Custom Dash, Check engine light troubles?

[luskeyclassics402]

Hey All! Say I've decided to take on the challenge of putting a custom instrument cluster in with all auto meter gauges and I had a quick question, AS far as the check engine light goes, is it a regular bulb with a connection in the back or is it wired into the circuit bored? I'm considering relocating it and i guess it could be a real pain if its in the circuitry. lol Let me know if anyone's done anything like this. By the way the build is a 1988 k5/v10 blazer with a tbi 350.

the bulb is a simple +positive and -negative connection
you will need to trace down the wire that is hot for only a few seconds during start up, the ground is obvious. Just run an LED somewhere for the light.

When I did mine I used this off 73-87.com

[SIZE=-1]#1 Lt. green = high beam indicator lamp. #2 Gray = instrument lamps. #3 Black = ground. #4 Pink/black stripe = ignition. #5 Tan = oil pressure sending unit. #6 Pink/black stripe = ignition. #7 Pink = Fuel (will be spliced to #18 if you have dual tanks. Use the wire from #18 to hook up fuel gauge). #8 Black = ground. #9 Dk. green = water temp sending unit. #10 Black = ground. #11 Lt. blue = left turn signal indicator lamp. #12 Dk. blue = right turn signal indicator lamp. #14 Yellow = fasten seat belt light. #15 Md. blue = choke warning light. #16 Pink/black stripe = ignition. #17 Tan/white stripe (2) = park brake warning light. #18 Pink (2) = Fuel gauge sending unit (splice to other pink wire at #7).[/SIZE]

As I recall, #15 was the CEL.
