Did not hook up the lparking light option. It starts but then shuts off after a couple seconds. I have read on the forums about the tach but there is no mention of it in my wiring diagram. When the truck shuts off the yellow and red light are on solid and the truck will not start even with the key. I have to remove the data cable to gain control of truck. Lights and radio also turn off until I remove data cable. Ram /en/qa/96273/2018-ram-1500-starts-then-shuts-off Mon, 09 Mar 2020 22:15:14 +0000
