cheapthrillb2 How about disabling the engine and air bag lights on the factory cluster? W/o taking the cluster apart. 04 LJ.

I have full hyd. Steering so I removed the clock spring and replaced the wheel with a aftermarket w/quick release.

I did the Redline tach swap (which works really well). My good friend that helped with the swap thinks that he may have cut too many wires he's stopping by this Friday afternoon to have a look see.

Hoping to get into Campbell Ent. this week to get the tower made for my Art Carr shifter. That would only leave the AC rework left to be done.

Zero Gravity Transmission did a great job programming the 6L80, including Sport mode, Manual mode (PCS paddle shifters), and 1st, 2nd gears that hold.

aribelin Got the 5V reference figured out, the throttle body didn't finish its initial startup and would kill the engine. Swapped with another L96 throttle body and it purrs like a kitten.

Now the ONLY problem I have is that the oil pressure gauge doesn't work (factory gauge with the factory sending unit placed above the filter in the LS). The rest of the gauges work great. The "check gauges" light is illuminated because the oil pressure doesn't work.

has anyone done the harness them selfs?
what radiators have you had the best luck with
For the radiator aspect of the build I would stay away from Griffin and Advance Adapters. My AA unit failed me after only about 8,000 miles of easy use and I was basically told "tough shit" on it failing (tubes cracked along the tanks). Griffin wanted to charge me $2400 for a radiator.

I went to Novak Conversions and was thrilled that they offered exactly what I needed at a fraction of the cost that Griffin quoted me. They also worked with me and welded on the lower bung at the angle I requested due to my non factory thermostat housing setup. All in all it worked out beautifully and I couldn't be happier. Good down to earth folks over there as well.

For the wiring harness I had mine done by Speartech and have been happy with it. This is before Wayne started to offer his services for wiring harnesses and I'm sure he can take care of your needs as well for your swap.

Sounds like the Jeep regulator is still in the system

Get everything from Advance Adapters or build it yourself. They do lots of swaps and build their own stuff. Very painless.

As someone that does ~15 or so harnesses a week, they are easy. Cut everything out you don't need. Tape it all up. Get a 6 position fuse panel, and connect the pinks to it. Stub out your all time power, tach, etc.

pcoplin Anyone run a flipped Dana300 behind a TH400? It's actually a Stak RAC but the size should be the same.

I already am tight to my 46RE, I'm wondering if a TH400 will be worse?

showjyr I have a Mean Green alternator off my 4.0 and would love to use it.
I'm going to use an alternator relocation bracket to swap my alt to the passenger side anyway and I can make or modify brackets.
I'm not going to be in the shop for a few days to physically look at anything wiring or pulley/belt wise.
Anyone know if it's possible to run the Mean Green? It's the same dimensions and bolts on the same as stock.

Yes, all the grounds are attached but it did go back and put star washers in them too.

Throws a P0641 code every time (low voltage 5V reference 1) and dies in about 15 seconds. I've had the PCM checked and the vendor says that all the 5V's are fine but it wouldn't start again this Saturday. Some of the sensors are showing 3.7 volts when checked with a multi-meter. Battery is sitting at 12.4V's.

Any suggestions?





Good horns finally:



Brought it home from my good friend's house that did a lot of the work (couldn't have done it without him, I helped really ...):



Still a ton of little things to do, but it is good to have it home again!

cheapthrillb2 Alright got my ls swap in and running, tuning almost done. I decided to swap in a 05-06 fuel tank and pump module.

I retained my 04 filler neck.

I do not have anything hooked up to the tank other then the filler neck, breather line off the filler, and the feed line off pump.

The large connector for evap currently not hooked to anything.

This thing takes gas so poorly. Like 5 minutes to feed in 2 gallons. Obviously not venting well.

Any thought? I do not have any of the smog parts/pieces from the 05 and the 04 stuff is different.

#1 is not there, because I dont have the line where it connects at #2
#3 is hooked to filler neck

Torque app now has Oil Pressure PID!!! - Page 3 - LS1GTO.com Forums

PID: 22115c
Min Value: 0
Max Value: 100 # This puts the needle at 12 o'clock at 50 psi
Scale: x1
Unit: psi
Equation: (A*0.65)-17.5
OBD Header: Auto

His adjustment factor to zero the value was 17.5 Mine seems to be closer to 18.5

If anyone is going to be at KOH that has a scan tool that shows oil pressure, it would be awesome to verify this value! PM/Email me.
Anyone else try this on torque app yet? Mine worked but im showing low (4-5psi at idle) oil pressure and am going to verify with a mechanical gauge this afternoon.

cheapthrillb2 Thoughts on 4L65E RANGE Sensor connector pins 9-10-11-12

It starts and computer sees each gear as I run through selector.

Looks like 10 is just reverse lights.

9-11-12 for starting when in park/neutral?

EDIT: One thing you would have learned if you read the thread - There is nothing painless about using Painless. They suck, M'Kay...
I just looked back through everything and I guess it's wired for both...I just need to figure out what to use when I get back in the shop and can physically look at it.

This is the only issue I've had with the harness and it's nothing to do with them just the setup I'm using. Why do you say they suck? Everything else is where it should be and pretty simple.

This thread is 591 pages and nearly 6000 posts...I started reading through but it's redundant and there's so many options a lot doesn't apply...not to mention conflicting info.
