I was gonna hook my back up lights to a toggle switch and my friend kept telling me it won,t pass inspection (I had a answer for him ) and to keep him calm started running down the problem with the OEM. DAMN NEW SWITCH IS BAD. I should throw it at my friend--when he comes up. He,s a church goer and I,m not. We had that discussion before. The funny part when we go to the junk yard--he gets all the ticks on him and I don,t get any. I told him he was a TICK MAGNET and I am a CHICK MAGNET-HAHA- Still might have to use a switch like you. If I can find a USED OR ORIGINAL SENDING UNIT--as I have everything taken apart.
