So in my quest to complete the precision aerodynamic homo sapiens transport, I decide to look up relay numbers for the last two I need. They are the 5 speed kick down bridge 928-615-125-01 and the manual start bridge.
So I get the package and what I have is one two blade module that has its spades at 90 degrees and a plastic push on connector that has the two pins looped with a brown wire.
The trouble is, I have no idea where they go. I removed two actual relays from the IX socket and the XIV socket. The parts I have are supposed to fit these slots (according to all charts observed vis a vis 928gt.com

Someone Help. Please.zp

I think the 928gt fuse chart has numbers mis labeled. They dont agree with Alans research.
The car is a US 928 five speed. Looking for the correct start bridge and kick down bridge and what sockets they jump.

Part numbers are correct according to PET and they are supposed to fit IX & XIV.

I think I need the 928-615-125-00 and 01. Alans relay chart says so. The part shown in the photo ( part #928-612-473-00) is shown in the 928 gts chart but will not plug into any relay socket.

WALTSTAR

My question is, when I get the proper jumper in the mail from Pepes, which
sockets do I jump with them?

Well, WALTSTAR, I don't think this is a GOOD ONE at all. Simply because I'll never be able to find it again, in a search for the actual topic. Just like "PLUG IT", "SOMETHING STRANGE OR NO", "What can it be now", etc. Sorry to rag, you have posted some good stuff, but why not make the thread title useful for searching? Check out Captain_Slow's, voskian's, crumpler's, or indeed almost all the thread titles on the 928 forum- crafted to help future searchers find whatever pearls are contained therein. You're not alone in needing to refine your thread titles, but you were simply a target of convenience this evening (I'm looking at you, Socal_Tom...). To me the greatest asset of this forum is information, and socializing only comes (a close) second.

The starter bridge 928.612.473.00 is correct. But it goes in the spare tire well above and in front of the battery (closer to the front of the car) under a plastic cover. It connects the coil 85 of the starter relay to ground (this is normally connected via the neutral/park safety switch on the transmission in an Auto. I suspect you probably already have one installed?

You also need a 141.951.253.B (standard 53B) in the Starter relay slot on the CE panel in slot XIV.

So one can conclude from this that Porsche thinks manual trans drivers are apparently smart enough not to start in gear but auto trans driver's aren't...? Truth - Roger?

The kickdown relay shows a bridge option - specifically the one you have 928.615.125.01 which WILL plug into a relay socket between 30 & 87 and bridges permanently the replaced relay's normally open switch terminals.

However in this instance Porsche made a mistake. You can install this bridge if you like in place of the IX Kickdown relay. However it is completely pointless - it serves to connect the kick down switch which you don't have on a manual to the kick down solenoid in the auto transmission which you also don't have on manual. It connects to this non-existant solenoid through terminal in the connector which (on an Auto) would be in place of the starter bridge 928.612.473.00 - via one of the empty connectors that isn't there in the bridge. So it does precisely nothing in a sort of triple redundant way!

How sure am I? - >100% sure Porsche screwed this one up - however it does no harm and you have one - So plug it in for looks alone!

NB:It can fit in only one way. Note that 928.615.125.01 is functionally directly equivalent to 928.615.125.00 (superseded - they look very similar too)

PS Please do rename the thread - as a public service (1984 starter relay bridge & kick down relay bridge?)

BTW - I will need to update my charts based on this realization. I will remove all reference to the kick-down bridge - that's just stupid. And the starter bridge will have to be added to the "relays" not on the CE panel table.

Definitely truth Alan ... but Roger will put a different spin on it for sure

But seriously ... perhaps the rationale is that, with a 'drive it yourself' manual, they were ensuring that the option remained for you to start in gear, because you can disengage drive to the wheels using the clutch ... whereas the 'drive it for you' will drive itself if you start in gear, whether you want it to or not.

Hi Alan - where can one find your charts these days, specifically for an 84 Euro?
