I've tried to search.....Didn't find much...I have an 89 cluster with a tach....My STD 91 hatch has no tach, and I'd rather just have an entire cluster with the tach than to buy a huge external tach.

So if there is a write up anywhere for this, or if anyone can instruct me how to do this, it would be greatly appreciated.

 

I don't know if it is even possible. Just figured I'd see if it was...before I went to the junkyard and got one from a 90-91.

 

i would assume that it just plugs rite in

 

wont work, clusters are different sizes.

 

iirc the wiring is a little different. you need to use the 90-91 brackets, and cover to make it fit.

 

Using the 91 brackets and cover...how do I make the wiring work?

there's pictures of the 88-89(milky plugs), and 90-91(gray plugs) and what the wires do.

the blue plugs are for a newer year civic so ignore those. and compare where the placement of the wires are in different location, but have the same use. so you just need to move wires around.

 

Thanks for the link. I haven't had my 91 cluster off in awhile, but I swear that there were 3 plugs...I see there is a difference in the wires...but I don't know what to do with the one left over...

 

you would need a wiring diagram. i don't have links for those =/ i need to find one though I am planning to get my jdm cluster working completely my little car diagram in the cluster isn't working.

 

I think I'm going to hit up the junk yard and look for a cluster I think...seems to be too much of a pain.

thanks again for the info.

 

Hey Denz, im trying to do the same thing that you're talking about with my 91 DX... I got an 89 Si gauge cluster with a tach, and im going to try it this weekend so i'll let you know what happens.

 

as far as i know the connections stayed the same from year to year, the only thing that changed was the style of the cluster, you need 88-89 brackets and the 88-89 cluster cover.

 

if you look at my link the color AND what the wire does stays the same, but where the wire is in different spot.

look at plug E(90-91) and plug C(88-89)
second wire is High beam for 90-91, and 88-89 is driver seatbelt. now look at plug D for 88-89. second wire is high beam same color as 90-91 but on a different plug.

so you WILL have to rewire them.

 

I'm about 99% sure about there being one extra plug on the back of my 91 cluster. I'm going to go out and look within the hour. If there is...how do I go about that? That plug was just useless? It had to of done something.

Just to get things straight...I want to make my 91 F and E clips look like the 88's C and D

 

There is a third plug....its a little blue one. Has two wires going into it..a YELLOW and a YELLOW/BLACK. What would I do with this one?

 

Hey Denz, let me know what you have to do to make it work in your car.
Like I said, im trying to do the same thing to my car.
Id apprecaite it bro!
Thanks!!

 

Dammit...Dropped the thing and broke the MPH needle.....Looks like I'm going to have to buy the right one after all....SOB
