Today I installed a TC lock up switch on my truck acording to a instructional I found online. I spliced into the Orange/black wire on the ecu and jumperd the transmission relay. The converter locks up as its saposed to with the switch. The problem I am having is when I have the key on now (engine not running) there is a constant clicking comming from under the truck wich sounds like seliniod in the tranny going on and off. I cant tell if its doing it while its running though because the truck is too loud. Everything runs and shifts fine it just didnt do that clicking noise before.
