i just dropped my L98 in my iroc and of course it was awhile ago and things get misplaced or what not but i cannot figure out where this plug goes it is in the back near the dizzy it is NOT the plug that plugs into thevacmun thing under the coil it is plugged in already wire is i think orange with a black line and the other wire is black

also not quite sure where this one goes its up front near the plugs for the TB and the maf/map which ever it is

 

second one is for the alternator.
not sure on the first one

 

in my best carlos mencia "dee da dee" i knew that second one was something easy

 

The first one is probabley for that pig tail for the IAT sensor.

 

is that the one that plugs in on the bottom of the plenum?? if so i already have that hooked up

 

First plug looks like the "set intital timing" plug to me. Plugged in to dist. it allows ECM to adjust timing. You unplug it to set the static timing... then plug it in to drive. Should be a female mate to it back there off the dist.
