all I know and may not applied to what you are doing or have done but the ohms need to be correct to your sending unit and gauge, I installed an after market sw on mine and someone had mixed up the suppose to be correct one in the box and it wasnt the correct match.. I doubt you are having the same problem but just a thought.. I think maybe 30 ohms
