Hi all just have questions about manual converting my e36. 1. Can I use a pedal box out of another factory manual model like a 318i? 2. I’m not the best at wiring so how difficult is setting up the ecu or could I find a manual ecu and just plug it in? 3. Is there any fabrication involved in making it fit? Or does it all bolt up fairly easy with the right parts? Any other advice would be welcome just trying to figure out if I do the swap or hold out till I can afford a factory manual Cheers.
