That color image is an integra GSR harness, it is semi-wired like EG civics. disregard somewhat.
Easiest way to lay a harness down, start with what is easily identifiable. TPS, MAP are matching, and critical they do not exchange, so start with those, based on wire colors.
Then find the colros for the fuel injectors, make sure they do not get mixed up.
driver side has the big grey plug that has a bunch of 12v wires bridged under the cap, easy to spot and locate.
alternator plug and charging wire is easy, but since routed under the intake, can be tough.
I suggest removing intake manifold for ease of access
