ive got a 1990 integra w/ obd1 hondata s100 ecu in it, need to know how to pull the error codes bc the CEL is on. ive tried searching around but havnt really come up w/ anything. i saw something on another site about a blue, 2 pin connector to jump to make it flash, but will i still have that connector if the stock ecu had a built in led light? i dont currently have the car here to look, but i will be going to look at it later tonight. any help is appreciated.
