just had a quick question are all obd1 pinouts the same the reason i ask is i have a 91 prelude with a jdm b20 and the car is obd1 but the stock engine has egr crap on it and the jdm one does not have this stuff and i did not want to transfer it over so to eliminate the CEL i want to run a p75 ls ecu that i have but im not sure of the wiring on my ecu and i can not find a pin out any where i can only find them for the obd0 88-90s so any help would be great
