Codes to pull?
If the computer has codes, will it make the emissions light come on or something? How do yo know if you need to get codes? Is there an easy way to do it or should I get a scanner? My books tell me what the codes mean, but just say to use a scanner. Most of the info I see on the net is for newer trucks. I have an 86 with EEC-IV

This explains that emission light
1985-87 LIGHT DUTY TRUCKS Control unit for maintenance reminder light is located under dash, near steering column or behind glove box. Some models use non resettable control unit. Replace it with a resettable type.
1) To reset SRI, turn ignition off. Remove tape over reset hole in timer. Lightly push a small phillips screwdriver into hole in timer unit marked RESET. With light pressure on screwdriver, turn ignition switch to RUN position.
2) Light should stay on while screwdriver is pressed down. Hold screwdriver down for approximately 5 seconds. Remove screwdriver. Light should go out in 2-5 seconds. If light does not go out , repeat steps 1) and 2).
3) Cycle ignition from off to run position. Light should glow for 2-5 seconds. This verifies proper reset of maintenance reminder light..
My 86 had the non resettable control unit, So i just pulled the bulb
But My Dads 87 Bronco has the resettable one, at some point i want to switch them out, since his truck has'nt run in 2 years.
