WIRING SCHEMATIC
There are two unique wiring schematics; one for replacing a VLU
plus
with a PRISM TM and one
for a new installation of a Prism. For a replacement installation you will need to use the VLU to
PRISM TM adapter and for a new installation you will need to use the PRISM TM harness. There
are a couple of differences between the standard VLU and PRISM TM harnesses, in particular,
the PRISM TM ground is a bare wire and the PRISM TM ignition is orange.
