Do you mean switching the entire gage cluster out? I bought a non-SR5
4Runner last summer and traded the whole gage cluster from my SR5 truck,
(both are 85's) with no wiring change. The only change I made was to swap
the oil pressure sensor from an idiot light sensor to a gage sensor.
The truck dash even had the right lights for the back door of the 4Runner.

I performed this swap (instrument cluster) on my '83 and I had to
"re-pin" the connectors so everything hooked-up correctly (the new
cluster was out of a '83 SR5). If you have a copy of the schematic it
is not too tough, all the wire colors are the same. My instrument
cluster still had the original plugs with wire ends in them, making it
even easier. To connect the tach I ran a wire through the firewall into
the plug near the coil. Everything works great! Only thing I have left
to do is set-up the oil pressure/volt gauges I also picked-up. Anyone
know the average price of a 22R oil pressure sending unit?

He is right, the 83 SR5 gauges use the same connectors, but the pinouts are
quite different. After I finally bought a set yesterday, I decided I needed
to hook them up immediately. I was up late, but they work and look great
today. I also swapped the light bulbs from my old idiot lights (still in
good shape) into the panel illumination sockets on the new panel, and it
looks nice and bright. The two differenes between non-SR5 and SR5 basic
panel is the addition of a tach, and a resettable trip odometer. The layout
is nicer, and after cleaning the inside of the plastic cover and replacing
the bilbs, it looks like a new truck.
After figuring out the pinout mods, it took a while to figure out how to
pull the pins out of the connectors. The secret is to jamb a small
screwdriver between the back of the pin and the plastic connector shell.
There is a little one-way hook in there that keeps the pin in the shell.
Push down the hook, and the pin can be pulled out with the wire and be
reinserted into the new location.
There are three connectors which are keyed and cannot be swapped around.
The circuit connections are numbered on the flex circuit on the back of
the gauge panel. Each connector has 8 pins. Blue connector is pins 1-8,
gray is 9-16, and the white is 17-24.
The tach input wire is not available in the harness. I didn't have any
spare pins, so I ran a wire from a ring lug fastened to the screw on the
tach input connection to the yellow wire from the igniter in the engine
compartment. There is a wire connected to that point on the igniter
running to the CA smog computer, so I spliced another wire for the
tach into the truck side of the harness. (So I can easily swap my friend
the igniter if required.)
For the record, here are the pinout of SR5 vs non-SR5 gauge for 83:

3 3 BR (B BR) Speed sensor (-) ground
4 6 GL Speed sensor (+)

that's what I found out... I paid $45 (US) for mine, plus $21 for a new oil
pressure sender. It's a 10 minute deal... un-screw the 5 screws holding the
dash, un-do the 4 that hold the cluster, un-hook cable/wires, and put back in
in reverse order. Go underhood and swap the oil pressure sender, and you're
done.... It took me 20 minutes, because I cleaned everything real good before
I re-assembled it.

You may not need to do this. On my '87 deluxe 4runner, the low fuel
light still works, even with the new SR5 gauges (I believe mine came out
of an '85 4runner, but any model, probably even a 2wd p/u will work.
The only real differences I've seen, is that some don't have the blank
for the low fuel light or little things like that. The older ones also
only have a 85 mph speedo that looks a little dated IMHO)
The other thing you *may* need to do is add a wire for the tachometer.
I believe all EFI trucks have this, and I bet probably all the older
pre-efi engines ('84 and older I guess) probably have this wire.. but my
friend's '86 deluxe (4wd carbed, wing windows, PS and that's it) didn't.
What you need to do (and this is real easy) is to run a wire from the
tachometer 'check' deal that runs off the coil to the #6 spot on
terminal A. For clarification, the carbed coils (that I know of) don't
have a 'negative' spot on them, like most other coils, so it's easiest
just to splice into the tachometer tester plug in (it's just a one wire,
capped green or yellow plug hanging off the coil).
If you're wondering where the 'A6' spot is on the back of the guages..
here's what I mean. Turn the gauges upside down, and look at the back,
and you'll see three plug ins (I'm looking at mine as I write this)\. On
the right of the left most one, you'll see a 'circle A' and two numbers,
a 1 at the left to a 12 on the right. You want number 6.
There may be an easier way to splice the tach wire in, but here's what
we did. We used about 16-18 gauge wire, pushed it through the wiring
'plug-in' and then stripped off the last 2" of wire. Next we folded it
back on itself 3 or 4 times until you're left with a 1/3" long clump of
wire. We twisted this over a few times then wedged it back in the
plug-in. Then we just plugged it in and it works. The first time we
only folded it back on itself once. It worked, so we put the whole dash
back together. Then it stopped working. PITA..
Oh yeah, and thanks for the advice on getting the speedo recalibrated.
I may have ruined the speedo in the process (I gotta wonder just how
sensitive that little coiled spring is.. hopefully it's pretty tough ;)
but I managed to pry back one of the clips using a few screwdrivers and
pliers. Then I pulled the wheel/number cluster halfway out, and just
spun it (working form the left to right) until I had the right mileage.
I'm still hoping I didn't screw up my speedo in the proccess though...
oh well, I've still got the original.

Subject: SR5 Gauges/Odometer Adjustment
I'll try to answer both Dan & Jonathan's questions at same time since I just
happened to do the SR5 to non-SR5 cluster swap this past weekend. Here goes :
1) SR5 Gauges :
The SR5 cluster should theoretically go right into a non-SR5 HiLux/4Runner
with little if any add-ons but that really depends on your truck and
configuration. I just swapped a 4Runner SR5 cluster into my non-SR5 4Runner
('89/22RE/5spd) and it took about 1 hour (had trouble disassembling odometer
to adjust mileage). There are 5 screws to undo the dash cover then unplug
the "clutch cancel" wire, 4 screws for the cluster itself. Unclip the 3
electrical plugs, then the speedo cable. Remember to undo the speedo cable
clip behind firewall in engine compartment to give it more slack otherwise
it can be tricky to reconnect. When installing SR5 cluster, reinsert all 3
electrical plugs and turn on your dash light to make sure all the instrument
bulbs are working, if not just swap from your old cluster (I found this out
after finishing the whole thing and had to repeat the process again). I
actually replaced the 3 main green bulbs in the SR5 cluster with untinted
bulbs from my old cluster .... now I have a brighter instrument panel
without that weak green hue.
As for the sensor units, my Runner seemed to already have "voltmeter" & "oil
pressure" but I don't seem to have "tailgate" and "seatbelt" sensors.
2) Odometer Adjustment
On the spindle that forms the axis of the odometer gearwheels, there's a
small black "C" clip beside the leftmost mileage digit wheel (100,000's).
Pull this clip out carefully. Now you can 'unstack' each and every digit
wheel and uncoupling them with the in-between spacer disks by shifting them
to left along the spindle. Turn each digit wheel independently to your
current mileage (some evil thoughts may pop up at this time .... resist the
temptation!) Re-insert the "C" clip on the odometer spindle and reassemble
everything in reverse order.
Good luck and let me know how it goes.

The drill route works Im sure, but with a little patience and a pair of
needle nose pliers you can set the desired mileage in a couple of
minutes. Just pull out the metal rod that slides thru the brackets on
each number roll...its a press fit...be careful not to bend it too bad.
Then set the desired mileage...if you push the number towards the front
of the cluster..the bracket will hit....just keep easing on the number
and it will slide thru the bracket....Get the right mileage...line up
all the small black brackets and then slide the pin back in.....Only
took me about ten minutes.
Oh by the way....you don't have to change the fuel gauge sender unless
you want the low fuel light..that is the only difference.....
