Can anyone help. I have got a 91 crx with a obd1 ecu connected which has been remapped. I brought a apexi afc neo for the car cause i put in ITR cams. I brought a harness from boomslang so i could connect the afc neo with ease. but when i connected the harness the car started but wasn't running right and i noticed the engine management light came on then the car just died.. i thought it was battery cause it looked as if the battery had just died. but it wasn't.. I took the harness off and then tried but the car still showed no sign of life... does anyone know what has gone wrong
