pretty productive weekend, a good mate of mine came passed to lend a hand so things went alot quicker
My sedan used to be carb, but converted it to obd2a to use the ITR ecu that came with the motor. this was a mission to wire in most things individually, so this time i decided to install the SR4 180i harness (OBD1) then get a jumper harness (with added Knock sensor) from obd1 to obd2a to match the P73 ecu.
Luckily for me, the ITR engine harness can be plugged directly into an obd1 harness as its a 2 piece design where as a ek4 uses a 1 piece design.
Found out how expensive a jumper harness is thanks to our exchange rate ($200 for a bit of wiring) soooo a friend offered to help me out making 1
started off comparing the plugs currently running into my ecu, then confirmed that i can indeed plug the ITR engine harness into the SR4 harness
some repairs and alterations done
got the harness in
Next i grabbed a spare ecu i had lying around (b18b obd1)
Soldered the pins out
salvaged obd2a plugs from a ek4 harness
