digital dash

[beretta]

well i have been looking for some time now for a wire harness for a digital cluster and havent had much luck, the car i took it out of i never took the harness as i never had plans of using it, i figured i would sell it later on but now i want to use it.

Im going to make my own harness for the cluster and hopefully wire it into my existing harness. i do believe i have the ecm from the car i took the cluster from, i know 1 of them i had worked my spedo and 1 didnt. so its prob the one that didnt since it works the digital part not analog.

im wondering if my current ecm will handle the digital cluster without problems. not sure if the fuel millage meter and stuff like that is part of the ecm itself or programed in the ecm, so that function might not work for now be real nice if it did though.

Anyone else tryed to do this and have good luck before ??

heres the start of it, looks like it will be an all day project lol. im pretty positive i have wire schematics for both analog and digital cluster and for 4 cylinder dash harness and v6 dash harness so hopefully i can figure out the wiring and it should be pretty simple..
wires from a computer power supply main board power connector, hacked apart needs to be trimmed up but they fit snug on the connectors in the cluster and have plastic around them so they wont short out.

well think i found what i need to know here. shows the wire colour and what it does, but not where its located on the plug ..

ok had a better look at it, the connector is labeled and numbered, so i have everything written down now and im off to see what i can do with it now. wish me luck lol

[beretta]

what a nightmare LOL, fighting with wires all afternoon, finally got the cluster finished, now i need to figure out the wiring on my car be nice if i could bare the ends of the wires and maybe push them into the existing plug so i dont have to cut anything.

2 rows of 16 on the cluster. what alot of wires for something so simple LOL

[beretta]

Im stuck... LOL need help on wiring for my dash, the book shows different then what my wires are, i figure out what like 4 of them are thats it and its different in my diagram..

my car is a 88 base 4 cylinder dash harness...

Anyone have a wire diagram for analog cluster in a 88 base 4 cylinder ??

Z Y X W V U ..... T S R Q P O N
A B C D E F ..... G H I J K L M

thats how my plug is numbered looking at the connector end.

Z Pink ?
Y N/A
X N/A
W - WHT (TACH ?)
V -ORANGE ?
U - GREEN/WHT

T - ILLUMINATION/ GREY
S- BLACK ? (GROUND?)
R - N/A
Q - N/A
P- ORANGE/BLACK ?? (HAS POWER WITH KEY)
O- BLACK (GROUND??)
N- PINK/BLACK... (POWER WITH KEY)

A- DRK GREEN ?
B- BROWN/GREEN ?
C- BROWN ?
D- LIGHT GREEN ?
E - BROWN/WHT ?
F - N/A

G-LIGHT BLUE - TURN SIGNAL
H - YELLOW ??
I-GREY/BLACK ?
J- DARK BLUE - TURN SIGNAL
K-PINK/WHITE ?
L-GREY/BLACK ?
M-BLACK/WHT ?

copy and past and remove ? and replace with what it does if you know any of these LOL. cant find nothing for a diagram online maybe someone has access to a shop with Mitchell on demand ?

[beretta]

no one has a service manual for a 88 with diagrams ???

Update.....

took a few hours to get it all wired up.. i just pulled the wires from the connector instead of cutting and taped them until i tested it, so it kind of worked after all of that LOL.

everything worked except for.. Eng Temp. Tach. Spedo, Oil pressure, Amperage ALT.

It lights up and looks cool LOL the ALT might have been a power wire in the wrong spot, but it Illuminated with the dimmer so that worked. not sure why the tach and spedo didnt work i think i need the complete harness because a couple things are different.

So i now have the analog dash back in for now.

Your tach, temp and volts are done through serial data. Your analog harness didn't have that line running to the ECM. You can tap off that wire at the ALDL.

HMMMMMMMMM.... LOL

D2 - (ORN) Serial Data input (from ORN wire @ ALDL)

But thats 1 wire.. how does this run, tach/ eng temp from 1 single wire.

There was a solid orange wire on my connector and i had that hooked up to D2 on the digital cluster. the Spedo didnt work though it just reads 0. i had the spedo wire hooked to the correct wire on my connector.

Well... i didnt cut any wires on the car, i simply pulled them out of the connector and taped them, so i eneded up putting the analog cluster back in for now. took me all frigen day to get this done what a mess of wires hahaha. but it kind of worked and at least i didnt fry anything.

My ALT voltage didnt read either, might have had a power wire on the wrong spot as there is 3 wires in my connector that have power when key is turned on. also the digital cluster calls for 2 wires to be live all the time,
C16 - (ORN/DK BLU) Constant power (Hot at all times)
C15 - (ORN/DK BLU) Constant power (Hot at all times)
i hooked these into a live wire with the key. cluster only lights up when my parking lights are on, i think it should light up in the day too other wise you cant see nothing lol

The digital cluster wire diagram does not even show where the tach imput would go, along with eng temp AND alt voltage, how does this work off 1 wire i dont understand. so if i hook that orange wire up the the data port all that will work. ? my oil pressure wasnt reading either but it hooks to TAN and there is like TAN and light brown kind of look the same, but maybe without the orange hooked to the data port it wont read that either ?


.... Fuel gauge worked, turn signals worked, lights up with parking lights on and dimmer works. changes between settings with the button for mph.kph. odo trip ect. was either my oil pressure or engine temp was all the was to the top and flashing forget witch one it was now. only thing that worked proper was the fuel gauge on the bottom left of the panel. so it kind of worked at least.

So maybe ill tare it apart again tomorrow, wire it all back up, should not take as long with daylight, in the dark really sucks lol. if it does work, then i have to figure out how to get my mess of wires in the small area that there is behind the cluster or its not going to fit into my dash lol.

[Cliff8928]

The tach/volts/temp are via serial data. They're digital, not analog signals.

[beretta]

so they will all work once i hook up the 1 wire ?

any idea why the cluster only lights up with parking lights on ?

[Cliff8928]

There's a relay that is in a digital car that keeps the lights on during the day.

Well would be nice if i can hook it up to come on automatically with the key. i have a full wire schematic for the digital cluster, shows where all the wires run to, if i follow the 1 that goes to the relay im sure i can figure it out.

I knew about the orange wire going to the serial port, but there was an orange wire in my harness i thought was that wire, wish i left it hooked up so i could try running 1 wire for that LOL, now i have to do that all over again and wire everything else back up. FUN FUN. at least i can learn as i go, im not a pro at wiring stuff but i know the basics and how to look at a diagram.

And without a connector for the cluster i figured out a way to connect wires to it so it can be wired up.

[beretta]

C16 - (ORN/DK BLU) Constant power (Hot at all times)
C15 - (ORN/DK BLU) Constant power (Hot at all times)

These to wires should be hooked to hot wire thats live all the time ? or will it work with key on power ?

[beretta]

ok i got it all hooked back up again. still the tach is not working...

Spedo works, high beam indicator works, turn signals work, service engine light works, fasten seat belts works. few other things prob work i didnt mention.

Not working.. Oil pressure just flashes full bars, engine temp - this might not work anyways it read over the top on my other cluster (fan relay is tripped to stay on all the time so no worries) Amperage Alternator and No tach.

I would really like to leave it hooked up this time and get everything functional, at least the spedo works thats the main thing, the rest wont stop me from being able to drive but would be nice if they worked.

I have the orange D2 hooked to the orange on my data connector.. how can i test this wire to see if its even working, maybe its a problem with that wire to the ecm. maybe its my ecm all together, maybe ill try the other 1 have from the beretta that had this cluster in it. i have 2 ecm's both ran my car but only 1 worked my spedo, so maybe the one that didnt work my spedo was from the digital cluster car...

Please help LOL, would really like to put things back together so i can drive the car.
