LED bulb install, right side blinks fast, left doesn't

[dictoresno]

Installed some new LED replacement bulbs in the rear of my 1986 911. Replaced the reverse lights and brake lights....no issues. Figured I would have some issues with the turn signals so I took a chance. Replaced them with some 1156 Auxito bulbs, as I have with all of my cars. When ONLY replacing the rear turn signal to LED and keeping the front the stock incandescent, the car flashes normally on the left, hyper on the right. I was able to mess with the front bulb and then the right flashed normal for a bit, then back to hyper.

hazard lights flash normal for all four corners with LED rears and incandescent fronts.

any simple reason for this besides the usual resistance issue? I was considering getting an LED compatible flasher relay at the below link. any way to tell without removing the stock flasher if I have a 3 or 4 pin? also noticed the cars turn signals have NEVER clicked when the turn signal flash. is that normal?

Schematic for Carrera 86 shows a 4-pin turn signal flasher relay. They are labeled C, 31, 49a and 49.

I saw that however everything I see for physical replacement is showing it’s a 3 pin. The ground must be internal. Unless someone else can chime in, I’ll have to pull it later to be sure.

The fourth pin used on the 4-pin relays is for the "trailer turn signal indicator".
So unless you have that trailer thing (don't know what that is), you can buy the 3-pin version for LEDs.

Grabbed this one this morning after reading a few forum posts. Gonna install later.

LED's are directional as I learned with my dashboard, if one didn't work, I'd take it out and turn it 180 and re-install.
