its not to hard to go to obd 1 talk to kenji he can make you a jumper harness. all you have to do if you dont use a jumper is repin the distbuter by matching up the color pins in the harness (due to the crank angle sensor on the oil pump)also get a obd1 dist and ecu.getting obd1 gets rid of the secondary o2 sensor and allows you to run a test pipe and get rid of unnessicary emmisions crap.
