LS 5.3 stock fuse box fire up on stand and how to delete vats for free 

I shouldn't have to change anything should I??

not if you dont mind the stock fuse box there will be a lot of it will be unused

thank you i appreciate it

yes its fine as long as it turns on ,it will continue to work as long as you dont clear the code for the bcm ,ive been driving the car i put this engine in for over a year

since you already pulled it out of the donor vehicle you'll have to send your ecu out to get them deleted got to lt1swap,com i had them do one for me for 75$ about a year ago,theyll delete the vats,delete smog ,remove governer cuttoff and program to your rear diff gear ratio and tire size for transmission , best deal i found so far

are you talking about the yellow and pink wire i used to start it?

yes its the stock gas pedal i don't remember any hose coming off the gas pedal just the plug going to through the firewall to the pedal control module i didn't have to do anything to that part of the harness

Ive never fire up an l98 tune port on a stand i did have one in my 56 f100 that had a stand alone harness from painless wiring and the computer had already been flashed with that being said ignition wiring pretty much the same those injectors were 45 psi

no gerardo I havent had to replace one yet

this is for 03-07 id check that you have a good ground from battery to block ,good constant 12v to fuse box ,and that neutral safety is in park .

@ozcorr909 it ended up being my fuse panel itself. Swapped it for a different one it worker perfectly. I have everything from a 2000 tahoe

right on im glad it worked out

I cant get my swap started, no fuel pump prime or starter , could it be because i dont have my transmission and the sensors hooked up ?

if you are using the neutral safety switch make sure its in park or it will not start ,i put this motor in my car about a year ago and is still working without having ecm programmed .if you clear the codes (check engine light) you will have to get the ecm programmed to remove the vats and whatever else you need removed,i used LT1swap.com to program another one for me .

thank you sir i appreciate it

supposedly thats what they do when the vats are not deleted,are you running a fuel pump if so check that it is coming back on after initial priming .

C1 PIN a3

c1-a9 pink wire power from ignition powers up fues block, c1a3 yellow wire provived power to starter relay it will not work if neutral safety switch is not in gear,you can bypass the neutral safety switch by running your ignition starter wire straight to the starter,

yeah that works too

sorry i dont have one

@@ozcorr909…. hey what’s up, bro? I have a 2003 Chevy Tahoe that fires rite up and runs great when parked and on take off but gets about a block away and dies for no reason but will fire rite back up….Is that the VATS??…. if so, I need to try this trick unplugging it.😎
