Engine Wire Harness Question

[MBZ300CD]

1986 4runner turbo.
I had to pull my engine wire harness to repair damaged wiring to the igniter. In doing so I came across what may or may not be an issue.
The wire dia. shows the wires going from ECU port No. 10 going to # 2 and # 4 injectors, with No. 20 going to #1 and # 3 injectors. Addtionally, there's a note ( Ex. 22R-TE ) indicating they are not connected. However, my harness has them connected. Or maybe I'm being too anal or I'm wrong?

The splice is obviously not factory. Also the wire color on on one set s/b white with red stripe, but are all just white. Vehicle was running fine b4 as far as I could tell.

I went through the harness, corrected that issue and re-did some other splices. I also added quick release injector connectors, re-taped and added better heat insulation to the rest of the harness.

Did the cherries growing out of the harness shown in that first pic have any effect on performance ?
