I went through the schematics for the x20 on a 94 525i and a 94 540i, and they were identical. Wire size, color, pin #, and function, were all the same. Which means you should be able to use the common info in the 24v subforum. The conversion chart will depend on year and model. All early model cars with a square c101 should be the same, but round c101 cars vary in at least 1 or 2 versions. I can send you my chart for my 85 325e -> 94 525i/540i if you'd like. But use it at your own risk...
I stopped using charts from other people after I melted an m20 engine harness using second hand info from this forum (+12v vs. ground, on the same pin at c101). I just go right to the ETK and do it myself now.Leave a comment:

M60 X20-C101 Harness Adapter
As a lot of us get closer to having our swaps completed, I thought a harness adapter chart might be a useful addition to this sub-forum. I searched yesterday, but didn't find anything specific to this swap. I did find a plethora of E30 C101 charts and quite a few M/S5x charts, but nothing for our V8 swaps. Has anybody done an excel chart or care to offer up their info here? Just thought it would add even more credibility to this sub-forum being the "somewhat definitive" V8 swap forum, lol!

Oh, and I would use said chart for my car, since I'm ready to make the adapter now, haha...
