When it comes to small shots simpler is always better. Run it through the MAF and on a simple wide open or window switch. Since your truck is DBW put the wide open switch under the pedal

what i read from the instructions, it said to use the lead wire on the tps or dbw to tap in for the wot switch, so you have to program the box with a series of pushing the button on the box and holding the gas down. i didn't put the n20 before the maf per the manufacturers instructions, and i wasn't there when they decided it would be a good idea to use speaker wire to extend the box wiring, so i will be re doing that. and the box has two vacuum lines that you put one directly to the vacuum port on the fuel pressure regulator and the other one on the vacuum port that was supplying vacuum to the fpr.

Man this setup is way to complicated for a 75 shot. If you are having wiring or jet questions at this power level you need to get help. Go to Allen's, shit go to any trustworthy shop. If you dont you are going to be a poster child fot the "nirous sucks" movement. If you only have one noid, spray it on a wot switch before the maf. If you have 2 noids insert 6 inches before the TB and jet accordingly. I am not an expert, some others on this board are. This is coming from experiance, experiace I have learned at the cost of heads, pistons and much more. I call it like I see it. I see you headed for disaster if you keep listening to your "buds" we need to know nitrous pressure, fuel pressure, jet sizes, and fuel pressure. I doubt you have a wideband O2 at this point, so I would suggest your first runs be done on the dyno, if the WB02 reads leaner than 13.6I would abort the run. We are all here to help you we just dont want to see you trash good heads b/c of a lean condition.

not saying youre wrong, but i have just hooked it up per the instructions, i think its pretty simple, i just dont know which wire is the right lead wire and i may just have a bad box since the light wont come back on

its got all of three wires, two vacuum lines, and a feed and supply line for the nitrous. still not sure on bottle pressure, and i think the pill said 38 but when i looked online that was a 75 shot
