120 speedo swap (Page 1/1)

I have a 1988 4cyl notchie. I've installed the center console gauges( batt and oil pressure) those were easy plug in and go.
can i just remove the 85 mph speedo cluster and just plug in the 120 cluster or is there modifications required?

Plug and play

Are your tach and fuel/tach gages backlit?

You can't run two oil pressure gauges in parallel, (the resistance is too low and inaccurate) so until you get that 120 tach in there you need to cut the wire to the build in oil pressure gauge.
