The '730 ECM ESC circuit is looking for a 3.9K ohm resistance in the knock sensor and the '165 KS is 100.0K ohm. You can put a resistor (From Radio Shack, et al.) to bias the 100.0K ohm KS so that it appears to the ECM as 3.9K ohm. The resistor should be between 3.8K and 4.2K ohms, and connect between the Knock Sensor wire of the ECM (GF9) and Ground. If you are building an adaptor harness like me, you can solder this between B7 and A12 of the adaptor plug that your harness plugs into. (assuming you are using the jumpered ESC connector on the firewall. If you are bringing a new wire thru the firewall, you will have to connect it and A12 with the resistor) If you are using the ESC connector on the firewall to bring the KS signal in, you will have to jumper pins "C" and "E" on the ESC harness plug. While you are building the jumper, you can add the resistor between the jumper and pin "D" (making it a 3-prong jumper) and your '165 KS will be properly biased for use in the '730 ECM
