I've been slowly getting my CRX up to OEM and after removing the huge tach off the dash I've been to get the tach in my gauge cluster to work, It has power going to it as the needle moves up slightly when I turn the key but It has no signal

any help is appreciated as it's driving me crazy

 

shameless bump

 

check the location of the wiring. I put a 90 cluster in my 88, slightly tricky
they prob moved some wires around for the aftermarket tach idk

 

It's the stock 91 DX cluster if that helps
