simple as this
HUD into non-HUD car..what you need
89-90
or 91+
89-90 into 89-90 requires HUD cluster, HUD subharness (plugs back into cluster and onto main harness)
cut of dash for actual HUD or swap dash
direct bolt in
91-94
HUD cluster
HUD subharness
plugs right in
to use actual HUD display, need to cut dash or swap dash
direct bolt in
89-90 HUD into 91-94
wiring modification, RPM swap
91-94 HUD into 89-90

basically:
stick w/ the same year cluster as your car
89-90 use 89-90 HUD cluster and subharness
91-94 use 91-94 HUD cluster and subharness
