s13 hatch with sr20det wiring issues

[1slowM6]

I have a 1990 hatch base model with a 1993 hatch base model chassis harness front to back that came out of a running driving car with a Ka the 1990 has an sr20det in it with a brand new wiring specialties upper + lower harness and I'm having issues with it.

My ignition isn't working not sending any power or turning off power it's not doing anything or sending any signal... And we put direct power to constant power wire on the grey plug and now the fuel pump and ecu stay on unless you unhook the battery... Starter has to be jumped aswell

i would contact WS as i believe what you bought is 'plug and play' though its not working

does the ecu light up?

Those harnesses are plug and play and i have never seen any issues. Contact Wiring Specialties directly for assistance.

Great easy to use products.

Also check that the ECU connector is 100% seated, i have had this issue numerous times where people will think it is fully seated but it actually is not.
