just as the title states.

 

It will fit, but the wiring is different for 88-89 vs. 90-91. You would have to rewire if you use the 91 cluster. Your best bet would be finding another 88-89 cluster.

 

Also the 88-9 are more square and the 90-1 are rounded.

 

no...that's just the plastic cover. Clusters themselves are shaped similar.

There is a wiring diagram floating about on how to rewire it.
All you need is a tiny screwdriver to push out the pins out of the plugs.

 

it will fit... but its the wiring that is different...

 

Yep, all 88-89 won't fit on a 90-91 at all without rewiring. Same goes for the 90-91 to 88-89. One way I've been able to tell the difference between the two is the redline on the tach (if applicable). the 88-89 has a kinda dotted matrix redline while the 90-91 is solid orange. Back me up if I'm not right.

 

correct

 

LOL! Go with a cluster that is the same year as your car! Easy!!!!!!!!

 

now where's the fun in that...?

 

Hahahhaa! The fun is not taking a long time having to rewire!! Hahahaha!

 

Well do you have anything better to do...?

Oh wait...I just noticed you're probably a girl... so you have nails to do, your hair, shave, make-up.... yeah I can imagine why you would say that

 

or you could check my sig

 

Nope, sorry. I have better things to do like change my oil and adjust the timing on my car.
I'm a girl but puhlease, I do all the work on my car!

 

It will fit if you y\use the 91 cover and brackets but you will have to do some rewiring and the dimmer controller are very different. The 89 dimmer has a bunch of resistors built it, but the 91 dimmer has them placed somewhere. You need this to make it work as the excess voltage will burn the fuse everytime. I tried it for a whole weekend and ended up using a 89 lx sedan cluster on my 89 hatch. So best bet is to just get the one for your year.
