Injector harness question
 

Hoping for some help as I’m trying to finish this build.

im swapping a 2000 bp5A 1.8 into my 1990 NA6. (MS DIYPNP) I sold the 1.6 motor awhile back and left the injector harness on it. I was planning on using the 2000 injector harness to switch to sequential fueling and changing the wiring at the pigtail (I.E. add the two extra wires from the main harness side not the injector side) but I’m finding most people keep the 1.6 harness. Does anyone have a write up or diagram on how to convert the 00’ injector harness? Thanks in advance!
