i swapped in my y7 into my ef dx. using a 93 dx intake mani, distributor. bought the obd0-obd1 ecu jumper harness on ebay andhad to run 2 extra wires for the injectors, and 4 wire o2 sensor. put new dizzy cap n rotor. crank but no start. any help? also check engine light on but think the ecu isnt hooked up to the cluster like obd1 to throw the code??? any1 know how to wire the ecu to the cluster so i can pull cel codes???

 

Your conversion harness should have a yellow wire that needs to be grounded out to read the codes. Is the conversion harness made to compelete the dual point to mulit point conversion or is it for the ex si model? The si ex hf conversion harness will not work in the std dx or lx. Did you did you add the wires for the new dizzy? Did you rewire the dizzy for obd1.
