I was trying to search the <U>CRX / EF Civic</U> forum but I couldn't seem to find the answer.
My guage cluster doesnt read RPMs, Speed, and Temperature. But the battery, fuel, and the rest work. Recently I had the stock DX guage cluster and it was working fine. So then I upgraded to a different cluster with a RPM guage on it and none of the things I mentioned, works. I had a swap and I check all my wiring for fray and any kind of damage. and I also breifly check the wiring inside the dash. I didn't find anything unusually wrong. Isn't there some kind of special wiring when switching guages from a guage with no rpm tach to a guage with one? Well i hope some of you can help me...and btw I may be looking for an SI cluster if my cluster doesnt work.

My car:
88 civic 4dr
b16 with gsr head swap

 

try this theres a civic to crx wiring diagram about half way down.
