Hi there, my auto crapped out for the last time so I swapped it to a NV4500 and now the high idle doesn't work in cold temperatures after initial start up. I did the necessary wiring tie-ins for the neutral safety switch and reverse lights. Do I need to hook the park wire on the old auto harness to ground via toggle switch? If so does anyone know which colored wire is the park wire on the plug for old auto tranny. The truck is an early 03 and used to have the 47re tranny. Thank you for any input, it was an absolute nightmare trying to find the correct wires for the neutral safety switch and reverse lights. Also I've tried the cut down broom stick wedged between the seat and peddle and it sucks would rather have the old automatic high idle.
