Yes, that is the idea.
Christian, do you know if the resistor wire is only on the engine side of the firewall connector? I'm thinking of installing a regular wire on the engine side to trigger my HEI relay. On my truck, yes, that was the case. I pried the connector off the resistor wire and reattached the connector to a new wire that I ran directly to the power terminal of the HEI. I did the HEI before I found the overdrive. I didn't have a proper HEI power and tach plug, so I just used an insulated crimp terminal. It worked well to swap over to the HEI relay when I added that in.
