I've searched but I'm still stumped.
'89 MJ
1- Left front parking light will not illuminate (right is good)
2- Works when signaling/flashers, although dim (only one filament is on)
3- Left turn indicator dash light is on when parking/headlights are on
4- Bulb is OK (switched in one that worked)
5- Swapped in two other harnesses (I KNOW one worked when pulled 3 months ago) still the same
6- According to the wiring diagram (see below) the left uses pin 3, the right pin 8, and both share pins 4 & 5
7- Voltages were the same at pins 3 & 8 (engine side)
What am I missing? All three harnesses can't have the same bad socket or short, can they?
