The electric throttle needs a bulb which is located in the speedometer of the E32.
But you can also use an external lamp. (About 2 watts)

[Grimmjar]

Yes, you don´t need the speedo or dashboard.
Just a 2watt bulb.

What you realy need is the Speedsignal!
If you don´t have it you´ll only get half power and that is boring...

thanks, 2 watt is also new info for me.
2 watt bulb on which Pin/line/wire exactly?
 Steckerbelegung Kombi

Seriously? It's in the link you posted!
 http://www.e32-schrauber.de/bmw/date...egung-x502.pdf -->x502 pin 16 and 17: "Kontrollampe" "EML"

checked to quick and missed that
thanks, Johan

It is x502 pin 16 and 17.
I have both wires on the bulb.

It´s looking like that:

12volt Batt. ===> 7.5amp Fuse ===> 2Watt bulb ==> Both wires on x502 pin 16&17

Both wires go to EML and during the Test EML will connect them to 0 Volt/Ground/Chassis ...


(i´m writing too slow..... )

Thx. Where does the ecu gets its speedsignal? I thought you could change the ecu to "manual gearbox mode" and that then it was ok..

Ps I bought the engine and other parts. The vendor is now parting the e32 out and 'll let me now when I can pick up my new engine..

Greetz,

Speedsignal comes from the rear axle differential.
But there is a cheap way around this.

btw.: what rear axle do you have?

[transeurope]

Rear axle is from volvo 245 turbo (1031 axle), can normally cope with 500NM.

[transeurope]

So I ask the vendor if he can give me the speedsensor on the reardiff as well?

Greetz,
