Checking Timing??

[Nixon1]

Ok..my Haynes manual says to either disconnect and plug vacuum lines to my distributor...which I don't have, since the car is a 91...so then it says to disconnectm a SINGLE-wire connector above my ignition module...well, I don't have one of those either. Only wiring above the module is a two-wire connector, that's just dangling there with a little piece of plastic clipped into it that's apparently made by Ford.. I also have a vacuum line running in front of the distributor, I'd guess it to be about a 6mm line..and it's disconnected but it's got a piece connecting it to another piece of vacuum line of the same size before it...but the piece must be a blocker because I started the engine and there isn't any vacuum leak. I need to check my timing guys! Car's a royal b*tch to start and it misfires when I step on the gas...AND I've got 92 octane in it right now, which is the highest octane sold here. I gotta get this adjusted!! Thanks.
