HI, I just got my 89 H.O motor converted to efi/ to carb. I just go it firing and everything but I'm having trouble of getting my gauges to work. I want to use the stock gauges, and not go after market. I know I need to solder the wires and tap in the EFI harness. But how do I do that if there is ONLY 1 wire coming from the Water Temp Sensor and 1 wire coming from the Oil Pressure Switch??? The EFI one had a 2 pin plug in for the water temp, but I took that out and put in a 1-pin temp unit.

I've figured it out, I got it working.... The thing that confused me was the ECT (engine coolant temp) and the Temp. sending unit. The ECT got a plug in 2 pin connector. ANd the Temp sending only got one. I just tap in this to my harness and it worked!!!! And I did the samething with the oil...
