W202 5-speed manual conversion -> Speedo signal
 

Hello everybody.

I do have a small challange at my brothers car:
Implant a 1995 C230 Kompressor-engine incl. 5-speed manual tranny into his 1991 190E 2.0 with 4-speed manual.

Keeping the 4-speed is not an option for us.

Did anyone of you do a 5-speed or 6-speed conversion?
If yes, how did you solve the problem with the speedo-signal (W201: speedo cable <-> W202: no port for speedo cable at the tranny.
