I want to remove the obd1 harness in my EG and replace with an obd2 harness for my JDM ITR motor. How hard is it to replace a wiring harness? any instructions?

OR is there any easier way to make the JDM ITR engine work with the already install OBD1 harness? I figure that cos the distributor/etc is different it is better to change the whole harness or can i cut 'n splice?

 

c'mon i know some of you have done this before!!!

 

make an obd1 to obd2 ecu harness

 

Stick with OBD1, you have more fuel management options and less headaches. Some guys like to cut and splice the distributor wiring, I prefer swapping distributor guts (cleaner) . Another benefit of OBD1 wiring is that RC injectors plug right in-no clips required
