Fault code 33 issue 95wrx
 

Been fixing up a 95 wrx wagon, I purchased it as is thru a m8 on impulse. So never had a chance to talk to the person responsible for my nightmare.

However its had an engine upgrade along with ecu & wiring loom. Which would all be fine if they had used the gearbox to match the newer power plant! Here's the problem. Original gearbox has the manual speed cable where the newer V4 has the electronic equivalent. So after replacing the cable with no joy i came to the conclusion the Ecu needs that signal..
Anyone know a way to trick the ecu into thinking there is no issue? Or like i read above can the Speedo drives be swapped from mechanical to an electronic one. Obviously would need to change my dash cluster also to match. .

Fit mechanical speedo drive to later gearbox and carry on as you were.
