m10 to m20 harness wiring.

[Inxcesof]

I have completed the mechanical swap from the m10 to the m20. This included all the suspension and rear subframe, engine tranny, harness, driveshaft amd cooling. I am having trouble with the splicing of the 2 harnesses. Has anyone done this swap if so do you have a diagram for the wire to wire colours from the round plug to the square plug. Thanks alot for looking

Search, I've posted the detailed wiring required for the swap at least 2 times I would post it again but is a lot to type.

Schnell You mean they plug to convert the 318i body to the 325i engine plug? If so sure, you still have to do some minor wiring. Like for the tach and what not. Only problem is the current one i have is a little short but I can lengthen it for you realy quick before you buy it if you want it. Send me a PM and we'll discusse a price.

[Inxcesof]

I just put excel on my pc so i can read it in the format you made it in.

[Inxcesof]

if it is easier i will buy one from you. I have an entire spare 325is harness

[rs4pro3]

it depends on if you like wiring and can solder well. I only have one right now and have the material to make half of one I need a 325i chassis side engine harness plug to be able to make two. I solder and shrink wrap all conections then will wind the wires up very tightly with electrical tape. I had to do some work on a body harness I sold and it looked factory once done. It just all depends on how good your wiring skills are. LIke I said you still have to wire in those extra wires used for the tach and some other features like check engine light(if you want it).

[Inxcesof]

well if you want to post or email the excel version of what wire to what i will try to do it as soon as i get it. If it dosent work i can send you a entire harness and pay you to do it.
thanks
