Up under the dash there are 2 nuts that need to come off. They are JUST past where the column goes past the plastic of the dash, and very easy to see. Did you get those yet?

Re: Blakes LSx swap - pic/vid heavy
Huh? Wiring, 3 firewall bolts, two nuts on the chassis, and removing the intermediate shaft... It comes right out.
Doors off to make it easier???
Oh wait...Blake did you take the intermediate shaft off of the column all together? It should be out. Then there is only like 4-5 inches of column on the outside side of the firewall.

On the far left side of this pic, you can see the bottom of the column. Thats all that should be left after removing the intermediate shaft. Piece of cake from there...

Re: Blakes LSx swap - pic/vid heavy

Re: Blakes LSx swap - pic/vid heavy
Haha you didnt sound dumb dude. I wasnt sure if we were all on the same page or not because I read something about the doors being off. Just for future ref...the column comes out easy peazy with the doors and seats in.
Just gotta make sure its all disconnected and have that intermediate shaft removed completely.
Hardest part in my opinion is getting all the wiring and stuff back in exactly as it came out haha. I always get to that part, and say "I shoudl take a pic of how the wires are routed so I can route them again....nah Ill remember this time". And I always end up having to screw with it.

Technically you dont need it anymore, but if you run across a manual column itll have a lock suitable for a T56

Re: Blakes LSx swap - pic/vid heavy
I cut my lock cable off with a pair of dykes. It's only used for an automatic transmission so if your going with a T56, it serves no purpose at all. I would def remove it or cut it at the column.

Re: Blakes LSx swap - pic/vid heavy
The purpose of the lock is to prevent you from taking the trans out of park unless the key is on for a measure of safety and security. The second purpose is when you have trouble while driving and must shut the engine off but need to retain steering to safely stop. It prevents the key from being turned to lock until the shifter returns to park. Manual cars have a tab or button doing the same thing. These do not affect being able to drive the car in the least, so you technically dont need a lock

Re: Blakes LSx swap - pic/vid heavy
you could do some sort of dual post type deal and have the positive and negative break off seperateyl through a whole in thetrunk area beneath the car and cap them off so when your battery dies, you uncap them from under the trunk of the car and then jump it. are you going to shave the lock on the trunk too. because i thought those just open with a key and are hidden behind the liscense plate. so id keep it that way

Re: Blakes LSx swap - pic/vid heavy
Wait why couldnt you just use the key and open the hatch? The pull down is the only electric part. It still has a manual latch that will pop with the key. When you apply power, the pull down should move up into position ready to snag the hatch when you close it.

Yellow goes to your dimmer switch. Without it, you get no headlights at all. Only firebirds had a headlight module to control the door motors

Id suggest bookmarking the ATGO site and paying close attention to the misc exterior diagrams. The fuseblock/engine wiring you're changing. Lighting stays the same

Re: Blakes LSx swap - pic/vid heavy
I'll have to double check mine, but if I remember right, I thought red was constant hot (direct to battery), Orange was key on power, yellow is headlight low beam power to dimmer switch, and green was for high beams, also to dimmer switch. But like I said, I'll double check if you'd like. And also keep those wiring diagrans that pocket posted in mind. I've used Austin 3rd gen A LOT to wire my car with those diagrams. They are very helpful.

Re: Blakes LSx swap - pic/vid heavy
I pulled the tank to mock up the new fuel lines (came out nice). I have a similar question about wiring the pump. EVAP will be deleted, and I am using a program-able fuel gauge. Can I just use the fuel gauge, pump power and ground wire and splice them into the 3rdgen 3 pin connector?
What are all the other wires for??
anyone???

Plus I think the fuel level sending unit might need a proper ground on it's own wire in order to relay accurate info to the gauge. Again, not 100% sure on that though.

"Wiring change, cut the 3rd gen pigtail as close to the sender as possible where it goes into the tank, 3 pins. Locate the 4th gen pigtail where it goes into the sender and cut a few inches free. There are 6 pins, 4 are reused
4th gen pigtail, 6 pin
Pin B is fuel pump 12v, splice this direct from the 3rd gen harness gry to gry
Pins C blk and D blk/wht are grds for the pump and sender respectively. Splice these to the 3rd gen grd wire blk
Pin A ppl is fuel level sender signal. Splice this to the last wire on the 3rd gen pigtail ppl to ppl
Pop the new sender in, splice 4 wires, done
Harness still functions like before"
4th gen pigtail, 6 pin
Pin B is fuel pump 12v, splice this direct from the 3rd gen harness gry to gry
Pins C blk and D blk/wht are grds for the pump and sender respectively. Splice these to the 3rd gen grd wire blk
Pin A ppl is fuel level sender signal. Splice this to the last wire on the 3rd gen pigtail ppl to ppl
Pop the new sender in, splice 4 wires, done
Harness still functions like before"
My 4th gen fuel pump connector consisted of:
3A PPL Fuel gauge sensor signal
3B GRY Fuel pump motor feed
3C BLK Ground
3D GRY/BLK Reference voltage feed-5 volt reference
3E
3F BLK/WHT Fuel gauge sensor ground
3G ORN/BLK Manifold absolute pressure sensor return
3H DK GRY Fuel tank pressure sensor signal

If you're using a programmable fuel gauge, why did you change out the stock 240-33 ohm sending unit? I'm using a 4th gen LS1 plastic tank with the stock sending unit (and stock pump, btw), programmable gauge, it works fine with the 240-33 ohm sending unit.

Re: Blakes LSx swap - pic/vid heavy
Ditto..I never cracked my tank open. Tried to get a non-programmable to work. IN the end, I wish I just went with the programmable one from the start. Works great! Best part is, I can program in my "cushion" for needing gas. In other words, I program it so when the gauge is hard on E, I still have like 4 gallons left. Gets me to the gas station on more than fumes haha.
Glad to see you're still plugging away at it Blake! Fuel lines are looking great. Thats what I hope to do when/if I ever get to work on my car again. Black -an and stainless lines. Im jealous of that CA weather right now...even if i had time/money to work on my car it would be too cold haha.
