Would like to purchase a known good working EZL for 1989 560 SEL. NEED TO TEST/ rule out ezl . Also, would different v8 fuel pump relay part numbers affect idle speed and smoothness ?

Thanks forum

I would absolutely not swap EZL's until you install a new ignition coil. A shorted coil can destroy the EZL. You don't need TWO bad EZL's.

125 coil solves a lot of crappy electrical issues, along with good grounds, etc.

Ok point taken. NEW coil first then we will see where we stand. What's this business about right side or left side coil? Are there 2 oem part possibilities ?

Yes, look at your coil first. If the connection points in to the engine, get that one even if the part nbr is different than the epc or autohausaz number. Same part just different orientation.

There's just one coil on your '89 and no OEM options that I'm aware of. Use your VIN when ordering.

This is what I was referring to Mike: Your Parts Search Returned 2 Part(s) Coil

I have tried both and they all work the same regardless. It just a matter of orientation and which way is easier to make the connections.

they are identical (my cousin vinny) but mine is so tight in there I would hate to buy the one on the wrong side and not be able to get the blasted leads up to the nut...grrr I would most likely punch something and break it LOL

I always thought a disgruntled employee at Bosch flipped the blueprints at some point. Just because....

Got it. Glad to know this since I'm sure there's a coil in my future...
