I've in the process of adding some missing consult pins into my ecu plug and just noticed something odd, so I'm looking for some insight. I've been driving this s13 redtop for a couple years now and it has driven perfectly for a period in the past. I've been trying to pinpoint a lean cruise/idle condition, which led to me realizing my ecu connector didnt even have consult pins. Come to find out, after looking at the pinout, I'm missing a couple other pins altogether. The ones that are really boggling my mind are

8 - Ignition Signal #3
9 - Ignition Signal #4

How in the world has my car been running with only the ignition signal #1 and #2 pins connected?

All of the a/c related pins are completely missing too. Should I just look into purchasing a new wiring harness altogether; considering I'm currently trying to get my consult port and a/c system all connected and working?
