The SOHC tach can be used with a DOHC swap such as SR20

You just have to rewire the SOHC tach to read the signal from the correct locations. The DOHC motor sends the signal using another wire, compared to the SOHC cluster.

  • Remove cluster.
  • Find the TAM and its wire (yellow w. red stripe)
  • Cut TAM wire
  • Run a single wire from the TAM to the engine bay, near your coil(ignition coil) cut or strip coil positive wire.
  • Attach wires
Shroud/protect your wire from heat/moving objects
What your saying here is interesting. So your telling me I can use my analog sohc s13 cluster as long as I rerun the tam wire to any positive coil signal wire?
