In building a new engine harness, what's the best way to deal with the numerous GNDs connecting to the ECM?
On my 3UZ (6-speed) ECM:
B2 (EC Chassis GND)
C1 (E02 RHS cylinder head GND)
C2 (E01 RHS cylinder head GND)
D4 (ME01 RHS cylinder head GND)
D6 (E03 LHS cylinder head GND)
D28 (E2 sensor GND)
E7 (E1 LHS cylinder head GND)
(Did I miss any?!?)
Apart from D28, all the GNDs effectively connect to the chassis somewhere, so where do people connect them? I was planning to connect B2 to an M6 terminal screwed into an M6 RivNut riveted into the chassis near the ECM (which is going to be under the dashboard in my conversion).
Based on the Lexus EWD, I also have E7 connecting to the same point as B2, and the other GNDs simply go from the ECM to the cylinder heads, but is that right? Any advice would be appreciated!
Cheers,
