Give Dolphin a call and tell them what your hooking too, you might be able to hook the gauges to the output of the S-10 directly without the Pulse Generator. Find out how many pulses (PPM or Pulses Per Mile) the gauges are looking for and how many the S-10 outputs with my 53 and my Classic Instruments gauges I had to buy a $70 converter (At the time)from Dakota Digital to change it over. Took me a while this morning but I was able to track that part down here:
