I was referring to the coil that sits underneath the fusible links. There is a yellow wire on one terminal and a black on the other. If you splice the tach wire into the yellow one your tach in the car will read.
Glo, Glo, Glo...Both of my EJ swaps were from 5 speed Legacies both being year 1990. Meaning I never hooked it up. Ever.. That neutral switch means nothing to this ECU in a manual, how the hell would this ECU know whether the car is traveling 1 mph anyways? Are you sure you're not confusing this OBD I ECU with an OBDII?
This OBD I ECU is not as complicated as it is being made out to be. Geeezus.
Your ECU is just doing a good job of compensating and keeping the engines running.....some ECUs have a harder time than others. But there is a Nuetral switch in the system, and it has an effect on the Closed loop operation. Your ECU just basically is seeing you're engine as in gear all the time. Your particular driving style could be preventing symtoms......But those who put the clutch in around turns and coast in nuetral to a stop HAVE reported problems with stalling and/ random high idles..
The VSS is how the ECU knows the car is moveing. Duh..
I have done 9 swaps in person and stripped wiring for dozens more board members....OBD I, OBDII, EJ22, EJ18, EJ257 and EJ20G........and a few SPFI to EA81 swaps.
I am trying hard to give helpful, accurate, thorough information.
Do you have your CEL hooked up.?.....If not how do you know if it's not causeing a CEL and an Open loop condition? (loss of mileage and possibly power)
Anyhow.....Ystirday......nuetral switch is in the transmission of FI cars.......if you don't have one on your trans a common "hack" is to wire it through a Clutch switch that is ussually used for Cruise.....can be scavanged from any MT legacyor other w/ cruise. Mounts to clutch pedal bracket
Wire so clutch "in" is like "neutral"
Green/White is OIL light wire (not fuel, Scooner) and the White/Green is temp....as mentioned.
