tach

[spence]

can any body tell me how to hook up an aftermarket tach in my 91 cutlass supreme

Um....why? You plan on doing a lot of racing?

You usually need to install a sending unit of some sort when installing an aftermarket tach (or any aftermarket gauge). It should come with instructions and the sending unit.

i wouldnt spend the money on a tach when theres already one in the car..i might not look that great but it still works the same....i would maybe only buy a shift light if i wanted one and was doing a lot of racing

my cutlass only has the basic digital gauges not the fancy ones so could I hook an after market one up to the factory wiring

No..you could not hook up an aftermarket tach to the factory wiring.

A shift light would also be pointless...even if you do a lot of racing, unless you have a manual transmission.

You can get an analog cluster from a junk-yard and swap that with your digital cluster. Just be sure to find one that has milage close to yours.
