i got a 1990 ef hatch (DX)
i recently did an auto to stick swap and swapped in a DOHC ZC and im relooming and fixing corroded connections and wires in my engine harness(1990 DX mpfi'd with cam sensor wires for ZC)
i came to find a wire is cut..(yellow) it runs from pin "A8" on ECU plug connector "A" can anyone tell me if i need this wire in my new setup(1990 dx hatch DOHC ZC) that was converted to stick?

i looked it up and it says tranny lockup selonoid and i understand thats only for auto trannys

the yellow wire runs through the drivers side round connector and to the looming that comes out to the head temperature sensors and dizzy plugs and 02 sensor...

 

did you change ecus to stick

 

I'm now using a pm6(si) ecu....
I just want to know where that yellow wire from a8 on ecu plug goes to...
and if I'll need it because it's laying around....

 

you wont need it because it has to deal with the auto tranny. A8 is the lock-up control solenoid valve. i dont think you will need A10 either

 

same thing I was thinking....
anybody got more input ....?

 

well A10 is also some auto tranny thing so you can get rid of both of them
