Service engine soon light

[harvey85]

To explain, all the vacuum lines on my electric quadrajet had no hoses. As I tried to figure which ones needed to be plugged and connected, I had put my finger over the manifold pressure tee a couple of times and I assume this is what gave me the service engine soon light. Strange thing though after I got the vacuum lines plugged and the distributor vacuum advance hooked up, I still had the engine light on and my voltmeter was pegged left about 9 oclock and oil pressure pegged past 60. Any help as to what could be the cause would be nice. Still trying to find the ALDL switch to see if I can figure out what the code is, but the gages are really throwing me for a loop. Truck runs fine, use it as a daily driver and have had no issues driving with the service engine light on.
