Quote:no on the back of the engine on a 2200 and i think 2.2 right above the oil filter theres a plug thats capped off that u can tap in to for your oil pressure gauge or turbo oil feed line. i think the s10's use that plug for something that the cavalier don't.
do you mean the oil pan plug?

thats if you have a 2.2 and its a tach adaptor. you only need them for the 2.2s because they didnt have tachs. he has a 2.4 and should be able to just hook up a tach directly

do you mean the oil pan plug? and why couldnt you run the illumination wire off any power source that only has power when the car is running like a fuse or something?
