I have an 89 Canadian 240 and i swapped in a DOHC.. Now i know that the sohc cluster doesn't support the Tachometer when you do the swap... now i just picked up 2 digital dashes with HUDS... now one is a DOHC cluster and the other one is a SOHC cluster... even when i plugged both in though..the tach is still not working... i forgot to mention though that only one of the digital dashes came with a wiring harness and it was the SOHC... i have the FSM but i'm missing the wiring diagram.. doesn't anyone know how i can repin the harness so the tach works... i would greatly appreciate it-Jack
