. Did you use an OBD2 to OBD2.5 conversion harness or did you just use the Si harness and rewire the odd plug? It sounds like a wiring problem to me.

 

if you did everything correctly then the lights on the prnd shouldn't even light up. my friend has a auto ex cluster in his 5 speed 98 civic and everything works just the way it should.

 

Doesnt sound like a cluster problem. I wll garantee the problem is because you are using the SI harness. I dont think the SI harness will work in the hatchback,

 

I second that. You should have used the 96-98 EX harness or modified the stock DX one.
