Permission granted to raid '92 dash instruments!

[DeckArtist]

Ok so I got the go ahead to rob the '92 next door of a few things. Most notably the gauge cluster in the dash. Knowing it is going to get grafted into the '89, should I pull the printed circuit behind it as well?

If so, how do I go about doing that and what connectors will I need to save in the process? As you can tell I have never done anything like this. I have read the threads on putting the newer cluster in the older trucks, but since I can get the circuit as well I'm wondering if that makes things much easier or not?

There's only one connector. The whole cluster comes out as one piece. The 92 cluster won't plug in to your 89. It has a different connector. You'll have to do some rewiring to put a 92-94 cluster into a 88-91 truck.

Bummer....thought I had a shortcut. Story of my truck life. No worries though, still getting the cluster tomorrow. I hate the moonies, had them in my '87 S-10 Blazer 4x4.

I love the moonies. As soon as you bury the speedo the other end lifts up.

Got the cluster out in a short order, then the washer bottle transfer to my truck went swimmingly! Had to take a pic of the big block while I was at it.

I have done this conversion to my 89. You need the plug from the donor truck that goes into the cluster. You must also modify your dash to hold the plug. All wires must be spliced , cut off old plug and match up wires, most circuits are the same. It all worked out well in mine and i got a tach.

Cool thanks for the heads up. I need to snag the connector after work, didn't pull that. Is it hard to get out?

It’s part of the wiring harness, so it’s a cut and rewire thing. Each wire is a different color, so it should be almost match for match. However, I haven’t done your particular job, so I don’t know anything about it. I have rewired a 98 cluster to my 94, but I haven’t finished everything in my swap yet to know if I got it 100%.

Yeah I pulled it out as far as I could then snipped each wire. I probably have about 3" behind the plug. When I snip mine I will get it right up next to the plug so I have a few inches of wire to work with. Got an expert mechanic that will be helping and we're going to follow the instructions I found here and on the 67-72 board.

You also need the "DRAC" I believe its called, which is located behind the glove box. Its a white plastic box, sized like a sandwich but a little smaller. The DRAC is what alows the speedometer to work, and also does the speedometer calibration so it reads the correct MPH for your gearing and tire size. Theres a writeup on the web how to do the whole install.
