Time to de-pin my swap
Ok so I re-pinned my 98' LS1 pcm plugs to a 99' config and going to run the #12200411 pcm. I'm ready to start cleaning up and de-pinning. Can I just run down the 99' diagram and delete ANYTHING that says or has to do with A.C/ Trans/Emissions besides front O2's/Cruise/Fuel Tank? Here is my rundown.
1981 Chevy C10 1/2 to 2wd
Engine and harness from 1998 F-body LS1/T56 drive by cable
PCM #12200411 Vats/Emissions turned off and all unneeded
A.C./Heater- None
Fuel Pump Sys.- Pretty much standalone in-line vette filter
Emissions-Turned-off and looking to depin
Trans- Th-350(Vacuum lockup) with Dakota VSS
Park Neutral wired into stock truck switch
Speedometer-Cable
Cruise-None
Guages- Stock
Cooling- Stock Fbody rad and fans
Fuel tank- Stock truck
Pretty much the simplest setup anyone could aks for lol

you seem to have a handle on what you need to know.. just double check everything to make sure you don't leave out anything that needs to be in the harness..
best to lay it out or lay on the engine with the connection connected. then see what you can remove.. and double check which pin.
But as you can see, there are many threads to read on doing this and what you can delete.
Good luck

Any Arizona boyz wanna chime in on problems with emissions stations and swaps. I will have everything lookin like it works and no OBD2 port(at that time) but what standards do they have to go by? The truck or the motor? Do they wanna try and scan it? I have been ROUNDS with my station SEVERAL times with every veh I have owned soooo and half the reason for the swap! I would send the little blondie in there but the managers a bull-nose.......
I had a 88' 4 door shortbed turbo'd TBI 5.7 built to the hilt and when the lil ricer dude popped the hood on it first question asked was. "Dude is this a diesel"????? Really? So one by one they came over, fap fap fap.......fap fap. Didn't look for sh*t and said "dude thats dope, pull up." lololol but that was another station.

Agree. you don't have to removed the A/C or Emmission part of the harness.. check to see what you will need to use to pass a State Smog Check..
Most state Smog tests are based on Calif C.A.R.B standards.. so. you well have to use a newer engine that is the same or newer year than your truck. then to recert it to the Engine's standard (year and model of the car/truck it came from)
But since your using a 99+ "411" PCM.. you well have to match up all of the 99+ LS1 smog equipement (Cats, intake, exhaust, EGR, PCV, EVAP, etc). You will need to reflash the PCM with a new program and VIN.

Will do BC. I don't think it would be to hard depending on the application. But ya never know with CALIFORNIA! Our year for emissions is even farther behind than yours (1968) and I think you guys are up to 1975??? Our collector plates have like a 2500?? mile per yr cap to
