I am currently building a Volvo 242 with a procharged LS1 engine in it.
The transmission is a T56. The complete engine package comes from a Camaro SS 1999. Some pics can be found at http://www.hocky.se.

Got one problem with the speedometer. I have retrofitted one electric VDO speedometer from a newer Volvo car and is trying to get this to work.
Problem is that it wont move...not at all :(

Anyone done any similar?
What type of signal is generated from the ECU?
Is this the same type of signal that comes from the transmission?

Thanx!
