I put in a 91 cluster in my 88 civic (almost identical cluster). the plugs in the back fit fine, but when i turned on the car the gas gauge doesnt work. also the engine light was on. So then I drove away and speedo worked fine so iv been driving it like that for now. a month later now the speedo seems to read lower then im actually going...almost stuck or something...its about 20 km/hr behind only when going over 120. but at low speeds its acurate!!?? hmmmm

IS this all because of the cluster, i obviously think the gas gauge is because of the cluster, but why all of a sudden is my speedo ****ing up.

Do 91 clusters function with the 88?

thanks guys

 

no, the wiring for 88-89 is different than 90-91. you will have to do some de-pinning to get it to work right.

 

dam that sucks....makes alot of sense though
so why did the speedo work before but now its kinda slow??

 

Here is a diagram from an old post, what exaclty do i have to do to make it work? just cut some wires? Dont really understand it. any help would be great!

ok im only havin the engine temp and gas gauge not read...my speedo is fine i could use some help to

 

It's pretty simple, make your 88-89 pins look like the 90-91 pins.

 

ok im new to this so is there a diagram to show these pins or what these pins are...i know how to install a motor i dont know any electronics

 

i need help with this as well I set up my 88-89 dash harness to the 90-91 specs, and my cel stays on but it doesnt flash when diagnosing for codes. temp, and fuel dont work either. any help thanks
