Ls swap question?
Hey guys in looking to doing a Ls swap in my 84 berlinetta. How do I get the tach to work? I have the space ship dash?

Re: Ls swap question?
the tach signal on the LSx swaps comes from the pcm (red connector, pin 10). since the ls setup puts out a 4 cyl signal, you will need to get it reprogrammed to correspond to the tach in your car (6 or 8 cyl)
