installing tach in 93 pickup
 

Could someone please guide me through installing a tachometer in a 93 nissan hardbody pickup. Thanks in advance. The tach is a Cyberdyne with wires for dimmer, sender, 12v, and ground.

dimmer wire goes to lights, sender wire goes to ignition coil , 12v wire goes 12v positive and ground wire goes to chassis ground.
