S52b32 - right electric conector

[gianluca1505]

Hello Guys,

I'm Gianluca from Italy . In this week I posted with my bad english a lot message in this forum, in techical posts of s52b32 engine.

that is my history :

I have a my bmw z3, year 2000 , second body edition, with engine M52B20 TU - 150 HP . last year I burn my original engine and , with my lucky , i finded a crash car : one BMW z3 M coupe 1998 with engine S50B32 - 320 Hp . So I buy this car and I made the trasform . I change the brake, the differential, the trasmission ZF, and all motor. That work it was very easy , because I buy not only motor , but all crash car , so I had all component .

Now I finish the mechanical trasformer , but start a very big problem . the electronic parts . From a lot diagrams I find that the electric plant are the same , but the engine link and instruments cluters are different, but that have the same original.

So , i read in your forum that a lot people put inside the E30 cars , the S50B32 engine , so a lot people make my same difficult, so I ask if that peoples can help me , because I'm good "sunday mechanical" but I not electrical people.

I post the picture of my work.

Ps : i'm sorry for my bad english.
