how do you hook up an oil pressure guage to an 04 cavalier? also does the air/fuel ratio guage hook up the purple wire on my car or is it the gray one?

i've also heard about something called wideband. my car isn't wideband is it?

No ur car dosent come with a wide band... I would suggest AEM or Dyno Jet wide band, As for the oil pressure gauge save urself a future head ace and throw away the plastic tube( If its Mechanical) What i did was use braided steel line with a fitting to thread onto the gauge, ran it out to the front of the motor where the sending unit is , unthreaded it, threaded in a "T" then threaded the sending unit back in to it.Then threaded the steel line onto the last fitting, u may want to get a shop to make the "T" and the line with the right fittings. Been running mine like this for 3 years with no issues, Hope that helped!!!

my oil pressure guage is electrical. it came with some sensor that screws into the front of the block but that requires my idiot light being unplugged. will my car run if i do that. Nasty car by the way

Thanks man !...It will run still...but u will need to watch that guage like a hawk in case of pressure drop.

cool. yeah i can do that.

one more question what is the thread size for the sensor that goes into the block

Not sure off the top of my head...I took mine to the shop and they matched it up.
