Warning lights to 91 cluster
I am putting a 6.0 in my m1009 and it has the warning lights. I have a cluster from a 91 suburban that I saved and I think I have the module for the speedometer to work. I am swapping to a 241 tcase so I will have vss. Has anyone ever swapped out the warning light cluster to a gauge cluster. I did this in my 67 but I am not sure if it will be the same.
Thanks!!!! |

Re: Warning lights to 91 cluster
I'm not there yet but doing it real soon. I just swapped 6.2s and plan to use the gauge cluster from the donor truck. If it does not plug n play I plan to swap dash harnesses too.

Re: Warning lights to 91 cluster
You should be fine as long as you use the correct senders for the gauges.

Re: Warning lights to 91 cluster
Do you think I could do it too. The 6.2 has the gauge senders including the wiring harness. I was hoping I could also just swap clusters.

Re: Warning lights to 91 cluster
Buying the senders will be cheaper than a set of aftermarket gauges too I am going to get on steelsoliders and see if anyone has done it. I did a search on here but I am still not sure if the pinouts are the same.

Re: Warning lights to 91 cluster
That was my thought and why I'm prepared to swap dash wiring too.

Re: Warning lights to 91 cluster
I guess I answered my own question or a guy on steelsoliders did....lol
Here is a breakdown of how to wire in a civilian dash board / gauge cluster with oil, temp and two volt gauges. First identifying the wires: 2 brown wires- Gen 1 & 2 Gray- Low coolant Pink & black Hot from fuse box Tan&white- Brake warning Tan- oil Black- Ground Brown&red- Gen 2 relay Dk. Green- Water Temp White- 4WD light Tan- Dash lights Orange_ Hot, 24Volt, power feed for 2nd volt gauge, and/or 2nd gen. light. Dk. Blue- Right Turn Lt. Blue_ Left Turn Yellow_ Seat belt light Here's where to move them to in the dashboard / gauge cluster connector, by the numbers on the connector. 1. Hi beam 2. Dash Lights 3. 12 Volt gauge ground 4. 12 Volt gauge input, (should be only when switch is on). 5. Oil sender wire. 6. Positive / Hot 7. clock, leave empty if don't have a clock. 8. Clock also. 9. Temp sensor switch. 10. Positive / Hot 11. Right turn signal 12. Left turn signal 13. warning / dummy light ground 14. Warning / dummy light ground 15. Warning / dummy light ground 16. Positive / Hot 17. Warning / dummy light ground 18. Fuel sender wire. #'s 1, 2, 11, & 12 stay the same as they were, some others may also, I don't recall. If your truck your taking your donor gauges from was 4wd, it will have a 4wd. indicator in position for # 15, low cool will go in # 14, and brake into # 17. To wire in a voltage gauge for the 24 volt battery, take voltage into the voltage gauge from the 24volt bus bar, and ground it out from the gauge to a 12 volt positive point. The reading will be high, but within the scale of the gauge. To position the gauge in the factory gauge position for the clock takes some work. I found a factory gauge face that fit across the opening. I removed the gauge working parts on it and installed the gauge working parts from a voltage gauge to that face with silicone. I used a white after market gauge face to match the other gauges. I then reattached the needle to indicate the correct position at zero power. If using a factory voltage gauge for the donor parts gauge, you need to solder a wire to the correct metal post, and use a nut to hold the other wire to the correct aluminum post. If you look at the factory gauge in the cluster you will see which ones to attach the wire to. You will also need to do some cutting. Remove the area behind where the gauge will go to allow the wires to come through. Also remove the covered area where the clock would have gone. I used a cutter in a Dremel tool for this and it came out neatly done. Hope this helps someone save a couple days figuring this out like I just spent. Edits: You will need new sending units for the two gauges, oil and temp. You can put indicator lights for the two generator wires in some where else and run extensions off the two brown and brown / red generator wires to them, thus still having the two dummy lights. Wiring the Generator dummy lights: #1 Gen. light. Feed it 12volts, and ground it to the brown generator wire. #2 Gen. light. Feed it 24volts and ground it to the brown/red wire that goes to the Generator #2 relay. This relay should be powered on whenever the key is on. It is located below the stock radio opening, near the diagnostic plug. There are two regular relays there, the #2 generator relay and the original voltage gauge relay. There will also be a heavy duty relay, this is the starting relay. |

Re: Warning lights to 91 cluster
Let me know how yours goes in the event you are done before me and I'll do the same. Only difference I'm eliminating the second Alt and going entirely 12v on the starting system.

Re: Warning lights to 91 cluster
Love the lift and Hummer wheels - not many have two sets either.
How much lift to clear the 37 Wrangler Radials? I plan a 5.3 or 6.0 in the future but have not decided if it will be in the CUCV or my V3500 (former USAF Crew)

Re: Warning lights to 91 cluster
That is just 5" under it and there is plent of room for them.... they only measure 36" tall. I would love to have a crew!!!!! Put a GENIII in both of them, should only cost about 8K

Re: Warning lights to 91 cluster
What wheel spacers did you use to get the hummer wheels to work?

Re: Warning lights to 91 cluster
I got them off ebay, they are 2" and I can't remember which brand they are. 2" is what you will need. That was a good looking ol' k5!!

Re: Warning lights to 91 cluster
Thanks, 3" body - 6" Skyjacker lifts - 40" Gumbo Monster Mudders, Freshly rebuilt 4bolt 355/350/203 but my drawback - 3.08s
Loved the truck and really miss it today.

Re: Warning lights to 91 cluster
I sat down while watching tv with both clusters and traced the circuits and figured out what is what on both... several wires will have to be swapped around but I figured that. I just wonder about the senders now for oil, temp, and volts ( will I need new pigtails)?

There is a excel ss with the pinouts in that thread... maybe it will help someone else. |

Re: Warning lights to 91 cluster
on my LT1 truck, I put the VSS signal output from the PCM directly to the pin on the cluster. I'm not sure what happened to my notes, but it was really easy. GM used the same colors of wire for years, so that helps when you are repinning the cluster.

Re: Warning lights to 91 cluster
I just wish I knew what pin it was or had the plug from the 91 that I hauled to scrap that I could have used the gas tank from as well

Re: Warning lights to 91 cluster
Seems like it was in the middle, maybe #13 or #14. On the 91, it actually goes to the DRAC first. THe newer PCM has the DRAC built in. I printed the wiring diagrams off of autozone's website, and traced the wiring from there. They have a wiring diagram for a 91 R/V body, which all have the electric cluster.
