I came across this weird relay in my 1988 928S4 5spd fuse panel. I can't determine if this is a regular relay that the cover has come off, or is this some obscure 928 hack. This relay sits in position IV and is identified as Ignition Relay X (141.951.253.B). Everything looks as it should. Do you think I replace it with a normal looking one?
That's not a normal 53b relay. No idea what that thing is.
Yeah, I noticed it was much taller than the normal #53 relays. Given that this is for ignition, I wonder if this was part of some ignition timing mods? Hopefully one of the chip tuners will chime in.
The car starts, runs, drives, very well. I guess I could replace this with a normal relay and see if there is a difference.

That shouldn't do anything with the timing. Swap the one from the horn in that spot and see what happens.
The extra resistor,cap and all those diodes suggest that it's doing more than a "normal" 53B relay. There are suppressors and such fitted in specific places. Being the detail-oriented guy that I sometimes am, I'd have it out for some circuit sleuthing to see what someone built.
Are there any unusual warning light behaviors when the ignition is switched on? I would also take a look the back of the CE panel - might find some interesting wiring there.

Right, maybe was part of an anti theft device ???? some type of immobilizer....but good idea to look on the back of the panel for other modifications before simply plugging in the proper 53 relay.

There is no unusual behavior. The car starts, runs, drives fine. There are no funny indicator lights either. The car does have an aftermarket alarm (Clifford) that appears to be from the 1980's maybe this is associated with the alarm. I'll give it a quick check tonight.

Pretty interesting. I'm really wondering about the resistor, and probably on the wrong scent here, but just a WAG is that this setup is to emulate some normal functionality, like warning light self-check or something else that happens on startup. Really do want to hear about the back of the CE panel, and maybe ignition switch- does that wiring look normal? And the aftermarket alarm may be a clue, but why would it take that kind of rework of the relay? One last thought, if the back of the CE panel looks stock, one might try sticking in a standard relay and seeing if anything is dead that shouldn't be, or if electron smoke is leaking out anywhere (notice I said "one" - I prolly wouldn't do it myself...). Keep us posted, please!
Am I missing something? Based on my reading here, Isnt this supposed to be the window relay? The part number you mentioned doesnt quite match up with the generic number I found based on it. To be sure, I'd say pull it out (Disconnect the battery first!) and then try starting the car w/o it and then test the windows. Either way a relay with a loose cover is a gamble, and wound up smoking my electric board on several ground wires while driving because of it.

Holy crap! Your are absolutely right. I transposed the roman numerals when cross referencing the location. The relay in question is in VI (Window relay 928.615.126.00) not in location IV (ignition). Thanks for the good catch!
The windows do work normally right now. I will test by pulling, and get a replacement as you suggest.

Do I need to replace this relay
