I just got a b16a ef its an si has obd1 wiring auto jdm p30 ecu ... Im trying to get everything set on on I hate seeing car not working how they supposed to. First thing I did was check the codes I have.
Code 19 A/T lock-up control solenoid
Code 20 Electric load detector
Code 23 Knock sensor
Code 41 Heated oxygen sensor heater

code 19 has to do with the auto ecu i guess
code 23 I need a knock sensor plug and wire it to the ecu


the problem im mostly posting is about code 20 eld I think ef are supposed to have it on the alternator and newer vehicles have them in the fuse box... so what am i supposed to do if I have a p30 ecu is there a way to fool it or can i wire it to the one on the alt ?

for some reason my headlights all work as one meaning i have high beams and lows together even if i switch the button it only works that way why is that?

btw it has an crv cluster in it i dont know if that has to do anything with it.
