Hey guys,

I am trying to set up my friends truck with an lm-1 air fuel meter and wanted to try to get a signal from one of the coil packs that is easier to get to. I am on the #5 green wire w/white stripe. Doesn't seem to work. I get a signal but the measurements are just all off. I know that the other wire going to the coil pack is not it either because it doesn't give me a signal. Just wondering if i have to get the signal from the #8 like i have seen others do. Thanks.
