No dash or taillights

Check fuses first. If they check good, make sure there are no body ground wires off, damaged, broken ...

Where can I find the fuses on this car ?

Also, Where can I find a harness plug & the left side cluster switch?

Hello,

Here is a fuse testing guide and a wiring testing guide as well:

Please let us know what you find.
