Here is the solution you need to utilize your stock Jeep ignition switch to start your LS Conversion. The relay kit includes a pre-terminated lead that will plug directly into your ignition switch connector and the required relay to flip the key switch signal.
The stock JK start signal is 12v+ but to properly utilize the NSS on your 4l60/80 transmission which sends also sends out a 12v+ signal, you need to send a NEG key signal to your START RELAY, whether it is a stand alone relay or you are utilizing our LS POWERPLAY HARNESS.
