Also added a Wire-Gauge Table showing the AWG sizes required along with the corresponding connector pins. Very handy table!.
A caveat via my story: when my ETA failed, certainly the wires were toast so it's amazing that it worked as long as it did. However, the butterfly "clutch" burned open and that was the "real" failure that caused the LH and other ETA going-bad anomalies. The wires, as bad as they were, were not the problem (at that time) b/c the ETA harness had never been disturbed. Also the reference pots were worn but still ok.
So the point is that you still need to inspect (and dis-assemble) the complete unit if you are a DIYer; the wires are certainly one large factor in the failure mode but they are not the only one that can cause a ETA failure.
Using Victor's "ETA-static-test" video
should show if there are some gross failures, so, absolutely, it should be done.
Shops like Beckmann Industries have a real M119 test-jig that completely tests the ETA in a closed servo-loop. Bad parts are immediately spotted either BEFORE or AFTER re-wiring of the unit. That test jig is a wonderful thing . . .
