Tpi Vss?
Tpi Vss?
I have a 89 RS that I am putting a 90-92 TPI on there.
My car uses a cable driven speedometer, and I heard the TPI needs a VSS to function correctly.
What the hell should or can I do?
Point of Interest.....my car has a plug for a electronic VSS that has never been connected to anything.

Your cable driven speedo has a VSS already it’s on the back of your gauge cluster. You will need to either reprogram the chip because the older VSS has a different pulse rate or buy a conversion box.
