I'm in the process of soldering my obd2 alternator and distributor plugs to my obd1 si harness and had a question. According to the diagram below (distributor) i should have a green wire for tdc+ on my obd2 plug which isn't there, however i have a orange/blue wire. All other wires match up, should i assume the orange and blue wire go to the green wire on the obd1 harness?

Any help would be greatly appreciated
