I looking for the tach signal wire in the ecu. I have a non-obd 91 integra.
Thanks,

 

Should be a solid blue wire. It comes from your distributor as a solid blue wire, and goes into the back of your cluster as a solid blue wire, but I'm not sure if it's still blue at the ECU.
good luck,
Jared

 

O well I wired it to the usual wire at the distributor . I tried to keep the tap hidden so put it behind the harness. I'll put some wire loom and it should look almost stock. I'm using it for my new toy, Razo RS13 Shiftlight(adj. dual shiftlight) best shiftlight imo.
