'04 5.3L in a '01 V6 Camaro.

I get it Chris, you know if you need anything I would be happy to help. Did that guy from Ft Worth ever get in touch with you about his truck and LSx install?

Ill be watching, this wont take you long I am sure.

I had one I bought from a guy already converted. 1994 with a LQ4/T56 installed and barely running. I parted it out after having a bit of fun with it, chassis was rusted and wrecked, and his harness was downright scary. If I remember right, you also need a 98-02 V8 steering rack as well. Otherwise looks like you are on the right track.

Thanks John, It will be a little bit, I need to do it on the lift at work....That will take some scheduling!

There is a "performance ratio" Rack, And a "standard ratio" Rack. Nothing that prevents me from installing the engine.

Clean 4th gen F-bodies that have not been wreaked are HARD to find...The only reason I bought this one.

I'm sure you are also aware you need the tailhousing for the trans to bolt the torque arm to?

I am aware, My car being an '01, The 245mm 4L60E tailhousing that it has now will bolt right up to my 300mm 4L60E.

I have been researching how to get the Cluster to work, There is so much misinformation on the internet.

My '04 Blue/Green PCM will not control the '01 cluster, Though some mention segment swaps....No follow through on threads I have found.

'99 & up clusters use Serial Data for every gauge besides the Speedometer & Volt gauge.


'98 F-bodies have full analog gauges.

4000 ppm from the PCM for the speedo.
Tach output from the PCM for the Tach.
Oil pressure sensor wired direct to the cluster.
3-wire coolant temp sensor, Has 2 functions, Temp reading to the PCM, And a feed directly to the Cluster.
Volt gauge reads off the ignition voltage to the cluster.

The problem is...How to get the Fuel Gauge to work? The '98 fuel gauge resistor is wired to the PCM, It buffers the signal & sends it on a dedicated circuit to the Cluster.

I have a '98 Trans Am 160mph cluster, This is the research I did....

Fuel Sender OHM's

According to a GM TSB...
'98 Camaro V6 & V8 250-40 ohms
'98 Firebird V8 250-40 ohms
'98 Firebird V6 40-250 ohms

According to AllDataPro
All '99-'02 F-bodies 40-250 ohms

Great, The resistance is backwards. I decided to do a working model. Because I don't trust the info.....

'97-'98 PCM (GM racing, version 1) It has the same service number as a '98 V8 F-body, wired the grounds, Ignition hots, battery hots, & Data link connector.
Powered up the Cluster Ign., B+, & grounds
Wired the fuel gauge output to the cluster.
Used some resistors from Radio Shack to simulate a Fuel Sender.

66.9 ohms, Fuel gauge reads just above empty or 10%

147.3 ohm, Fuel gauge reads half or 45%

214 ohms, Fuel gauge reads almost full or 83%

Either the Ohm range info for a '98 T/A is wrong, Or this "GM Racing" PCM has a non-F-body base tune. I check the VIN with my Tech 2 & it read GM**RACING**VERSION**1......That was weird.
Also double checked the fuel sender that is in the car now, Gauge reads 1/4 tank & the Sender resistance is 123.3 ohms, So it does have a 40-240 sender.

If I use this set-up, The '98 PCM will only work the gas gauge.....I have to find a place to mount it, wire it, & re-pin the cluster plug. I will call it the Fuel Gauge Module

It would be great to make the Truck PCM run the "Serial Data" cluster.
I have access a '00 T/A 0411 PCM for the needed gauge segment.
Any insight on this?

Pics, I was using a 18V dewalt battery, The volt gauge is reading a little high.....

I wouldn't go with the 98 PCM, specific to the 98 Harness and there are other reasons.

Why not use a 1220411 ECU, with an f-body harness and convert to cable throttle? 411 are easy to find in the boneyards for about any 99-02 truck/suv/van applications.

^^As I stated, The '98 PCM will only control the fuel gauge. It's locked anyway.

Going to use the '04 "Blue/Green" truck PCM & drive by wire for now for a couple reasons....

My LS2 intake does not have provisions for a throttle cable bracket. I am not about to pay what people want for LS1/LS6 intakes.
'01 V6 Camaros are already drive by wire, No hole in the firewall for the cable.
