my buddy has a computer and i wanted to hook it up to see why my check engine light is on but cant find the where the plug is. can anyone tell me where its hidden. thanks

 

first you need to tell us what car you are talking about

we need the year

 

**** it

if you have a 95 and older (i.e) 95,94,93, and so on, the plug is on the pass side attacted to the back of the support beam right under the glove box.
you need to remove the glove box the there will be two conectors one is big, one is small only a two pin conector that is the one you need
all you need to do is jump the two wires with a paper clip and turm the car on to electric, dont turn the car all the way on. and your CEL will start to flash

long flashes = 10 short flashes = 1
example _______ ______ ______ --- that means code 33

if you have a 96 and up its on the driver side under the dash by the gas pedal i beleave just plug the computer in and read what it says
