R33 Auto To Manual (rb25det)...can I Use The Auto Speed Sensor?

[nsta]

Hey guys, i done the conversion from auto to manual in my r33, with a 25t box, and we plugged the manual speed sender into the box thinking it should be sweet....

i took it for a drive, and the speed is showing around roughly half of what it should, ie when im doing 100, speedo shows me doing 50km. Was i suppose to just plug in the auto speed sensor to the manual box?will that fix my problem?, i dont need an r33 speedo cluster do i?

this is affecting not only my speedo, but my steering as well!!!

bump, been doing heaps of search and research on this forum, and it looks as though the auto speedo sender doesnt work on the manuals 25t box, is smaller in length too, as i pulled it out. How is the speedo suppose to be wired up, im thnking i may have done it wrong.
