I was wondering if a gauge cluster from a 89-91 car could be used in a 86-88 car?
would there be any modifications needed to make the gauges read accurately? obviously the redline would appear differently on the tach, but could you make the existing electronics on the s4 drive the gauges from the s5?

 

i would like too know too, because my oil pressure is busted.

i was wondering that myself. i almost bought a cluster gauge from a GTUs that is at our massive import junkyard, but i didnt know if it would "bolt right up" so to speak to my S4 plugs and wires... someone find out for us.

 

pretty sure that thats a negative,
but please somebody correct me if i'm wrong

 

anyone?

 

DO A SEARCH....i have read posts before with people discussing this subject.. i think it is possible but a lot of work.. and maybe not worth the work if i can remember correctly
there ya go bro !

ohh yea i think they have different male and female plugs in the back and u would have to cut the old s4 female then connect wires to the new s5 female but like i mentioned before do a seeeearch y0 ! lol
searching is a pain sometimes but most of the time ull find what u need
aight peace

I did it, well almost. The s5 unit will plug right in, but all the guages will read wrong, and the lights wont work. I heard all you have to do is rearange the wires in the two big plugs and it will work fine. we just need to figure out how to arange them.

 

when u find out bro hook us up with the info aight?

i'm really interested to learn more about this, the s5 gauges are much cooler looking in my opinion.

 

nice and round
