[Baby Blue]

model F15XRB,
I currently have the 2 set of multi function digital gauges and want to add the following
volt gauge
temp gauge
tilt gauge
fuel gauge..
can I use the existing sending units for any of these gauges
Thanks.

All but temp gauge , you would have to get the temp sender to operate temp gauge. You can't have 2 trim gauges or fuel gauges to operate on same sender so you would have to disconnect trim sender lead and fuel sender lead from multifunction gauge and connect to new gauges.
