I know on my ef it was a little light that bleeped. how the frick do u do it on a 1st gen dsm.

Here ya go aznpryd,
You can do it two ways... use the blinking LED or buzzer method or use a datalogger to pull the code. The cheapest and easiest way is to use teh LED or buzzer. You can go to Radio Shack 12v electric buzzer (Radio Shack #273-055 $2.49) and attach its leads to the terminal connector, then just listen for the pulses. Put the car to "ON" and count the long-short beeps (like Honda) which will give you your code. There's step-by-step instrcutions on this prcoedure somewhere online but I don't what it is right off hand. This should be enough info for you.

11 O2 sensor
12 Volume air flow sensor
13 Intake air temperature sensor
14 Throttle position sensor
15 (1.8L only) Idle speed control motor position sensor
21 Engine coolant temperature sensor
22 Crankshaft position sensor
23 Camshaft position sensor
24 Vehicle speed sensor
25 Barometric pressure sensor
31 (2.0L Only) Knock sensor (turbo only)
36 (1.8L Only) Ignition timing adjustment signal
41 Injector
42 Fuel pump
43 EGR (Ca. only)
44 (2.0L Only) Ignition coil, ignition power transisitor unit
short pulses only Normal state
