Just wanted to know your thoughts on this way to buy time till i actually get the car tuned after all the parts go in?

If your just doing headers just don't run any in the rear and you'll be fine. Tuning will turn the light off. You need working front ones though.

I understand u don't need them but will it work to get rid of light for inspection

this will work, if you know your vehicle specific info...
(resistance, wire colors, etc,)

so in theory it will work if i knew the info i understand. So i shouldn't waste my time and just leave the o2 wires tied up till i finally get a tune

thanks enough said

U have to pass emisions? or just the looky-lou test?

If the latter, just pull the bulb out of the dash...

I have to pass emissions and they hook it up to a computer to read the ses light

I made mine and they worked for about 3 weeks then burnt up. i have mine tuned out now, but if I had to do it again I'd try the sparkplug defoulers

when you have your rear 02's deleted the computer is telling the front 02's that the rears are within the proper parameters thus causing it not to run to rich or lean. you can just the rear wires and bungs in to appear in operation.
