Oring looks like an oil pump pickup tube oring. The trans part is the PRNDL switch.

The part from the heater hose is the cut-off valve for the heater core. Only the SUVs had it on the old body style. It uses vacuum controlled by the AC unit to shut off the flow to the heater core when the AC is in use. You can eliminate it or plumb it into your new heater lines. You would have to add the vac lines to the intake if you want to use it and there should be a solenoid that attaches to it on the vac line.
I would just ditch it, like I said before, none of the trucks had it only the SUVs. That part is prone to develop leaks too.
ok i didnt see tha oring til i pulled the trans. any chance it could have came from the back of the trans where it connects to the transfer case?Quote:

yea sounds like a lot of work so ill just ditch it and run the hoses straight from the water pump to the heater core. thanks!Quote:

not home right now but its about half the size of a spark plug lol so maybe 2 inches maybe lessQuote:

not sure how you got it together with the shorter bolts but yes, pull it apart and put the correct bolts in it.
yea i guess better safe then sorry. plus i realized i kinked my trans cooler lines so might as well pull it all out and fix everyhting. also do you happen to know the part number for the serpentine belt to use when u remove the a/c? im getting ready to order the last few things and should be ready to fire up next weekend.Quote:

oh...awesome thanks! also kudos for the quick response bud!Quote:

only issue with the harness is that iwas from a 2003 6.0 motor and the guy got it modified to work with a 700r4 trans. luckily i still have my original harness so i can just grab the wires and plugs i need from there and add them to the new harness. going out of town this weekend so hopefully when i get back all my stuff will be here.
heres the pedal i needed.

heres the new harness fuse box and relays all hooked up
http://i1105.photobucket.com/albums/...y/IMAG0578.jpg
also the harness came with this plug that says vss where do i plug this in?

I read somewhere that you are going to change this from a 4WD to a 2WD. If this is right. does anyone know if a 96' Tahoe transfer case will fit into a 99' Suburban? Because if it does and you want to sell it I am VERY interested.
yea that the plan but not right now. i plan on looking for an 80e firstQuote:

yea i got it now i was looking there but i dont have a tailshaft because its 4wd. its in the transfer case. i havent checked it yet to see if its the same plug. but if not ill probably have to grab it off the stock harness for the truck. dude i saw your video thats awesome. win any races yet?Quote:

ok so i took a week off from working on this thing. actually went outta town for a short vacay. im back and ready to get this thing finished up. got my dirty dingo mounts in the mail and they work perfect. should have used these in the first place!
http://i1105.photobucket.com/albums/...y/IMAG0584.jpg
http://i1105.photobucket.com/albums/...y/IMAG0585.jpg
also i had to drop the tran because i used the wrong bolts to hook up the flywheel spacer to the back of the motor. so i dropped the trans and installed the new bolts.
http://i1105.photobucket.com/albums/...y/IMAG0583.jpg
http://i1105.photobucket.com/albums/...y/IMAG0586.jpg
also theres a shot of one of the holes i had to make longer to make the 5.3 flywheel work with my older 4l60.
i also ordered the vacuum adapter fitting from gmpartsgiant.com..the part was only like 4 bucks but they charge 11 bucks for shipping and once i got the package i seen why...they used this huge box wirth a huge envelope inside to ship a part no bigger than a AA battery smh!
http://i1105.photobucket.com/albums/...y/IMAG0587.jpg
Woooohoooo making some progress myzterray! Glad to see it all coming together.
oh yea...home stretch..gotta wait on lt1firehawk to let me use his hoist again so i can pull the engine back out bolt up the trans and drop it back in there. i was trying to bolt the trans up in there last night but couldnt get it leveled and lined up. so i figure grap the hoist...less frustration. all thats left is...fuel lines..starter fluids and pcm.Quote:

oh it will be a glorious glorious day when i post the video of it starting up! and i forgot i still gotta get the pedal modified.Quote:

What is that vacuum adapter fitting? I've never seen anyone mention that in their build thread
Looks like the one for the intake manifold to the brake booster. His engine probably came from a truck with hydroboost which would have just had the plug version of that fitting.
oh worked out cool..i transferred the plugs from the old harness to the new one. however on the neutral safety switch there are about 3 or 4 wires that dont connect to anything. ill take a pic tommorow but i know one is for vss but not sure about the other ones. Also i have a buddy who just put a 6.0 in an impala ss and he didnt use that plug on the driver side of the trans. not sure how tho..Quote:

so now i got the right motor mounts i was able to bolt up the drivetrain. ended up pulling the motor back out so i could modify the factor harness. also wired up the engine. my new harness doesnt have a plug for the knock sensor in the oil pan. is that bad? also i broke my timig cover when i trying to align the engine. and also a coil. if anyone has a coil and timing cover for sale please let me kno!

That sensor in the oil pan isn't a knock sensor it is for oil level. You don't need it.
oh ok...question for ya...i was looking through http://lt1swap.com/1996_vortec_5.7/index.htm trying to figure out what wires i need to take from the old pcm and connect to the new one. so far this is what ive gathered.Quote:

4 vss output splice green wire from harness onto this so i have the signal for the new pcm and still have functional speedometer gauge
5 connect to mil control on new harness for check engine light
10 connect to tcc wire on harness
blue connector
10 tcc connect to tcc on harness
then i believe all thats left would be the tach signal..not sure how to find that wire and im not sure which wore connects to the tcc.
just looking at the schematics this is what i think i will have to do. correct me if im wrong.
moving right along, looks good!!!! wish i could help you out on the wiring. i haven't got that far on mine yet & i'm running only the LS1 ECU. i still have to figure which wires to tie into for the speedo & tach.
thanks man! its a slow steady project. yea i dont think it will be that difficult. im just checking with pitch black because he is very knowledgeable and has helped me out so much during this build. once i get everything working ill will definitely pass the info along.Quote:

The tach will use the output from the PCM as well. The tune can be adjusted to work with the 96 tach which is looking for a 8 cyl output rather than the 4 cyl output the 99-up gagues want to see.
If your harness doesn't have PCM outputs for those 2 things, you will want to add them.
ok cool...any idea what pin that would be from the harness? everything else was right?Quote:
