Bump to a 4 year old topic! Just used this to re-pin my gauge cluster. 90/91 Dx/Si cluster into an 88 Hf.

I practiced de-pinning and re-pinning on a spare dash harness I have from an 88 Dx. It doesn't have the little blue plug in the center of the cluster, although my 88 Hf does. Either way I've tested both harness being pinned for 90/91 clusters and it didn't seem to make any difference whatsoever.

The only issue I have is with the lighting. Everything corresponds to the diagram but I'm not getting any backlights. The 88/89 dimmer switch is the same (function and wiring) as the the 90/91, so I know I have a good switch, as I've used both during testing. Anyone have this issue?

*Edit- Figured it out, most of the bulbs in my new cluster were burned out/missing. Works perfectly :-)b

Great timing for this. I am building a new face panel for Autometer gauges and want to relocate some of the idiot lights to an led strip. Thanks for the wiring diagram. :-)b

This is old but whatever.

I'm sure this isn't 100% correct about the 88-89 colors and wire locations.

I tried to do this the other day and found out I had 18 wires instead of the 19 pictured. This was on an 88 Si. I checked my dad's Stock 88 DX and it was exactly the same. Both were missing a wire. Non were modified.

88 clusters don't have the door icon on the clusters either so I think that might be a problem? Don't know yet since I'm still trying to mount it.....(I got the wiring done though)

And that's another thing! The 90-91 cluster does not mount up to the 88 dash board bracket things that hold it. You have to modify the brackets because the cluster leans forward.The upper part needs to be modified so it can lay back abit.

You can't just get the 90-91 brackets either because then the cluster sits higher and then you can't put the cluster surround on it. :shock:

and yes I have both of the brackets.

Well I got my 90-91 cluster in the other day, but the door icon didn't light up like I predicted! :?

My 88 cluster has no door open icon or wire...

Serious bump to an almost 5year old post.

Pop quiz: What are the mounting issues, if any, for putting an '89 dash into a '90?

Just the dash, not worried about the clusters or wiring. Both models are Si. Any issue with mounting or fitment (I'm not sure if fitment is a word but we're going to go ahead and rock it).

Thanks in advance for any contributions.

The harnesses are not the same but the dash itself is no different.

bump, Id love to know how to wire up the 90-91 cluster switches

Ive got the cluster wiring pinned into the 90-91 spots, but the switches arent the same.

My 89 dimmer harness plug clicks into the 90-91 plug no problem, but do the wires need to be repinned? I definetely need to extend them but the plug is the same atleast.

The defroster plug on my 89 wiring is completely different than the defrost switch on the 90-91 cluster, 3 wire VS 5 flat

Appreciate any help!!

You didn't wire something properly.
The wiring coming from the car that controls the CEL isn't wired correctly to correspond to the SiR cluster.
You need to swap something around, get a wire schematic to troubleshoot this.
