Any successful 4th gen LS1 dash (w/cluster) swaps??
In order to install the f-body cluster you do not necessarily have to have the complete vehicle harness. The cluster has 12v ign, cons power, ground, illumination, vss signal, oil pressure signal, mil lamp,tach signal, the volt fuel and the idiot lights are serial data. So if you provided those basic inputs to a cluster that you hardwire in and tie the serial data wire into the databus then it would all work. The only PITA would be the fuel gauge bc you will have to use the f-body sending unit in order for the pcm to interpret the fuel level signal and control the gauge correctly. So yes it would be a lot of work but it can be done and is possible without the complete interior harness.
I’m swapping a 2000 TA LS1 w/T56 into a third gen Camaro. I’ve searched and know it can be done but there’s not too much info, at least not for the 98+ gauge cluster. I had my harness reworked for stand alone (removed VATS, TCS, ABS, EGR, etc.) and I’m left with the following wires going to the dash:
Tach (White) from C105 plug, Pin G
VSS Signal (Green.White) from 220 plug, Pin A
Water Temp (?) from Water temp Sensor
Oil Pressure (Tan) from 220 plug, Pin K
SES Light (Brown/White) from C230 plug, Pin B
Voltmeter (brown) spliced straight from alternator plug
Fuel Level (purple) coming straight from fuel sender.
Can anyone help with a diagram for the gauge cluster plug or give me some advice?

[QUOTE=TPI TERROR;9525119]Thanks, now i just need the 83 Camaro cluster diagram. Hopefully I can get everything to work. Did u get ur fuel level gauge to work?
no. i havent tried to because it reads like 70 -240 ohm and i have an auto meter 0-90 to work with my tank already.

Success!!!
Finally was able to get my instrument cluster to operate via the serial data wire. All the gauges are working except the fuel level which I'm still working on. I took my 3rd gen cluster diagrams and hooked them up to the cluster along with the serial data wire from the LS1 PCM as follows:
3rd gen connectors that go to cluster
Incorporated to 4th gen cluster pin outs as follows:
A3 PNK 39 Ignition Power...to 3rd gen Clear Connenctor #2 or #6 Pnk w/Black
A5 TAN/WHT...to 3rd gen Clear Connenctor #7 Brake Reservoir Sensor
A8 BRN/WHT 419 SES light to
A10 ORN 640 Constant Battery 12v
A12LT BLU 14 Left Turn Signal Lamps...to 3rd Gen Black Connector #8
A13 PPL/WHT 237 Instrument Panel Lamp Control ??????
A17 LT GRN 11 Headlamp High Beam... to 3rd Gen Black Connector #10
B1 BRN 9 Park Lamp Supply Voltage...Power w/parking lights
B3 GRY 728 Security Indicator Control (Not used)
B5 PPL/WHT 1035 Starter Coil Supply Voltage...Hot in start, yellow wire from Ign, Switch
B6 GRY 1036 IPC Class 2 Serial Data...from LS1 PCM
B7 ORN/BLK737 Trunk Lamp Control (Not used)
B8 DK GRN/WHT 817 VSS Signal..from LS1 PCM
B9 GRY 8 Instrument Panel Lamp Supply Voltage ??? Lamps form Dimmer
B10 DK BLU 15 Right Turn Signal Lamps...to 3rd gen Clear Connenctor #12
B11 BLK 650 Ground....to 3rd gen Clear Connenctor #9 or or Black Connector #10
B14 TAN 31 Oil Pressure Indicator Control...from LS1 oil sending unit
B15 BLK 650 Ground... to 3rd gen Clear Connenctor #9 or Black Connector #10
now for the pics.

Your not going to get the fuel levl to work correctly for two reasons.
First it also gets to the cluster via the PCM through the serial wire.
Second the fuel level sending unit in the 98+ LS1 cars has a 70-240ohm range verses the tradidtional 0-90ohm range of the 93-97 cars.
Only way to make it work would be to drop the tank and try to mount up the newer sending unit. Then you would have to reroute the sending unit wire to run to the PCM.
Good luck

Come to think of it, i could have even got EVAP to work (if I hadn't removed it) since it uses the tank pressure sensor which I could have easily hooked up by running the positive feed to the PCM (Dark Green) and the ground (Grey wire, fuel level sending unit and fuel tank pressure sensor use the same ground to the PCM). Then i would just have to hook up the Evap Vent valve Control and the PCM would use fuel level, tank pressure to calculate the venting cycles?
Blue (230) Plug
A GRY PCM 46 5V Feed (Fuel tank pressure)
B Brown w/Stripe PCM 25 MIL Lamp Control
C WHT PCM 45 EVAP Canister Vent Valve Control
E Blue PCM 55 Theft Deterrent Fuel Enable
F DK GRN/WHT PCM 17 A/C Request
G GRY PCM 23 Fuel Level/Pressure Ground.
H DK GRN PCM 64 Fuel Tank Pressure
J PPL PCM 54 Fuel Level Input
K DK GRN PCM 58 Serial Data (Class 2)

I hope someone still keeps an eye on this posting... it sounds like you guys have a handle on the cluster wiring. I'm putting an 2001 LS1 in a 69 camaro and have all the wiring taken care of except I'd still like to use my check engine light (MIL Control) and I have an open light spot in my 69 cluster. I just need to know if the feed from the PCM (wire from one of the C220 plugs) is a hot or a ground (since all my wiring is being done before i install the engine and can't use a test light)

back from the dead.
trying to figure out if using the LS1 pcm with LS1 cluster and LS1 tank will result in a working fuel gauge and evap. any what needs to be done to get it to work.

not sure about the newer body trucks, or if the sending unit is even the same, but that might be your easiest route if newer body trucks also use the higher ohm rating.
not much tech from me, but at least some ideas to think about.
