Does anyone know where the wire off of the distributor would hook up to for the tachometer it’s all cutlass dash and rally gauges came factory with the tach I’ve found information that it’s the white wire for the tach on the the plug for the cluster but can’t find where the wire off of the distributor and that white wire would make a connection Ive seen on some other discussions about Grand Prix’s that there’s a spade connector under the dash which would make sense the cutlass originally had a wire that ran threw the firewall that I think was what went to the distributor but I can’t find a connection of any sort to hook that to under the dash
